Chapter 5
Motorcycle Radio Installation
This chapter covers the motorcycle radio installation. The motorcycle radio installation is not applicable
for APX 4500/APX 1500 radios and O9 control heads.
5.1
Motorcycle Radio Description
The motorcycle model includes all the same components in the standard radio, with the exceptions
listed in the model charts in the Enhanced Single Band Mobile Radio Basic Service Manual
(MN005718A01).
5.1.1
Transceiver Enclosure
The transceiver is mounted in the weather-resistant enclosure that consists of a bottom housing and a
hinged top cover.
The top cover has a locking latch that requires a key to open. The enclosure is mounted above the rear
motorcycle wheel, oriented so that the lock is forward and the hinged cover opens toward the rear of
the motorcycle. The bottom housing has a grommeted hole for cable entry and weep holes to permit
water drainage.
The enclosure is mounted on the motorcycle with a universal mounting plate and shock and vibration
isolators. A large, braided ground-strap (installed between the mounting plate bolts and the motorcycle
frame) grounds the transceiver.
5.1.2
Control/Display Unit
All radio functions, except push-to-talk (PTT), are activated from the weather-resistant control head.
The control head and the external speaker are mounted for easy access near the center of the
handlebars. The control head is positioned for unobstructed viewing, and it may be tilted on the
horizontal axis for ease of viewing. The microphone cable port on the front of the control head is
plugged and is not used.
5.1.3
Control Head Cable
The control-head cable connects the control head to the transceiver.
The cable is routed along the motorcycle frame and has weather-resistant connections at both ends.
Excess cable is coiled under the transceiver inside the weather-resistant enclosure.
Each end of the cable is strain-relieved with jackscrews at the control head and the transceiver.
The cable is shielded to reduce the effects of radio frequency interference and ignition sense noise.
