q Turn power OFF, then disconnect the DC power

cable.

w Unscrew the 4 screws, then remove the bottom

cover.

e Cut or desolder the print pattern on the PC board at

the TX mic circuit (A) and RX AF circuit (B).

r Install the unit as shown in the instruction manual.
t Replace the bottom cover and screws, then the DC

power cable.

NOTE:

Modification points are marked A or B on the circuit
board. (see corresponding figures)
A : TX modulation circuit.
B : RX AF circuit.

The scrambler unit may be installed between the mic
amplifier circuit and AF circuit. Cut or desolder the junc­tion points (or take off jumper chip for IC-F3/F4/S se­ries).

• Assign the scrambler function to a programmable key
as [SCRM] on [Key & Display Assign] screen, if re­quired.

• Operation with the [SCRM] key:

− Push and hold to turn the voice scrambler function ON.

− Push to turn the voice scrambler function OFF.

• Program the scrambler function ON/OFF and scram-

bler codes on the [Memory CH] screen, scrambler
type*, group codes*, synchronous capture mode* and
tone start timing* on the [Common] screen with
cloning software when installing this unit. (

only

)

Be sure to resolder above disconnected points, otherwise no TX modulation or AF output is available when you re­move the scrambler units.

• Some transceiver versions will not be able to

have scrambler units installed because of CPU
revision and other factors. Please confirm that
the transceivers’ serial number is over 50000.

• UT-109 and UT -110 scrambler units require some PC
board modifications. (See below.)

• There are 2 versions (#01: Low AF level type for IC­F3/F4/S series and #02: High AF level type for the
