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 APX Mobile Basic Service Manual (6875964M01). The following
paragraphs describe the unique items provided with the motorcycle models.
NOTE: The APX Mobile Basic Service Manual (6875964M01) includes complete parts lists and parts
numbers for all parts shown in the exploded views in this chapter.
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.

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.
See Figure 5-1.
