SECTION 5 ADJUSTMENT PROCEDURES

5-1 PREPARATION

Most of adjustments must be adjusted on the adjustment mode after programmed adjustment frequency data into the transceiv-
er's memory channel. When program adjustment frequency data into memory channels, the optional CS-A23
(Rev. 1.0 or later) and OPC-478

SYSTEM REQUIREMENTS
• IBM PC compatible computer with an RS -232C serial port
(38400 bps or faster).
• Microsoft Windows 95 or Windows 98
• Intel i486DX processor or faster (Pentium 100 MHz or
faster recommended)

CLONING SOFTWARE INSTALLATION
q Boot up Windows.
- Quit all applications when Windows is running.
w Insert the cloning software CD-ROM into the appropriate
CD-ROM drive.
e Select 'Run' from the [Start] menu.
r Type the setup program name using the full path name,
then push the [Enter] key. (For example; D:\ setup)
t Follow the prompts.
y Program group 'CS-A23' appears in the 'Programs' fold-
er of the [Start] menu.
ADJUSTMENT FREQUENCY DATA
When program the adjustment frequency data into memory
channel, back up the original memory data using the cloning
software and OPC-478, and then reprogram it after adjust-
ment.
CAUTION: When program the adjustment frequency data
into the transceiver, the transceiver's memory channel will
be overwritten the data and deleted original memory data at
the same time.
ENTERING ADJUSTMENT MODE
q Turn transceiver's power off. Connect IC-A5/A23 and PC
with the optional OPC-478.
w Push and hold [Y] and [Z], then turn the transceiver's
power ON. (Displayed "CLONE" on the LCD)
e Boot up Windows, click the program group 'CS-A23' in
the 'Programs' folder of the [Start] menu, then CS-A23
window appeares.

Click the 'Advanced' tag on the 'Setting' window, then
check the 'AdjustMode Enable' check box (see the illus-
tration at page 5-2).
t Cloning the adjustment frequency data at page 5-2 to the
transceiver.
y Turn power OFF. Disconnect OPC-478 from the trans-
ceiver.
u Push and hold [MR], [CLR] and [SQL], then turn power
ON.
OPERATING ON THE ADJUSTMENT MODE
Change the channel [UP]:
Change the channel [DOWN]:
EXITING THE ADJUSTMENT MODE
When the adjustment is finished, the transceiver must be
cancelled adjustment mode to use nomal operation, other-
wise the transceiver does not work properly.
q Turn transceiver's power OFF.
w Uncheck the 'AdjustMode Enable' check box on cloning
software, and then cloning the original memory data.
e Turn power OFF.
