System Components
Before using your LifeSize video communications system, familiarize yourself with its
components.

LifeSize Camera
Near end participants and objects in a video conference call are located in the same room as
your LifeSize video communications system. Far end participants and objects are in a
remote location. The camera captures near end video to send to far end participants in a
call.

Note: You can connect two cameras to LifeSize Room. Only one camera can be active at
a time.

LifeSize Video Communications Systems User Guide 3

LifeSize Phone
The LifeSize Phone high definition audio conferencing speakerphone is fully integrated with
LifeSize video communications systems and doubles as the microphone for a video system.
LifeSize Phone provides 16 microphones in a circular array to capture local sound. You can
also use the LifeSize Phone to place and hang up calls.


LifeSize Remote Control
The LifeSize remote control provides wireless control of all LifeSize video communications
system functions and enables you to navigate the user interface, place and receive calls,
and control the camera.

The infrared (IR) sensor for the remote control is located in front of the camera. Stay within
10 meters (33 feet) of the camera when using the remote control.


LifeSize Codec
The LifeSize codec compresses outgoing video and audio content and data, transmits this
information to far end of a call, and decompresses incoming information. You should not
need to interact with the codec once it has been properly installed in your environment.

Third Party Display
A third party display connected to the LifeSize codec enables you to access the user
interface and view video images during a video call. You can connect two displays to
LifeSize Room.


Navigating the User Interface
When your LifeSize system is idle, a screen saver appears on the display, or the screen is
black. An incoming call or pressing any button on the remote control automatically invokes
the system.

Note: Administrators can configure LifeSize systems for use in telepresence rooms in
which a conference administrator controls calls from a control panel or where users
interact with the system using a connected phone. If telepresence is enabled on
your LifeSize system, only an administrator can access the user interface when the
system is idle. During a call, you can perform only the following tasks in the user
interface:
• Change the behavior of the numeric keys on the remote control from Touch
Tones to Presets. Refer to “Using Camera Presets During a Call” on page 22.
• View call statistics. Refer to “Viewing Call Statistics” on page 25.
• Choose video input with the near and far keys on the remote control. Refer to
“Controlling a Near End Camera” on page 11 and “Controlling a Far End
Camera” on page 21.

The Main Screen
The user interface includes functions available to all users as well as preferences and
functions restricted to administrators with a password.
The main screen has three sections:
• The top of the screen displays system information (such as the system name and phone
number). This information is hidden during a call. Video images from the active camera
connected to the system appear in a small window below the system information.
• The center of the screen contains the REDIAL list and the Voice Call and Video Call
buttons. From the REDIAL list you can place a call by selecting a number from a list of
recently dialed numbers. Use the Voice Call and Video Call buttons to dial a number
manually.
• The bottom of the screen contains the system status bar and the navigation bar. The
system status bar indicates system and network status, including the number of voice
and video calls, the time and date, or the duration of a call when a call is in progress.


When the system is booting, status also appears at the top of the REDIAL list to indicate
the current state of the system. The following table identifies the icons that can appear in
the system status bar.

Icon Condition

Video Indicates the number of video calls in progress. Each orange circle that
appears to the right of the video icon represents a video call in progress.

Voice Indicates the number of voice calls in progress. Each orange circle that

Note: Your administrator can require a password to access these preferences.


Controlling Cameras
Become familiar with how to control a camera connected to your system before placing a
video call. To prevent far end users from controlling your near end camera during a call,
contact your administrator.

Controlling a Near End Camera
To adjust the near end camera when the system is idle, select the camera by pressing the
near camera button on the remote control. Use the following buttons on the remote control
to adjust the camera angle:

Remote Control Button Function

Left and right arrows pan the camera.
Up and down arrows tilt the camera.

Zoom in and zoom out keys zoom the camera.

If you are using two cameras with a LifeSize Room system, only one camera can be active
and capturing video images at any time, even if both are connected to the system. To specify
the active camera, refer to “Selecting Input” on page 23. On the Primary Input and
Secondary Input selection screens, the inactive camera appears as a camera icon in a
grey selection box. The active camera appears as a selection box with its video image.
The blue LED of the active camera is brightly lit when the system is in use. The blue LED of
the inactive camera is dimly lit. If you disconnect the active camera, the inactive camera
automatically becomes the active camera. Reconnecting the disconnected camera does not
change the active camera selection.


