A correctly installed AP400 virtually runs by itself. Typical operations
involve changing volume of an output, muting an input or output, or
handling calls on the connected telephone handset. For most installa-
tions a custom remote control (optional) would be used.
Controlling Volume
When participating in a conference, you may find it necessary to
increase or decrease the volume of a particular output. For instance
when the audio at a distance location is too soft, adjust the output to the
speakers so that the level is comfortable.
To adjust the volume
:
1.
Determine which output needs to be adjusted.
2.
Press the OUTPUTS button, select appropriate output and scroll to
the GAIN selection. Press ENTER.
3.
Adjust the gain level using the
▲
and
▼
buttons. You should be
able to hear the volume level adjust while increasing or decreasing
the gain.

. Press ENTER when you reach the desired volume level.

(or unmute) a particular input or output.
