4. CLONING OPERATION

------------------------------------------------------------------------------

Programmed data can be cloned to an IC-M710 instantly.  All data is clone

sent (PC -> TR) or clone read (PC <- TR).  A cloning cable, OPC-478 is

necessary to connect a PC's RS-232C port and the transceiver. 

For convenience, when changing a small portion of the programmed contents, 

clone read the data from the transceiver, modify the data, then clone send 

it back to the transceiver. 

CLONE SEND (PC->TR)

The programmed data in the PC is copied to the transceiver.

1) Connect the OPC-478 between the PC's RS-232C terminal and transceiver's 

   [CLONE] jack.

2) Turn the PC and transceiver power ON.

3) Start up this program.

4) Select "Clone" in the TOP menu with the [C] key, or an [Arrow] and 

   [Enter] keys.
