ADJUSTMENT FREQUENCY DATA
Before starting the adjustment, back up the original frequen-
cy data and program adjustment frequency data at right
using the optional programming software (EX-2057 Rev. 1.0
or later for IC-F310/F320, CS-F300S for IC-F310S/F320S),
cloning cable (OPC-478), and adaptor cable (OPC-592) for
your convenience.

TRIMMER ADJUSTMENT
When you adjust the contents on page 5-4, TRIMMER ADJUSTMENT, the optional EX-2057, OPC-478 and JIG CABLE are
required.
• STARTING TRIMMER ADJUSTMENT
Turn the transceiver power ON, connect a computer to the [MIC] jack using the optional OPC-478 CLONING CABLE and JIG
CABLE, then start up the "ADJUST" program in EX-2057 or CS-F300S.
•
STARTING THE PROGRAM
q Boot up DOS.
w Insert the EX-2057 or CS-F300S backup disk into drive A.
e Type the following to start up the program:
ADJ>ADJUST [/A : /B]*
1
[/1 : /2]*
2
[Enter]
• The adjustment screen appears after reading set data
from the transceiver.
r After the adjustment screen appears, set or modify the
data as desired.
*
1
PLL reference crystal type.
/A: Normal crystal type. (You must select [/A] for IC-
F310/F310S/F320/F320S’s adjustment.)
/B: This does not activate for IC-F310/F320’s adjust-
ment.
*
2
RS-232C port number.
NOTE: When the EEPROM (FRONT unit; IC3) is replaced or the transceiver displays an error message and beeps, the
following operation is necessary before starting the ADJUSTMENT.
1. Download the programmed data using the EX-2057 or CS-F300S from an exact same version of the transceiver, then
save it. (See the instructions for detailed operation.)
2. Set the cursor to the [MODEL] and push the [
↓] key on the computer keyboard.
3. Type "RESERVE" then push [Enter].
"Reserved" indicator flashes at the right hand, top corner on the computer screen.
4. Connect the transceiver which has been repaired, then write the data to the transceiver.
