Antenna Mounting
The recommended mounting location for the antenna is on the chassis or other stable part
on the motorcycle as far from the driver as possible.
Mount the antenna and shorten the antenna cable using the provided instructions.
Power Cable Installation
Before applying 13.8VDC primary power to radio for the first time, inspect wiring going
to accessory connector very carefully. Ensure that pin 1 (speaker+), and pin 2 (speaker-)
ARE NOT connected to chassis ground. Failure to follow this precaution may result in
permanent damage to the transceiver and require replacement of audio power amplifier
integrated circuit and/or complete transceiver board.
This radio must be operated only in negative ground electrical systems. Reverse polarity
will cause the cable fuse to blow. Check the vehicle ground polarity before you begin
installation to prevent wasted time and effort.
