Motorola GP68 Operation Manual page 19

Cloning duplicates the contents of Radio 1 (master radio) into Radio 2 (slave radio).
Only current radio configuration, channels and phone numbers are copied from one
radio to another. Tuning and alignment information are not affected by cloning. You
need a cloning cable in order to perform this operation.
SCI
SCI stands for Serial Communications Interface; it is used to configure the GP68
radio and for radio to radio cloning. The SCI port is located at the side of the GP68
radio below the accessory connector.
To Clone a Radio
1. Lift the flap covering the SCI port of the master radio.
2. Insert the cloning cable jack into the SCI port.
3. Repeat steps one and two with the other end of the cloning
cable and the slave radio. This connects both the master and
slave radios.
4. Turn on the slave radio.
5. Turn on the master radio while pressing the SIG/A key.
6. The master radio will display the following message
("CLONE") if cloning can proceed, otherwise an error
message will be shown (refer to 'Error Conditions" on
page 40)
7. The slave radio displays the following message
("ProG") while it is being programmed.
If battery level If low, the slave radio will display
"rPL.bAt" and you will need to replace or recharge the
battery before repeating the procedure.
8. When cloning If completed, both radios will reset automatically.
9. Disconnect radios from the cloning cable and they are ready for operation.
Err.01 Incompatible
software.
Err.02 Timeout error.
Err.03 Master checksum
error.
Err.04 No Programmed
Channels.
NOTE: The "master" radio must be "dealer programmable," i.e., it must have
jumper R417 removed. The "slave" radio does not need to have R417 removed
for successful cloning.
Possible Cloning Error Messages
Can't clone these two.
Check cable connection. Verify slave is on.
Master needs to be serviced by dealer to
enable cloning.
If the slave, try again. If master - or slave still
won't work - see dealer.
