ADJUSTMENT SOFTWARE INSTALLATION
q
Boot up Windows.
- Quit all applications when Windows is running.
w
Insert the ‘CS-F30G’ into the appropriate drive.
e
Select ‘Run’ from the [Start] menu.
r
Type the setup program name using the full path name,
then push [Enter] key.
(ex. D:\CSF30GADJ\disk1\Setup.exe)
t
Follow the prompts.
y
Program group ‘CS-F30G ADJ’ appears in the ‘Programs’
folder of the [Start] menu.
■
STARTING SOFTWARE ADJUSTMENT
q
Connect IC-F40GT, F40GS, F41GT or F41GS and PC
with *OPC-966
JIG CABLE
.
w
Turn the transceiver power ON.
e
Boot up Windows, and click the program group ‘CS-F30G
ADJ’ in the ‘Programs’ folder of the [Start] menu, then
CS-F30G ADJ’s window appears.
r
Click ‘Connect’ on the CS-F30G’s window, then appears
IC-F40GT, F40GS, F41GT or F41GS’s up-to-date condi-
tion.
t
Set or modify adjustment data as desired.
• High power transmittion
When you adjust the output power (high power), the battery
type detector must be connected to GND (see illustration at
below). Otherwise the transceiver does not transmit high
power, the output power will be low.
