11. Sidetone zero-adjusting

The UTS-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 here your own voice back in the speaker or headphones. This is
called sidetone. If you are using the UTS-200 with a microphone and speaker, sidetone
could cause unwanted feedback, since the 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 of these cases, 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 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.
