BEFORE STARTING SOFTWARE ADJUSTMENT

Clone the adjustment frequencies into the transceiver, and-
set the confi guration using with the CS-F70/F1700 

CLONING 

SOFTWARE

 before starting the software adjustment. Other-

wise, the transceiver can not start software adjustment. 

CAUTION!:

 BACK UP

 the originally programmed mem-

ory data in the transceiver before program-
