Ш ADJUSTMENT FREQUENCY DATA
When program the adjustment frequency data (at right) into
memory channel, back up the original memory data using the
adjustment program, *OPC-478 and OPC-782, and re-pro-
gram it after adjustment.
CAUTION: When program the adjustment frequency data
into the transceiver, the transceiver's memory
channel wiil be overwritten the data and deleted
original memory data at the same time.
Ш ENTERING THE ADJUSTMENT MODE
(D Connect a PC with an OPC-478 and OPC-782 to the
[SP/MIC] jack.
(2 Boot up DOS.
(3) Type the following to start up the adjustment program:
A:\>CLONE [Enter]
* Main Menu appears at the top side of the cloning pro-
gram, select the sub-menu "Edit'-"Adjust "Memory
ch", then input adjustment frequency (at right).
( Select "Write РС-» transceiv" of the Cloning on the
Main Menu.
* Application writes adjustment frequency data to the
connected transceiver.
(5) Disconnect the cloning cable, then start the adjust-
ments.

ceiver does not work properly.
(D Turn power OFF.
(2) Push and hold [FUNC] and [V/M], then turn power ON.
NOTE: All memory data except adjustment value will be cleared at this operation.
