Color Bar

The Color Bar screen is used to test the color setting on the

television monitor. Highlight the View Color Bars icon and press the

SELECT button on the remote control. Color bars appear full screen.

Color Bar screen.

Audio

The Audio screen is used to generate a tone and view the audio

levels of the ViewStation.

To generate a tone:

• Highlight the Generate Tone icon and press the SELECT

button. Adjust the volume controls on the ViewStation and

television monitor to comfortable levels.

• Press any button to stop the tone. If the system is in a call

the far site also hears the tone.

To view audio levels:

• Highlight the Audio Meter icon and press the SELECT

button on the remote control.

• The Audio Meter screen indicates the audio level of all

audio inputs connected to the ViewStation. Speak into the

microphone to test the audio level.

Near End Loop

The Near End Loop screen allows you to test the encoder/decoder

on the ViewStation. This can help you diagnose a problem with a

video call. Press any button on the remote control to stop the loop.

Far End Loop

The Far End Loop screen only appears during an H.320 or V.35 call

and allows you to test the encoder/decoder on the ViewStation. This

can help you diagnose a problem with an H.320 or a V.35 video call.

If you perform a far-end loop test during a call, the far site sees its

own loop. Press any button on the remote control to stop the loop.
