■STARTING SOFTWARE ADJUSTMENT

qConnect IC-F3GT/GS and PC with the optional OPC-478 and the JIG cable.

wBoot up Windows, and turn the transceiver power ON. e Click the program group ‘CS-F3G ADJ’ in the ‘Programs’

folder of the [Start] menu, then CS-F3G ADJ’s window is appeared.

r Click ‘Connect’ on the CS-F3G’s window, then appears IC-F3GT/GS’s up-to-date condition.

t Set or modify adjustment data as desired.

■ADJUSTMENT SOFTWARE INSTALLATION

NOTE: Before using the program, make a backup copy of the original disk. After making a backup copy, keep the orig- inal disk in a safe place.

qBoot up Windows.

- Quit all applications when Windows is running.

wInsert the backup disk1 into the appropriate floppy drive. e Select ‘Run’ from the [Start] menu.

r Type the setup program name using the full path name, then push the [Enter] key. (A:\ setup)

t Follow the prompts.

y Program group ‘CS-F3G ADJ’ appears in the ‘Programs’ folder of the [Start] menu.
