MS-702 TWO-CHANNEL MAIN STATION
1-4
3. Ton e A l e rt : An audible tone alert can be enabled to sound when a call signal
is received on either channel. This can be useful when the operator's
attention has been drawn away from the MS-702 indicator panel. Press the
tone alert button to alternately enable or disable the audible tone alert. The
button illuminates blue when the audible tone alert is enabled. When
enabled, the tone alert will sound when a call button on a beltpack or station
is pressed. The tone alert will not sound if a call signal is originated at the
MS-702 station. The level can be adjusted by the control on the rear panel
(See number 4 on the rear panel diagram later in this chapter).
5. Listen Level Controls: Each channel has a separate listen level control. Turn
these controls to set the listen level you need on each channel. Turn the
control completely counterclockwise to silence a channel.
6. Sidetone Controls: Each channel has a sidetone null 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 adjust your voice relative to other voices on the line.
Typically, different sidetone null settings are needed depending upon whether
you are using the gooseneck panel microphone along with the speaker. Use
one of the following procedures to correctly set the sidetone level controls.
Sidetone Adjustment Procedure for Gooseneck Microphone with Speaker
turned on:
1. Tu r n o f f t h e party-line link (A+B) switch.
2. Turn the level control for channel B all the way down. Set the level
control for channel A to a comfortable level.
3. Press the channel A talk button and speak into the microphone while
turning the sidetone null control for channel A slowly back and forth.
There should be a point where your voice (and any accompanying
acoustic feedback) disappears. This is the null point.
4. Repeat this procedure for channel B by turning the channel A level
control down and adjusting the channel B controls.
Sidetone Adjustment Procedure for Headset:
1. Tu r n o f f t h e party-line link (A+B) switch.
2. Turn the level control for channel B all the way down. Set the level
control for channel A to a comfortable level by having someone talk to
you from another station.
3. Press the channel A talk button and speak into the microphone while
turning the sidetone null control for channel A slowly back and forth
until you hear your voice at a comfortable level in the headset.
4. Repeat this procedure for channel B by turning the channel A level
control down and adjusting the channel B controls.
7. Program ON-OFF-INTRPT Switches: The program on-off-intrpt switches
are used to manually or automatically control program audio feed into the
intercom lines. The settings are as follows:
• ON: The channel will receive program audio when the switch is set to
on. The audio level for each channel can be adjusted with the program
level trimpots.
