ADJUSTMENT SOFTWARE INSTALLATION

qBoot up Windows.

- Quit all applications when Windows is running.

wInsert the cloning software CD-ROM into the appropriate CD-ROM drive.

eSelect ‘Run’ from the [Start] menu.

rType the setup program name using the full path name, then push [Enter] key.

(For example; D:\Setup.exe)

tFollow the prompts.

yProgram group ‘CS-F50 ADJ’ appears in the ‘Programs’ folder of the [Start] menu.

STARTING SOFTWARE ADJUSTMENT

qConnect IC-F60/F61 and PC with *OPC-966 JIG CABLE. w Turn the transceiver power ON.

e Boot up Windows, and click the program group ‘CS-F50 ADJ’ in the ‘Programs’ folder of the [Start] menu, then CS-F50 ADJ’s

window appears.

r Click ‘Connect’ on the CS-F50’s window, then appears IC-F60/F61’s up-to-date condition.

t Set or modify adjustment data as desired.

BEFORE STARTING SOFTWARE ADJUSTMENT

Program the adjustment frequencies, listed in page 5-2, into the transceiver using with the CS-F50 before starting the software adjustment. Otherwise, the transceiver can not start software adjustment.

CAUTION!: BACK UP the originally programed memory data in the transceiver before progaming the adjustment frequencies.

When program the adjustment frequencies into the transceiver, the transceiver’s memory data will be overwritten and lose original mem- ory data at the same time.
