1. Check and unscrew the set screw in the mic mounting flange to make

sure it is clear of the threads in the bushing.

2. Screw the microphone into the bushing hand tight.
3. Turn the set screw on top of the mic mounting flange clockwise to

lock the microphone in place.

19. Headset Connector: The headset connector is located on the front panel.

All Clear-Com headsets are recommended for use with the MS-702. The

following is a description of the characteristics of a suitable headset:
Mic Type --- Dynamic; 150 to 250 ohms impedance; -55 dB output level

Headphone --- Dynamic; 50 to 2000 ohms impedance

The wiring of the headset is to be as follows:

Pin 1 --- Mic common

Pin 2 --- Mic hot

Pin 3 --- Headphone common

Pin 4 --- Headphone hot

The mic and headphone wiring in the headset cord must be individually
shielded. Do not connect pins #1 and #3 together. Headset extension
cords or headset “Y” cables are not recommended because they will
increase crosstalk between channels.

26. Short Lights: There is one red light for channel A and one for channel B.

These lights illuminate when the MS-702 senses a short or overload on

the associated channel. When the fault is removed, the MS-702 will

automatically reset and the light will go out.

They should be configured when the system is set up, but are not changed
