• Transfer FPU Firmware
This rewrites the FPU IC program.
• If power to the camera or personal computer is cut off during the transfer,
CAUTION
the camera will no longer be able to conduct a transfer. Be sure to use a
constant-voltage power source for the camera.

Transfer FPU Firmware.
2) After communication with the camera,
the screen on the right will appear.
Use the up or down arrow key to
select the option, then press Return.
With the first communication, the exist-
ing MPU and BPU version are checked to
see whether the FPU's firmware can be
rewritten.

screen on the right will appear to indi-
cate that the transfer has been com-
pleted.
If the transfer is not possible due to MPU
and BPU being an old version, the screen
