13. Sidetone zero-adjusting
The WS-200 uses full-duplex audio (the same as a conventional telephone line) in which the talk
and listen audio are sent and received on the same line. Thus, when you talk on a channel, you will
also hear your own voice back in the speaker or headphones. This is called sidetone. Unexpected
sidetone could cause feedback between speaker and microphone. In either case, the sidetone
should be minimized. Sidetone zero-adjusting is for this purpose. Adjust the handle, make you hear
yourself minimize.
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
