y After the installation is completed, the "InstallShield Wiz-
ard Complete" will appear. Then click [Finish].
u Eject the CD.
i The adjustment software icon appears on the desk top
screen.
▄ BEFORE STARTING SOFTWARE ADJUSTMENT
Program the adjustment frequencies into the transceiver
using with the cloning software before starting the software
adjustment. Otherwise, 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.