Configuring Camera Presets
A camera preset is a predefined camera position that is associated with a numeric key on
the remote control. Camera presets enable you to quickly change the position of the near
end camera during a call by pressing a single key on the remote control instead of using the
arrow and zoom keys. Far end participants see the video image without the delay that is
associated with using more than one key to position the camera.
You can configure and use presets in the Primary Input and Secondary Input screens
before placing a call and from any video screen during a call. To configure and use presets
during a call, you must first select Presets from the Call Manager screen. For more
information about using presets during a call, refer to “Using Camera Presets During a Call”
on page 22.
You can save nine presets. When presets are available for use, icons for the numeric keys
(0 through 9) followed by the word Presets appear in the navigation bar of the user
interface.
Configuring presets before placing a call ensures that you can quickly change the near end
camera position during the call. To configure a preset for the near end camera before
placing a call, follow these steps:
1. Select the near end camera and adjust its position. Refer to “Controlling a Near End
Camera” on page 11.

2. Press and hold a numeric key (1 through 9) on the remote control until you hear a beep.
The current position of the camera is associated with the key. Preset x saved, where x
is the numeric key associated with the preset, appears above the status bar.

If you choose a numeric key that already has a preset configured, it is overwritten. An
administrator can lock existing presets to prevent them from being overwritten. If an
existing preset associated with the key is locked, Preset x locked appears on the
screen. The 0 key, when used as a preset, always moves the selected camera to the
default position and cannot be overwritten. If you use a preset that is associated with a
second camera connected to LifeSize Room, the position of the second camera
changes and the second camera becomes the active camera.

3. To test the preset, use the arrow keys to move the camera to a different position, and
press the numeric key associated with the preset to move the camera to the preset
position. Preset x, where x is the numeric key associated with the preset, appears
above the status bar.


Managing Near End Video Quality
Before you place a call, examine the near end video image from the camera connected to
your LifeSize system. If the image flickers, colors appear unbalanced, or the image appears
too dark, you may need to adjust the room lighting or camera settings. For more information,
refer to “Adjusting Room Lighting” on page 32 and “Camera Issues” on page 32.

Placing a Call
You can place a video or voice call with your LifeSize system in the following ways:
• Select a stored number from the REDIAL list on the main screen or from the directory.
• Manually dial a number using the following:
- Video Call or Voice Call buttons on the main screen
- video or voice keys on the LifeSize Phone if connected to your system

Placing a Call from the REDIAL List
The REDIAL list on the main screen stores up to 15 recently dialed numbers. A scroll bar
appears when more than five entries are available for selection. The oldest entry in the list is
automatically removed when the system receives a call after the maximum number of
entries has been reached.
The last call placed always appears at the top of the list. The entry includes the name of the
party called and an icon that indicates whether the number is a voice or video
number. The entry’s number (and bandwidth if the entry is a video number) appears
below the list.
To place a call from the REDIAL list, use the arrow keys on the remote control to select an
entry and press the OK key.
To change the bandwidth for a video call on the REDIAL list before placing the call, select
Video Call on the main screen, press the OK key twice, and use the right arrow key to
select the bandwidth list. Change the bandwidth to a setting other than Auto.

Note: Selecting Auto from the Video Call selection before placing a call does not change
the bandwidth selection for an entry on the REDIAL list that does not have Auto as
its last called bandwidth.
You can adjust the maximum number of entries that appear in the REDIAL list by adjusting
the Maximum Redial Entries preference in User Preferences : Calls. You can also add
entries from the REDIAL list to the local directory and manually remove entries or lock them
to prevent them from being automatically removed when the maximum number of entries is
reached. For more information, refer to “Managing the REDIAL List” on page 27.


Placing a Call from the Directory
The directory stores a list of names and numbers from which you can place calls. The
directory includes three subdirectories: the local, corporate, and meetings directories. An
entry in the local or corporate directories contains dialing information for a single device. An
entry in the meetings directory contains dialing information for two or more devices. When
you select an entry in the meetings directory, the system dials all the devices in the entry.
Entries in the local and meetings directories are stored on the system and can be modified.
The corporate directory is read only and managed by your administrator.
To place a call from the directory, follow these steps:
1. From the main screen, press the button on the remote control to access the
directory.

