SECTION 5 ADJUSTMENT PROCEDURES
5-1 PREPARATION
When adjusting IC-F24/F25/S, the optional CS-F14 ADJ
ADJUSTMENT SOFTWARE
(Rev. 1.0 or later), JIG cable (see the illust
below) and OPC-478 (RS-232 type) or OPC-478U (USB type)
CLONING CABLE
are required.
REQUIRED TEST EQUIPMENTS
SYSTEM REQUIREMENTS
• Microsoft
®
Windows
®
98/SE/ME/2000/XP
• RS232C/USB port
BEFORE STARTING SOFTWARE ADJUSTMENT
Clone adjustment freqencies, TX power, CTCSS frequency,
DTCS code and IF bandwidth (see
ADJUSTMENT
CONFIGULATION
on the next page) into the transceiver
using with the CS-F14
CLONING SOFTWARE
before starting
SOFTWARE ADJUSTMENTS. Otherwise, the transceiver
can not be adjusted.
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
memory data at the same time.

STARTING SOFTWARE ADJUSTMENT
(1) Connect IC-F24/F25/S and PC with OPC-478/U
and JIG CABLE.
(2) Turn the transceiver power ON.
(3) Boot up Windows, and click the program group 'CS-F14 ADJ’
in the ‘Programs’ folder of the [Start] menu, then CS- F14
ADJ’s window appears.
(4) Click ‘Connect’ on the CS-F14’s window, then appears
IC-F14’s up-to-date condition.
(5) Set or modify adjustment data as desired.
