can also be sent while talking if required. The call button will light when pressed,
or whenever a call signal is present on the selected channel. An internal option
jumper can be set to allow the call button to light when a call signal is present
on either channel.

Tone Alert
: An audible
tone alert
can be enabled to sound when a call signal is
received on the selected channel or either channel. This can be useful when the
operator’s attention has been drawn away from the KB-702 indicator panel. The
audible tone alert level can be adjusted or turned off by an internal control. The
tone alert will not sound if a call 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:
a. Set the
intercom level
control to a comfortable level by having someone talk
to you from another station.
b. Press the
talk
button and speak into the microphone while turning the
s
idetone null
control slowly back and forth until you hear your voice at a
comfortable level in the headset.