2. Use the arrow keys to select either the Local, Corporate, or Meetings directory, and
press OK.

You can browse the directory using either the alphabetical or hierarchical method. When
you use the alphabetical method, the entries appear in alphabetical order and you can
select an alphabet group in the Browse column to quickly navigate to an entry.
Hierarchies are predefined organizational units similar to folders or directories on a
computer system. You can place an entry into a hierarchy when you create the entry or
at any time by editing the Hierarchy field when editing the entry. For more information
about creating hierarchies, refer to “Managing the Directory” on page 29. Using the
hierarchical method, you can select a hierarchy in the Browse column to locate an
entry. To move down one level in Browse, press OK. To move up one level, press the
button.

4. Press OK on the remote control to place the call.

Note: If an entry in the local or corporate directory has more than one number, the
symbol appears in the NUMBERS column. Press OK and select the number you wish to
call from the menu that appears. Press OK to place the call.

Troubleshooting
The following sections describe symptoms, possible causes, and potential solutions for
common problems you may encounter with your LifeSize system.
When experiencing a problem, visually inspect the unit. Ensure the system has not been
exposed to water or heat sources or appears physically damaged.
Improperly connected or loose cables are common causes of problems with hardware units.
When investigating a system problem, first inspect all the external controls and cable
connections. Ensure that connections are correct and secure, and that nothing is obstructing
the cables. Contact your administrator for information about proper cabling.


Adjusting Room Lighting
You can assist the system to maintain the best possible image quality by altering the
environmental lighting and background colors of your environment. The optimal lighting for
standard conference rooms using LifeSize systems is 300 to 500 LUX. Consult your
administrator or LifeSize Channel Partner for details about the specific lighting requirements
for your environment.
If your LifeSize system detects insufficient lighting for an attached camera, a low or very low
light indicator appears in the status bar of the main screen. Refer to “The Main Screen” on
page 6 for a description of the low and very low light indicators. If light levels are too low you
may consider adding artificial lighting. Indirect light from shaded sources or reflected light
from pale walls often produces excellent results.
Avoid the following:
• direct sunlight on the subject matter, the background, or the camera lens which creates
harsh contrasts
• direct illumination of the subject matter and camera lens
• colored lighting
• harsh side lighting or strong light from above
You can also improve dim scenes by adjusting the camera brightness. Refer to “Adjusting
Camera Brightness” on page 33.

Camera Issues
The infrared (IR) sensor for the remote control is located in front of the camera. The range of
the remote control signal is 10 meters. If your system is not responding, first ensure the
camera is positioned correctly and that you are using the remote control within 10 meters of
the camera.
If you are unable to pan, tilt, or zoom the camera, ensure the remote control contains three
AAA batteries that are in good working condition. Also verify that no objects are obstructing
the sensor on the front of the camera.
If no video displays from the camera, ensure the camera is connected to the LifeSize system
with a camera cable to the appropriate camera input or contact your administrator. Also
ensure that the primary input is set to the high definition camera as described in “Selecting
Input” on page 23.
Verify that the blue LED on the front of the camera is lit, indicating that power is active, and
reboot the system if necessary to verify that the camera turns on. To reboot the system, refer
to “Power and Connectivity Issues” on page 36.


Adjusting Camera Brightness
Camera brightness refers to the amount of light received through the lens of the camera.
You can improve dim scenes by adjusting room lighting and manually adjusting the camera
brightness. The HD Camera Lighting indicator in User Preferences : Diagnostics : High
Definition Camera shows the room lighting conditions for the camera. If the condition is
other than Perfect Light, adjust the room lighting or camera brightness. To adjust camera
brightness, set the HD Camera Brightness preference in
User Preferences : Diagnostics : High Definition Camera.

Adjusting Camera White Balance
Camera white balance refers to how a camera references the color white, which is a mixture
of all colors. Adjust the white balance when video color appears to be unbalanced. White
balance is affected by the type of light source. To adjust the camera white balance adjust the
HD Camera White Balance preference in User Preferences : Diagnostics : High
Definition Camera.

Adjusting the Camera Anti-Flicker Preference
Lights powered by a 50 Hz power source can produce a flicker that the camera captures and
transmits to the system. If you are using lights powered by a 50 Hz power source and
observe a flicker in the video displayed in your system, select the 50 Hz option in User
Preferences : Diagnostics : High Definition Camera : Camera Anti-Flicker. The default
option is Auto.
Some camera exposure settings designed to be used in rooms lit by sunlight may result in a
flicker. To remove the flicker, increase the HD Camera Brightness setting in User
Preferences : Diagnostics : High Definition Camera.

