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-F33G ADJ’ appears in the ‘Programs’
folder of the [Start] menu.
■
BEFORE STARTING SOFTWARE ADJUSTMENT
Program the adjustment frequencies into the transceiver
using with the CS-F33G before starting the software adjust-
ment. 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.
