TRIMMER ADJUSTMENT
When you adjust the contents on page 5-4 or 5-8, TRIMMER ADJUSTMENT, the optional CS-F3
(Rev. 3.0 or later) and OPC-478
• STARTING TRIMMER ADJUSTMENT
Turn ON power to the transceiver, connect a computer to the [SP] jack using the optional OPC-478 CLONING CABLE, then
start up the "ADJUST" program in CS-F3.
• STARTING THE PROGRAM
q Boot up DOS.
w Insert the CS-F3 backup disk into drive A.
e Type the following to start up the program:
ADJ>ADJUST [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.
NOTE:
When the EEPROM (IC7) is replaced or the transceiver displays an error message and beeps, the following oper-
ation is necessary before starting the ADJUSTMENT.
1. Download the programmed frequency data using the CS-F3
exact same version of the transceiver, then save it. (See the instructions for detailed operation.)
2. Return to DOS.
3. Copy the saved frequency data into the "ADJ" directory as follows:
A>COPY [file name].ICF A:\ADJ [ENT]
4. Connect the transceiver in which the EEPROM has been replaced, using the OPC-478 CLONING CABLE.
5. Change the directory to "ADJ", and type as follows:
A>CD ADJ [ENT]
A>ADJ>EEPROM [file name].ICF 1* [ENT]
When cloning is successful, the transceiver displays "CL GOOD".
*RS-232C port number. You have to type "A>EEPROM [file name].ICF 2" when the port number is set to "2". This setting
can be confirmed in the SETUP window while CS-F3 is running.
