YAESU MUSEN CO., LTD.
NOTE:
r
While writing the firmware, do not suspend
the program running, and do not disconnect
the transceiver from the PC. If the program is
suspended or the transceiver is disconnected from
the PC, the firmware writing may not complete, and
the transceiver will not work correctly.
r
While writing the firmware, do not use the power
save mode or the screen saver in the PC.
If firmware Ver. 03.xx is incorrectly updated to the
FTA-750/FTA-550, the LCD display will not be
displayed when the transceiver is powered on. You
will need to reinstall firmware Ver. 02.xx.
The method of reinstalling is the same as “How to

the “

e) If transceiver and programmer are connected
correctly, the update program will show on the PC
display.
f) Confirm which current version firmware is installed
in the transceiver.
If the current firmware version is the same as the
