Installations
1. Remove the 14 screws affixing the top and bottom cov-
ers of repeater, and remove the covers (Figure 1).
2. Turn the repeater upside down.
3. Referring to Figure 2, remove the upper screw in ei-
ther side of the front panel, and loosen the lower screw
in either side of the front panel, then slide the front
panel forward slightly.
4. Remove the coaxial cables connected to the TX and
RX antenna jacks of the repeater.
5. Install the duplexer into the compartment on the bot-
tom side of the repeater, using the four screws and
antenna cable provided in the CT-68 Hardware Kit
(Figure 3). Some duplexers may not line up with the
threaded mounting holes in the repeater's chassis. In
this case, use the supplemental mounting brackets sup-
plied with the CT-68 Hardware Kit (Figure 4).
6. Connect the optional Antenna Cable CT-68 between
the TX antenna jack of the repeater and ANT (center)
jack of the duplexer.

7. If your repeater’s Tx/Rx frequency relationship is “up-
per shift” type (TXf > RXf), connect the coaxial cable
from the RX Unit to the LOW PASS jack of the du-
plexer and connect the coaxial cable from the PA Unit
to the HIGH PASS jack of the duplexer.
If your repeater’s Tx/Rx frequency relationship is
“lower shift” type (TXf < RXf), connect the coaxial
cable from the RX Unit to the HIGH PASS jack of the
duplexer and connect the coaxial cable from the PA
Unit to the LOW PASS jack of the duplexer.
Note: Route the TX coaxial cable from the PA Unit as
far as possible from the RX coaxial cable from the RX
Unit.
8. Duplexer installation is now complete. Replace the
front panel back into place, and replace the top and
bottom covers.
