Default SS 6900n V6 microphone wiring

The standard fist mic which comes with the Superstar 6900N, and many of the other clones, has 3 buttons in addition to the PTT switch.
If you are wiring up another microphone for use with this radio it is important to not connect any wire to pin 4 on the 4 pin mic plug.


FEATURES, FUNCTIONS AND SPECIFICATIONS:
4-Pin Dynamic Microphone, 150 Ohm

WIRING OF MIC CABLE:
1 Common Ground
2 Mic Audio
3 PTT (connected to Pin 1 for TX)
4 +5V
Never ground Pin-4, this will damage the radio.
