Table 1-9 and Table 1-10 show the physical dimensions
and weight of these units. Figure 1-1 shows a com-
pletely assembled CDR500 repeater using a Basic
repeater controller. Figure 1-2 shows a completely
assembled CDR700 repeater using a Basic repeater
controller.
CDR500 Repeater Housing
The CDR500 repeater housing provides mounting for
the units that make up a customer's individually tai-
lored wall-mounted repeater station. The CDR500
repeater is shipped from the factory with the fan
assembly and the power supply already installed in the
repeater housing. To ensure proper orientation when
the CDR500 repeater is mounted on the wall, the
repeater components (radios and controllers) should
be assembled upside-down.
CDR700 Repeater Housing
The CDR700 repeater housing provides mounting for
the units that make up a customer's individually tai-
lored, free-standing repeater station. The CDR700
repeater is shipped from the factory with the fan assem-
bly and the power supply already installed in the
repeater housing. Before you can assemble the CDR700
repeater, the housing must be partially disassembled as
described in Section 3 of this manual.
CDR500 Repeater Fan Assembly
A fixed-speed (2800 rpm), continuously operating 12
Vdc fan is provided for cooling the assembled CDR500
repeater. The fan operates at an air flow rate of approx-
imately 100 cfm.
CDR700 Repeater Fan Assembly
The fixed-speed (1900 rpm) 12 Vdc fan assembly is
mounted onto the rear wall of the CDR700 repeater
housing chassis. It keeps the equipment from overheat-
ing and causing malfunctions. A thermal switch from
the power supply is connected to the heatsink on the
underside of the transmit radio and monitors the tem-
perature of the radio. The fan turns on when necessary.

CDR500 Power Supply

The CDR500 repeater 's power supply HPN9005 or
HKPN4001 operates from a 115/230 V ac operates from
a (switch selectable) power source. The power supply
provides power to the fan assembly, both radios, and
up to two repeater controllers. Battery backup/revert
with trickle charging is a standard feature of the
CDR500 repeater's power supply. The power supply
has three connectors:
