Installing the Transmit Radio

IMPORTANT
Before installing the radios into the
CDR500 Repeater Station connect the RF
and repeater cables.
1. Place the radio/duplexer bracket on a flat sur-
face with the open end down.
2. Remove the cover gasket from the accessory
connector of the transmit radio.
3. Locate either the 30-80517U05 or 30-80517U11
cable (depending upon the duplexer option).
4. Connect the mini-UHF end of the cable to the
antenna connector of the transmit radio. Refer
to Figure 2-4 on page 2-4.
5. Connect one end of the first repeater cable to
the accessory connector of the transmit radio.
6. Place the transmit radio, upside-down, at the
bottom (open end) of the bracket. (The rear of
the radio must be on the same end of the
bracket that contains the slotted tabs for
mounting the bracket into the CDR500
repeater housing.) Position the radio to align
the holes of the radio with the M5 holes of the
housing.
7. Attach the transmit radio to the bracket with
two M5 x 0.8 x 8 T25 Torx, pan head, machine
screws.
NOTE
DO NOT yet tighten the screws.

Installing the Receive Radio

1. Remove the cover gasket from the accessory
connector of the receive radio.
2. Locate either the 30-80517U10 or 30-80517U07
cable (depending upon the duplexing option).
3. Connect the mini-UHF end of the cable to the
antenna connector of the receive radio. Refer
to Figure 2-4 on page 2-4.
4. Connect one end of the second repeater cable
to the accessory connector of the receive radio.
5. Place the receive radio, upside-down, in the
middle position of the bracket (directly above
the transmit radio). Position the radio to align
the mounting holes of the radio with the M5
holes of the bracket.
6. Attach the receive radio to the bracket with
two M5 x 0.8 x 8 T25 Torx, pan head, machine
screws.

Assembling the CDR500 Repeater Housing
NOTE
DO NOT yet tighten the screws.
NOTE
If an external duplexer is being used with
the CDR500 repeater station, skip to the
next section "Installing the Antenna
Cable(s)".
Examine the duplexer that was ordered for
the CDR500 repeater model being assembled.
If four of the mounting holes contain Pemnuts
(threaded inserts), proceed to Step 3. If no
Pemnuts are present, continue with Step 2.
Using a pair of needle nose pliers, place Tin-
nerman clips from kit HKKN4002 over four of
the mounting holes of the duplexer (refer to
Figure 2-5).
Tinnerman Clip
Figure 2-5. Duplexer, Bottom View
NOTE
The threaded side of each clip should be
on the connector/tuning screw side of
the duplexer.
Place the duplexer in the radio/duplexer
bracket with the six tuning screws facing in
the same direction as the front of the radios.
The mounting holes of the duplexer must face
upward.
Secure the duplexer to the bracket with the
four 6-32 x 1/2" T15 Torx, pan head machine
screws from kit HKKN4002.
Locate the type-N male and type-N female
bulkhead cable in kit HKKN4002.
