CDM Control Station Installation
Additional Considerations
requirements of each installation. These levels are set with
trim pots located on the back panel of the inner chassis.
• POT1 (IC/MON)
This potentiometer allows adjustment of the Inter-
com/Parallel audio level to the internal speaker.
• POT2 (ACC RX)
This potentiometer allows the Accessory RX audio
level to be set.
• POT3 (HEADSET)
This potentiometer provides audio level adjustment
for Radio RX to the Headset.
Additional Considerations
Radio Control Head Speaker
Since the Control Station comes equipped with an internal
speaker, it is recommended that the radio speaker (located in
control head) be disabled. This is accomplished by removing
the front panel of the control head and unplugging the
speaker lead wires.
Radio Programming Parameters
The Control Station requires that several radio parameters be con-
figured to allow proper Control Station operation.

Before beginning installation, remove all items from the
packing container and check them against the items refer-
enced in one of the parts lists on page 3-7. This assures that
you have received all items necessary to assembly the Con-
trol Station. Immediately report any missing or damaged
items to Motorola Product Services.
The following steps explain how to disassemble the Control
Station housing and how to reassemble it while installing the
radio and necessary cables.

Desk Microphone
JU1 of the Desk Microphone (HMN3000) must be installed to
allow proper base station intercom operation. The jumpers
keeps the microphone circuit active at all times, thus allowing
proper base station intercom function. Instructions for install-
ing this jumper can be found in the HMN3000 Installation
Guide, 6880903Z37.
Basic Disassembly/Assembly
NOTE
Unless specifically instructed otherwise, DO
NOT discard any hardware removed during
disassembly.
In order to conserve space in the packing box, the Control Sta-
tion housing is shipped completely assembled with the fan
assembly, top cover, power supply, and control circuitry
installed. To install the radio and configure the unit, the Con-
trol Station may have to be completely disassembled. With the
Control Station disassembled, you can begin to install the
radio and configure the Interface Module before reassembling
the housing.
