The screen is blue.
You connected an external 
PAL camera to the Camera 1 
In  
connector, 
which 
deactivates the internal 
camera.
Do one of the following:
• If you plan to use an external PAL camera all of the 
time, go to System > Admin Settings > Cameras and 
set the Primary Camera setting to 1.
• If you want to view video from the external PAL 
camera, but do not plan on using this camera all of the 
time, press 
 Camera on the remote control and 
select the appropriate camera source.
Note that when you disconnect the external PAL 
camera, the internal camera reactivates. To view 
video from the internal camera, press 
 Camera on 
the remote control and select the appropriate camera 
source.
No video from the 
external camera.
Camera inputs and outputs 
are not connected correctly.
Refer to 
on page 
 for information on how to connect an 
external camera correctly.
You connected a composite 
video output device using the 
S-video to RCA adapter, but 
you did not set the video 
format to Composite.
Go to System > Admin Settings > Cameras (page 2) 
and set the Video Format setting to Composite.
The video is not 
centered on the LCD 
screen.
The screen is not calibrated 
correctly.
The Mobile Responder comes with an auto-calibration 
feature. However, in order for this feature to properly 
center the video on the screen, you must be viewing 
full-screen video. To view full-screen video and properly 
calibrate the screen:
1. Go to System > Admin Settings > Monitors > 
Monitors and enable Zoom video to fit screen OR 
set the Monitor 1 aspect ratio to 4:3.
2. Press 
 Near on the remote control to view 
full-screen video.
3. Press the Select LCD button to auto-calibrate the 
screen (refer to 
 on page 
 
for an illustration showing where the Select button is 
located).
Cannot receive or 
send stereo audio.
Stereo audio is not available 
with the built-in microphone 
and speakers.
To receive stereo audio, connect external speakers or 
speakers on a headset to the Line Out 
 connector.
To send stereo audio, connect an external digital 
microphone, such as a Polycom microphone or a 
SoundStation VTX 1000 conference phone, to the 
Conference-Link  
connector.
