Microphone
Hang-up Clip
Installation
The hang-up clip must be within reach of the operator(s). Measure this
distance before actually mounting the bracket. Since the bracket has a
positive-detent action, the microphone can mount in any position. The
microphone hang-up clip must be grounded.
Use the hang-up clip as a template to locate the mounting holes. To avoid
interference when removing the microphone, install the flathead screw in
the top clip hole.
Handheld Hang-up
Box Installation
(A3 Model Control
Head)
Use the hang-up box (HUB) as a template to locate the mounting holes.
Be sure the HUB will be within easy reach of the operator. Route the
control wire with the male pin to the accessory cable connector at the rear
of the radio or cable harness as shown in Figures 6 and 7. Open the
accessory cable connector and connect the HUB control wire to location 3
of the accessory connector. Connect the other control wire from the HUB
to a convenient solid chassis ground point.
Low-/Mid-Power
Radio Power Cable
Installation
Route the red radio power cable from the radio to the vehicle’s battery
compartment, using accepted industry methods and standards. Be sure to
grommet the firewall hole to protect the cable. Remove the 15-amp
(P/N 6580283E06) fuse from the fuseholder and connect the red lead of
the radio power cable to the positive battery terminal using the hardware
provided as shown in 8. Connect the black lead to a convenient solid
chassis ground point. DO NOT connect the black lead directly to the
battery’s negative terminal.

High-Power Radio
Power Cable
Installation
As shown in Figure 8, route the bare end of the red radio power cable from
the radio to the vehicle’s battery compartment, using accepted industry
procedures and standards. Be sure to grommet the firewall hole to protect
the cable. After the long cable has been routed to the battery compartment,
decide on a location for the fuse retainer. When choosing this location,
consider ease of checking and replacing fuses. This location should also
be as close to the battery as possible for better protection of the radio and
cabling.

NOTE:
The orange and green power cables connect to either the vehicle battery or the ignition switch. Connect the green cable directly to the battery. The receiver operates
when the control head is on. Connect the orange cable to the ignition switch. The transmitter operates only when the ignition switch is on. Alternate connections-
Connecting both green and orange cables to the battery allows the control head to turn the receiver and transmitter on or off. Connecting both green and orange cables
to the ignition switch allows the ignition switch to turn the receiver and transmitter on or off. (Alternator whine and other noise problems may occur. Isolate the green
cable with a Motorola relay, part #59-00813674.)
