■ Modification

1. Remove the cabinet and shielding cover from the trans-

ceiver.

2. Remove the panel.

3. Delete R798 and R866 on the TX-RX unit.

■ Connection

The functions of pins of CN701 on the foil side of the TX-

RX unit are shown in the figure.

Join the CN701 connector to the voice scrambler board via

the E37-0808-05 connector cable.

Note : You must setup the FPU.

The Voice Scrambler Board is connected subsequent

to the de-emphasis circuit.
