Chapter 5 Motorcycle Radio Installation

5.1 Motorcycle Radio Description

The motorcycle model includes all the same components in the standard radio. The following

paragraphs describe the unique items provided with the motorcycle models.

A small label is included with the motorcycle radio, which can be placed on the radio to identify it as

a motorcycle radio. The label should be placed on a flat and protected area to avoid damage during

handling. See Figure 5-1.

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 control head, which also is

weather-resistant. 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’s 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.
