1. Remove the 14 screws affixing the top and bottom
covers of repeater, and remove the covers (Figure 1).
2. Turn the repeater upside down.
3. Referring to Figure 2, remove the upper screw
in either 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 bottom 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 supple-
mental mounting brackets supplied with the CT-
68 Hardware Kit (Figure 4).
6. Connect the optional Antenna Cable CT-68 be-
tween the TX antenna jack of the repeater and
ANT (center) jack of the duplexer.

7. If your repeater's Tx/Rx frequency relationship
is "upper shift" type (TXf > RXf), connect the
coaxial cable from the RX Unit to the LOW PASS
jack of the duplexer 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 co-
axial 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.
