5. Connect the speaker cable’s 2-pin plastic connector to the respective mating connector on the 6-inch
speaker cable.
6. Route the cables out of the way of casual contact. Tie and stow as necessary.
In a multi-control head installation, an audio amplifier in each control head drives the
head’s speaker. Therefore, no special speakers or relays are needed.
10.2 MICROPHONE ATTACHMENT
The XL Mobile microphone is connected to the radio via a USB connector (refer to Figure 5-3).
A microphone hanger is included with each microphone. The radio can be configured to provide a monitor
function when the microphone is inserted into the hanger.
Harris mobile radio microphones and Harris mic hangers are mechanically optimized
to coexist with each other. The respective Harris mic hanger part numbers include
344A4678P1 or 14050-6015-01 for standard applications. The use of a third-party mic
hanger with a Harris microphone could potentially result in damage to the microphone
and/or inhibit normal radio operation.
Connect the mic to the Control Head and install the mic hanger as follows:
1. Plug the microphone into of the Control Heads USB mic connector.
2. Tighten the thumbscrew securely. Do not over-tighten. Use a nominal torque of 2 Nm.
3. Using the mic hanger 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 inserted to its hanger, and
then attach the microphone hanger 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 hanger does not
require grounding.
5. Insert the mic into the hanger.
Ensure the microphone is adequately protected if it could be exposed to a harsh
environment, such as water and hose-down, snow, dust, smoke, gases, road debris, oils,
chemicals and corrosive agents.
