1
Pulling this line to ground will activate PTT function, activating the AUX_MIC input.
2
Fixed level (independent of volume level) received audio signal, including alert tones. Flat or de-emphasis are
programmed by CPS. Output voltage is approximately 330 mVrms per 1kHz of deviation.
3
This input is used to detect when a rear microphone accessory is taken off-hook, to override PL to alert the user to
busy traffic prior to transmitting.
4
This microphone signal is independent of the microphone signal on the front microphone connector. The nominal
input level is 80mVrms for 60% deviation. The DC impedance is 660 ohms and the AC impedance is 560 ohms.
5
See Figure 2-3 and Figure 2-12 for wiring information.
