Notes :
• To start the Firmware Programmer from KPG-49D, the
FPRO path must be set up by KPG-49D setup.
• This mode cannot be entered if the Firmware program-
ming mode is set to Disable in the Programming soft-
ware (KPG-49D).
• When programming the firmware, it is recommend to
copy the data from the floppy disk to your hard disk be-
fore update the radio firmware.
Directly copying from the floppy disk to the radio may not
work because the access speed is too slow.
