REQUIRED TEST EQUIPMENTS
When adjusting IC-M72, the optional CS-M72 ADJ ADJUSTMENT SOFTWARE (Rev. 1.0 or later), OPC-478 (RS-232 type) or OPC-
478U (USB type) CLONING CABLE, OPC-1028 and JIG cable (see page 5-2) are required.

STARTING SOFTWARE ADJUSTMENT
(1) Connect IC-M72 and a PC with OPC-478/U,
OPC-1028 and JIG CABLE.
(2) Turn the transceiver ON.
(3) Boot up Windows
®
, and click the program group 'CS-M72
ADJ’ in the ‘Programs’ folder of the [Start] menu,
then CS-M72 ADJ’s window appears.
(4) Click ‘Adjust’ on the CS-M72’s window, then IC-M72’s
up-to-date condition appears.
(5) Set or modify adjustment value as specified.
CAUTION!: BACK UP the originally programmed memory
data in the transceiver before programming
the adjustment frequencies.
When program the adjustment frequencies
into the transceiver, the transceiver’s memory
data will be overwritten and lose original
memory data at the same time.
