When the AM-001 board was replaced, perform “Firmware Rewriting” and then make all adjustments, and finally
perform “OSD Language Setup”.

Use the AC adapter or fully charged battery whenever rewriting the firmware.
Do not remove the battery or AC adapter while the Access lamp is lighting.
Otherwise, the firmware update from the CF card will fail.

1. Copy all files in the “System” folder in the “DSLR-A100 Firmware CD” to the route directory of the CF card.
2. Turn off the POWER switch of the camera, and insert the “Firmware Update” CF in the camera.
3.  Set the AC adapter (battery).
4. Turn on the POWER switch while pressing the Lens Remove button.
5. After the Access lamp turns on, release the Lens Remove button, and the firmware update from the CF card will

start.

6. In about 2 minutes, the access lamp will turn off or blink to indicate that the update has completed.

As the camera does not operate when the firmware update completed, remove and install the battery.