VGA Input Issues
You can adjust the horizontal and vertical positioning, and brightness and contrast of VGA
input from a device connected to the VGA input on the LifeSize codec. Typically, the
VGA input device is a laptop or personal computer that is used to send data during a
presentation (for example a spread sheet or a slide show). You can also perform coarse or
fine tuning of the clock frequency, and adjust the percentage of scaling so the image best fits
your display. To adjust VGA input settings, access User Preferences : Diagnostics : VGA
Input.


Display Issues
The following issues are related to the user interface or the display.

Display Failures
If data does not appear on the display, ensure cables are properly connected on the display
and that the display cable is connected to the Display 1 output on the back panel of the
codec. Also ensure you have selected the correct input. Refer to “Selecting Input” on
page 23 for more information.
If the video image and user interface appear washed out or too bright, examine the input
settings of your HDTV to make sure the HDTV is displaying the appropriate resolution.
Some HDTVs (particularly plasma displays) allow you to configure the native resolution of
the input device from the HDTV administration interface.
If you are using a second display with LifeSize Room and nothing appears or you see data
from only one input, you may be using an unsupported display or the secondary input is
turned off. Navigate to User Preferences : Appearance : Secondary Display Layout. If
this preference is disabled and you are unable to modify it, you are using an unsupported
display. Otherwise, ensure that the VGA input for the second display is connected.

Poor Quality Display
If you have poor quality or unreadable data on the phone display, adjust the User
Preferences : Appearance : LCD Contrast setting. LifeSize recommends using the default
setting (6).
If the colors on the display appear incorrect, verify that the RGB cable is properly connected
to the display.

Missing Input
If you have not connected all possible video inputs, the input selection dialog displays a
black image by default. Connect the necessary input or choose a different input as
described in “Selecting Input” on page 23.

Poor Quality Far End Video
During a call, the LifeSize system automatically selects the best video algorithm based on
the video source and capabilities of the remote system. If you experience poor motion
handling or visible tiling in the far end picture during a video call, contact your administrator.


Audio Issues
The following issues are related to the audio quality.

Absent Dial Tone
If you do not receive a dial tone after pressing the or key to initiate a call, ensure
the line out is securely connected.
An absent dial tone may also result from an unavailable analog phone line connection. If you
are connecting with PSTN, ensure the analog phone connection is secure and that it is
connected to an active phone line jack.

Problematic Sound Quality
The LEDs on the LifeSize Phone flash blue to indicate an incoming call. If you are unable to
hear the phone ring when an incoming call arrives, adjust the volume using the up and down
volume key. If you still experience audio problems, adjust the Ring Tone Volume preference
in User Preferences : Audio.
Muffled audio reception from the far side may be caused by highly reverberant rooms. If you
are experiencing poor audio reception, add more sound absorbency to the room and speak
in close proximity to the phone or microphone.
Degradation in the audio quality can also be caused by faulty microphones or dust and
debris accessing the connected phone. Do not use any kind of liquid or aerosol cleaner on
the phone. A soft, slightly damp cloth should be sufficient to clean the top surface of the units
if necessary.
When using an external microphone, do not place the microphone less than 5 feet away
from the loudspeaker. Also, ensure the external microphone gain is not set too high or
distortion or an echo may occur.

Distorted Audio
Ensure that speakers are not obscured or damaged at either end of the call. Do not stack
items on top of the phone. Ensure both ends are not muted. Verify that the audio out cables
are properly connected to the display and that any external speaker systems are powered
and configured correctly. If an external speaker system has its own volume control, adjust
the volume to near maximum (in the range from 7-10) on the LifeSize audio output and
adjust the volume control on the external speaker system for the best results.


Power and Connectivity Issues
If a call does not successfully connect, verify that you have dialed a working number and
that the far end destination is powered on and available. Verify that the network is ready and
available. Network status is indicated at all times in the status bar. If the LifeSize system is
connected to the local network, a green network status icon appears. A yellow or red
network status icon indicates a problem with the network connection. Refer to “The Main
Screen” on page 6 for a visual depiction and description of the network status icons.
You may need to reboot a system that is not responding to commands from the remote
control. To reboot the system, access User Preferences : Diagnostics : System Reboot.
