Figure 2-8. Radio Installation (O2 Mid Power Remote Mount) - Motorola ASTRO APX O2 User Manual

Standard Configurations Planning the Installation
NOTE: In dash mount configuration, it is mandatory that a rear accessory cable be attached at the
back of a mid power transceiver, in order to ground the Emergency pin to GND. Or, an
emergency footswitch or pushbutton switch must be attached at the back of a mid power.
If the emergency pin is not grounded, upon the attachment of the A+ cable at the DC
connector, the radio will detect a HIGH for the emergency pin state, and assume that
emergency has been activated. This will attempt to power on the radio, and will result in
excessive current draw and incorrect radio operation. Refer to
details and recommended wiring of emergency in dash mount.
