This pin must be connected to ground by jumper on accessory cable if emergency is disabled, even if disabled by
CPS. If enabled, this line must be grounded via a switch, which is normally closed. The emergency debounce time
is programmable via CPS.
2
Pulling this line to ground will activate PTT function, activating the AUX_MIC input.
3
Fixed level (independent of volume level) received audio signal, including alert tones. Flat or de-emphasis are pro-
grammed by CPS. Output voltage is approximately 100 mVrms per 1kHz of deviation. The DC offset is 1.4V.
4
This output 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.
5
This microphone signal is independent of the microphone signal on the front microphone connector. The nominal
input level is 80mVrms for 60% deviation when used for motorcycle, but can also support 300 mVrms for future
APCO accessories. The DC impedance is 660 ohms and the AC impedance is 560 ohms.

Table 2-1
in Chapter 2 for wiring options.
Note: Please see the XPR 4300/4350/4500/4550 Basic Service manual (Motorola publication part number
6816816H01) for more detailed descriptions of these pins.
