signal originates at the KB-702 station or if the speaker on/off switch is
turned off. The tone alert plays through both the speaker and headset if the
speaker on/off switch is turned on.
4. Volume Control: Turn this control to set the volume required on the
speaker or headset. This control does not affect the tone alert level or the
program input level.
5. Sidetone Control: Sidetone is the level of your own voice that you hear
while talking on the intercom. Setting a comfortable level of sidetone will
ensure that the intercom line sounds alive and also helps you modulate
your voice relative to other voices on the line.
Typically, different sidetone null settings are needed depending upon
whether you are using the speaker. Use one of the following procedures
to correctly set the sidetone level control.
Sidetone Adjustment Procedure for Headset:
1. Set the intercom level control to a comfortable level by having
someone talk to you from another station.
2. Press the talk button and speak into the microphone while turning the
sidetone null control slowly back and forth until you hear your voice
at a comfortable level in the headset.
Sidetone Adjustment Procedure for Gooseneck Mic (KB-702GM only) or
hand-held push-to-talk mic with the speaker turned on:
1. Set the VOX control fully counterclockwise to disable this feature.
2. Set the intercom level control to a comfortable level.
3. Press the talk button and 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)
disappears. This is the null point.
4. Readjust the VOX control. (Refer to the VOX control paragraph in
this section.)
6. Program Level Control: Adjust the program level control to set the
program audio level heard in the headset or panel speaker.
Note: Do not force the trimpots past their stop points. This will damage
them.
7. Speaker On/Off Switch: The speaker on/off switch turns the front panel
speaker on or off. This switch also controls whether the tone alert is heard
through the speaker. The speaker volume will automatically dip whenever
the talk function is set, unless the VOX function is disabled.
8. Mic Select Switch (KB-702GM only): The mic select switch selects
whether the panel microphone or the headset microphone is active. If the
VOX feature is enabled, it is only operational when the panel microphone
is active.
9. Channel Switch: This switch selects whether the speaker station is active
on intercom channel A or channel B.
10. Headset Connector: The headset connector is located on the front panel.
All Clear-Com headsets are recommended for use with the KB-702. The
Clear-Com handheld push-to-talk microphone will also plug into the
