▄ ADJUSTMENYT SOFTWARE INSTALLATION
q Quit all applications when Windows is running.
w Insert the CD into the appropriate CD drive.
e Double-click the "Setup.exe" contained in the 'CS-F70/
F1700 ADJ' folder in the CD drive.
r The "Welcome to the InstallShield Wizard for CS-F70/
F1700 ADJ" will appear. Click [Next>].
t The "Choose Destination Location" will appear. Then click
[Next>] to install the software to the destination folder. (e.g.
C:\Program Files\Icom\CS-F70/F1700 ADJ)
y After the installation is completed, the "InstallShield Wiz-
ard Complete" will appear. Then click [Finish].
u Eject the CD.
i Program group 'CS-F70/F1700 ADJ' appears in the 'Pro-
grams' folder of the start menu, and 'CS-F70/F1700 ADJ'
icon appears on the desk top screen.
▄ BEFORE STARTING SOFTWARE ADJUSTMENT
Clone the adjustment frequencies into the transceiver, and-
set the confi guration using with the CS-F70/F1700
before starting the software adjustment. Other-
SOFTWARE
wise, the transceiver can not start software adjustment.
CAUTION!: BACK UP the originally programmed mem-
ory data in the transceiver before program-
ming the adjustment frequencies.
When program the adjustment frequencies into
the transceiver, the transceiver's memory data
will be overwritten and lose original memory
data at the same time.
