A. Adjusting Speaker Volume
The
SPKR VOL
pot can be adjusted to increase or decrease the speaker volume to the level desired as shown above.
B. Adjusting the Microphone Volume
In certain noisy locations (background traffic, machinery or wind), the microphone volume may need to be decreased.
A symptom of this is one-way talk path, in which the distant party cannot be heard over the speaker. A
MIC VOL
pot
is provided for increasing or decreasing the microphone volume.
Note:
If the microphone volume is set too high or too
low, one-way talk path may occur.
D. DIP Switch Programming
DIP switch 1 is for turning the Auto Answer feature ON and
OFF. The speaker phones are factory set to auto answer
when an inbound call is detected.
