Motorola APX 8500 Installation Manual page 41

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 detects a HIGH for the emergency pin state, and assume that emergency
has been activated. This attempts to power on the radio, and results in excessive current draw
and incorrect radio operation. Refer to
wiring of emergency in dash mount.
