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.
C. Changing the Call Time-Out
The E-10 and E-20A are equipped with an adjustable call time-out feature which automatically hangs-up the unit after
the pre-set time has elapsed. To change the time-out, adjust the call time pot as shown above. The time can be adjust-
ed from approximately 6 seconds to 5 minutes (factory set to approximately 3 minutes).
D. DIP Switch Programming
1. Auto Answer Feature ON/OFF (DIP Switch 1)
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.
2. Call Timer ON/OFF (DIP Switch 2)
The call timer switch allows the user to turn off/disable the
call timer feature. With DIP switch 2 in the OFF position, the
call time will be unlimited and the speaker phone will not
automatically hang up until a 300ms or longer CPC break is
detected. Warning: If your telephone line/phone system
extension does not supply a 300ms or longer CPC break, the call timer feature must be used, DIP switch 2 ON.
3. VOX (Talk/Listen) Switching Speed (DIP Switch 3)
With DIP switch 3 in the ON position (factory default), the VOX switching speed (delay time between talk and listen
mode) is set to FAST (0.3 seconds). In the OFF position, it is set to SLOW (0.7 seconds).
