1 - 5

OFF: The channel will not receive program audio when the switch is set 
to 

off.

INTRPT: Pressing the 

talk

 button will interrupt the program when this 

switch is set to 

intrpt.

Note:

You can set this feature so that pressing the call button for a channel, 
rather than the talk button, interrupts the program audio. See the 
section “Resetting Program Interrupt Options” at the end of this chapter. 

8. Program Level Controls:

 Adjust the program-level controls to set the 

program audio level heard on the intercom. There are three program-level 
controls. The 

program level

 knob to the left of the speaker 

on-off

 switch 

adjusts the level of program heard in the headset or panel speaker of the 
MS-702.

The program levels heard on each intercom channel line can be individually 
adjusted, but this is intended to be a one-time setting made when the 
MS-702 is set up. This is done using the screwdriver level adjustment trim-
pots adjacent to the 

program on-off-intrpt

 switches on channels A and B. Set 

the 

sidetone null

 controls and the 

program level

 knob fully counterclockwise 

when adjusting the individual channel program-level trimpots. After the pro-
gram-level trimpots are properly adjusted, use the procedure listed in the 

Sidetone Controls

 section on this page to set the sidetone level.

Note:

Do not force the trimpots past their stop points. This will damage 
them.

9. Party-line Link (A+B) Switch: 

When pressed, the 

party-line link (A+B)

 

button combines both intercom channels into one; for example, for 
rehearsals. The party-line link button illuminates amber when on, and all of 
the stations on the B channel will be moved onto the A intercom line. This 
will allow communication between everyone on both channels at once.

In this mode, the channel B controls and switches will be inactive. Since the 
wiring for the B channel has been now added to the A channel, the 

sidetone 

null

 control for channel A may require some readjustment.

10. Speaker ON/OFF Switch:

 The 

speaker on/off

 switch turns the front panel 

speaker on or off. This switch does not affect whether the tone alert is heard 
through the speaker. The speaker volume will automatically dip whenever 
the panel or headset microphone is on.

11. Remote Mic Kill Switch:

 The 

remote mic kill

 (RMK) switch will turn off the 

talk function of every beltpack on channels A and B. If the talk functions of 
a large number of beltpacks have inadvertently been left activated, incidental 
noise and talking can make it difficult or impossible to communicate on the 
party-line intercom. The RMK switch can be pressed to quiet the line in this 
situation. Those needing to communicate can then set their talk functions to 

on

 as needed.

Note:

The RMK switch can only function if the MS-702 main station is 
powering all of the stations in the system. The switch momentarily 
interrupts power to the other beltpacks and stations in the system. If 
there are other power supplies or main stations in the system, then 
the RMK switch cannot interrupt power and therefore cannot work.
