9 EXTERNAL SPEAKER INSTALLATION (OPTIONAL)
The radio has a built-in speaker on its front panel. If a speaker external of the radio is required, install it in
according to the following procedure. Total available speaker cable length is approximately 10 feet
(308 centimeters). Therefore, to include service loops in these cables, the speaker must be mounted within
approximately 9.5 feet (290 centimeters) of the radio.
1. Select a location for the speaker that will allow for proper listening range with a moderate volume
setting.
2. Install the speaker using the hardware and mounting bracket supplied with it. For the speaker’s part
number, see Table 5-2 (page 24).
3. Route the speaker cable to the rear of the radio.
4. Connect the Option Cable 14002-0174-08 (item 3 in Table 5-2) to the DB-44 connector on the rear of
the radio. Tighten the cable’s two (2) jackscrews securely. See Section 11.1 for additional information
on this cable.
5. Mate the Option Cable’s 2-pin connector (identified P2) to the 2-pin connector on the end of the
speaker cable. A mild click will be sensed to confirm proper mating.
6. Route the cables out of the way of casual contact. Tie and stow as necessary.
10 MICROPHONE ATTACHMENT
There are several versions of microphones available for use with the radio. Each has a 12-pin connector
that mates with the mic connector on the front panel of the control head. A microphone clip is included
with each microphone. The radio can be configured to provide a monitor function when the microphone is
cradled in the clip. Connect the mic to the control head and install the clip as follows:
1. Position the mic’s connector just in front of the control head’s mic connector so it can engage straight
into the mic connector. The small notch on the end of the mic’s connector must be positioned straight
up so it engages with the key in the connector of the radio.
2. Mate the two connectors by pressing them fully together. A click should be sensed when the
connectors latch together.
3. Using the microphone clip as a template, drill mounting holes in the surface of the selected location.
4. Select a mounting surface location that has clearance for the mic when it is clipped to the clip, and
then attach the microphone clip to the surface. Use self-locking hardware (i.e., machine screws with
washers and locking nuts), self-drilling screws, or other appropriate hardware as necessary. Tighten
securely. The microphones have integrated hookswitches. Therefore, the microphone clip does not
require grounding.
5. Clip the microphone to the clip.
