3. INSTALLATION AND CONVERSION
1: Writing a frequency into PROM (Fig. 3-1)
Input an allocated frequency with the PROM writer.
5: Installing KOT-1 (Fig. 3-2, 3)
Connect plug P32 (E31-2181-05) to J32 on the
For simplex, duplex, etc. input, refer to the PROM
writer instructions.
2: To modify a 16CH transceiver for duplex, install JU14
on the PLL unit.
3: To modify a 6CH transceiver for simplex, open JU12
on the PLL unit.
4: Installing Signalling other than KOT-1, -2.
Refer to the manual supplied with the Signalling de-

7: Conversion to 16CH with KOQT-2 or without CTCSS
Disengage the front panel, remove the 6CH rotary
switch S$01-1433-05 secured to the chassis, then
10:
disconnect the rotary switch plug connected to
PLL unit J7. Install the new rotary" switch
$29-1432-05 and cable E31-2176-05 to the 16CH
revision kit PC board. Secure the rotary switch to
the chassis and connect the cable plug P9 to PLL
unit J9. Cut off the brown and red wires from the
plug, since these two wires are not used.
: Conversion to 16CH with KQT-1
The only difference from item 7 is that cable plug P9
is now connected to CTCSS unit J31.
Cable: E31-2182-05
: Conversion to 32CH without signalling or CTCSS
Basically the same as in item 7. Use the 32CH revi-
sion kit in lieu of the 16CH kit and connect the brown
and the red leads (cut in item 7) to the S2 AUX switch
on the TX-RX unit, as shown.
