microphone may pick up your returned voice audio and reamplify it. This could
also happen if you are using a headset where the ear cushions do not completely
cover the ears, although it is probably much less likely. In either case, you should
minimize the amount of sidetone.
Typically, different sidetone null settings are needed depending upon whether you
are using the gooseneck panel microphone along with the speaker or not. Use one
of the following procedures to correctly set the sidetone level controls.
A) Sidetone Adjustment Procedure for Gooseneck Microphone with
Speaker turned on:
1 Turn on the Mic switch. Set Mic select switch to panel.
2 Turn the level control to a comfortable level.
3 Speak into the microphone while turning the sidetone null control slowly back
and forth. There should be a point where your voice (and any accompanying
acoustic feedback) is the lowest. This is the null point.
B) Sidetone Adjustment Procedure for Headset:
1 Turn on the Mic switch. Set Mic select switch to headset.
2 Turn the level control to a comfortable level by having someone talk to you from
another station.
3 Speak into the microphone while turning the sidetone null control slowly back
and forth. There should be a point where your voice (and any accompanying
acoustic feedback) is the lowest. This is the null point.
C) System Sidetone Adjustment
1 Turn off all the microphones on sub-stations and beltpacks.
2 Followed by A) and B), adjust sidetone on MS-800 main station.
3 Turn on the microphone on sub-station and beltpacks one by one, and then
adjust the Sidetone to satisfied level.
12. Remote Mic Kill Switch (RMK)
The Remote Mic Kill (RMK) switch will turn off the microphone of every beltpack
remotely. If the Talk Functions of a large number of beltpacks have inadvertently
been left activated, incidental noise and talking can make it difficult or impossible
