ADJUSTMENT SOFTWARE INSTALLATION
q
Boot up Windows.
- Quit all applications when Windows is running.
w
Insert the cloning software CD into the appropriate CD
drive.
e
Select ‘Run’ from the [Start] menu.
r
Type the setup program name using the full path name,
then push [Enter] key.
(For example; D:\Setup.exe)
t
Follow the prompts.
y
Program group ‘CS-F43TR ADJ’ appears in the
‘Programs’ folder of the [Start] menu.
■
BEFORE STARTING SOFTWARE ADJUSTMENT
Program the adjustment frequencies, listed in page 5-2, into
the transceiver using with the CS-F43TR before starting the
software adjustment. Otherwise, the transceiver can not
start software adjustment.
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 mem-
ory data at the same time.
■
STARTING SOFTWARE ADJUSTMENT
q
Connect IC-F43TR and PC with the OPC-478 and JIG
CABLE.
w
Turn the transceiver power ON.
e
Boot up Windows, and click the program group ‘CS-
F43TR ADJ’ in the ‘Programs’ folder of the [Start] menu,
then CS-F43TR ADJ’s window appears.
r
Click ‘Connect’ on the CS-F43TR’s window, then appears
IC-F43TR’s up-to-date condition.
t
Set or modify adjustment data as desired.
