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

the threaded mounting holes in the repeater's chas-
sis. In this case, use the supplemental mounting
brackets supplied with the CT-68 Hardware Kit (Fig-

6. Connect the optional Antenna Cable CT-68 between
the TX antenna jack of the repeater and ANT (cen-
ter) 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 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.
