If the password is incorrect, “CLONELOCK” is redisplayed. How to enter the password using the Side2 and Side3keys (K2 and K3 models);If the D key is pressed while “CLONE LOCK“ is displayed,the Read authorization password input screen (INPUTPASSWORD) is displayd.If the Side2 key or Side3 key is pressed while “INPUTPASSWORD“ is displayed, the number (0 to 9) flashes onthe LCD. When you press the D key, the currentlyselected number is determined. If you press the A keyafter entering the password in this procedure, “CLONEMODE” is displayed if the entered password is correct. Ifthe password is incorrect, “CLONE LOCK” is redisplayed.4. Power on the slave transceiver.5. Connect the cloning cable (part No. E30-3325-05) to theuniversal connectors on the master and slave.6. Press the Side1 or A key on the master while the mas-ter displays “CLONE MODE”. The data of the master issent to the slave. While the slave is receiving the data,“PROGRAM” is displayed. When cloning of data is com-pleted, the master displays “END”, and the slave auto-matically operates in the User mode. The slave can thenbe operated by the same program as the master.7. The other slave can be continuously cloned. When theSide1 or A key on the master is pressed while the mas-ter displays “END”, the master displays “CLONEMODE”. Carry out the operation in step 4 to 6.Notes: Can not be cloned if the password (over write password)is programmed to the slave.“Model Name and Market Code“ must be same to clonethe transceiver. However, it may be unable to clone thetransceiver depending on the enhanced features settings.(Refer to the FPU for the enhanced features details.)8. Self Programming Mode(K2 and K3 models only)Write mode for frequency data and signaling etc. To beused ONLY by the authorized service person maintaining theuser's equipment. After programming, reset the FPU to the“Self- Programming“ disabled mode. Transceivers CANNOTbe delivered to the end-user in the self-programming mode.The following setup items in the channels programmed bythe FPU can be changed using the self-programming mode.The addition of new channel and the deletion of channel thathas already been programmed by the FPU cannot beperformed using the self-programming mode.
