Hkkn4002 Internal Duplexer Cable Kit; Duplexer (Internally Mounted); Preselector (Internally Mounted); Hln9455 Battery Revert Module - Motorola CDR500 Programming Manual

CDR700 Desktop Repeater Station

Basic Disassembly/Assembly

has separate transmit and receive antennas, a transmit
combiner/receiver multi-coupler system or a duplexer
that is not capable of being mounted inside the
CDR700 repeater housing.

HKKN4002 Internal Duplexer Cable Kit

Two (2) of the three (3) RF cables in this kit provide con-
nection between the mini-UHF RF antenna connectors
on the Professional Series transceivers and the type-N
connectors on the receiver and transmitter ports of an
internally mounted duplexer. The third cable provides
the connections between the type-N antenna connector
of the duplexer and a type-N bulkhead female on the
back panel of the CDR700 repeater housing.

Duplexer (internally mounted)

There are several duplexers available from Motorola
that can be mounted inside the CDR700 repeater hous-
ing. The internal equipment bracket has the mounting
hole pattern to accommodate these duplexers. Please
note that the minimum transmit to receive frequency
spacing is 4.5 MHz for VHF models and either 5 MHz
(444-470 MHz) or 3 MHz (above 470 MHz) for the UHF
models of the duplexer.

Preselector (internally mounted)

There are several preselectors available from Motorola
that can be mounted inside the CDR700 repeater hous-
ing. The internal equipment bracket has the mounting
hole pattern to accommodate these preselectors. Please
note that the internal equipment bracket allows
mounting either a duplexer or a preselector, but not
both simultaneously.

HLN9455 Battery Revert Module

The HLN9455 battery revert module may be mounted
in the CDR700 repeater housing. It is placed on the rear
panel of the housing. Holes are provided in the rear
panel for affixing the module to the CDR700 repeater
housing.

HKLN4121 CDR Filler Plate

The blank panel in this kit is used to fill the opening in
the front panel of the CDR700 repeater housing if an
external repeater controller is desired. These control-
lers would include typical "off-the-shelf" conventional
and trunking controllers. The kit should be used to
ensure proper flow of cooling air within the CDR700
repeater housing when an internally mounted repeater
controller is not used.

Basic Disassembly/Assembly
Unless specifically instructed otherwise,
DO NOT discard any hardware removed
during disassembly.
In order to conserve space in the packing box, the
CDR700 repeater housing is shipped completely
assembled with the fan assembly, top cover, front
panel, and power supply installed. To gain access to its
mounting holes and equipment shelves, the CDR700
repeater housing may have to be completely disas-
sembled. With the CDR700 repeater housing disas-
sembled, you can begin to install the radios and other
components before reassembling the housing.
Before beginning installation, remove all items from
the packing container and check them against the items
referenced in one of the parts lists on pages 3-1 and 3-5.
This ensures that you have received all items necessary
to assemble the CDR700 Repeater Station. Immediately
report any missing or damaged items to Motorola
Product Services.
The following steps explain how to disassemble the
CDR700 repeater housing and how to reassemble it
while installing the components (duplexer, transmit
and receive radios, repeater controller, front panel, and
top cover).
Disassembling the CDR700
Repeater Housing
The following steps cover disassembly of the repeater
housing. Refer to Figure 3-3, on page 3-5 for identifica-
tion of each part and its corresponding reference num-
ber.
1. Place the CDR700 repeater housing on a flat
surface.
Use one of the small cardboard pieces from
the packing material as a "lazy susan" to
facilitate disassembly and reassembly.

Removing the Housing Cover

1. Remove the four TT3.5, pan head Taptite
screws, located at the sides of the housing,
using a Torx T15 driver.
2. Slide the top cover back to clear the front
panel.
3. Lift the cover straight up and remove it from
the housing chassis.
