Audio volume
adjustment
The AS-801 has three different Audio Source
inputs (S1,S2,S3). Each audio source has an
adjustable volume trimmer on the printed circuit
board. You can adjust the volume either by the AS-
801 volume adjustment or by the volume adjust that
is located on the Audio Source itself. To adjust the
message level, do the following:
1) Have someone call you (do not call yourself
through your phone system).
2) Place the line "ON HOLD".
3) Adjust the corresponding trimmer.
4) Take the caller "OFF HOLD".
5) See if the level was good; if not, repeat from
step 2 until the proper level is achieved.
