3. Access the microSD card and delete any existing files named FM100-00.bin or FM100-10.bin.
4. Download the latest firmware revision as noted on page 53.
5. Transfer both the new FM100-00.bin and FM100-10.bin files to the microSD card root
directory. Do not place them in a separate folder.
6. Before removing the card from the computer it is recommended to eject it using the computer’s
onscreen Eject command (usually titled Safely Remove Hardware, Eject Media, etc.).
7. Insert the microSD card back into the FLEXmax 100. Ensure the card clicks into position similarly
to the way it was previously removed. The FM100 will select the appropriate .bin file based on its
hardware configuration.
NOTE: The following steps require access to the controller and battery disconnect at the same time.
Two people may be needed.
8. Press and hold the R
ESET button with a nonconductive narrow tool. (See Figure 51. The button is
recessed inside the hole by several millimeters.)
9. While still pressing the R
ESET button, turn the battery disconnect to the ON position.
10. Still pressing the R
ESET button, watch the LED indicators on the FLEXmax 100. (See Figure 52.)
When the S
TATUS LED indicator flashes green rapidly, the programming process has started. It is
safe to release the button.

11. Within a few seconds the STATUS indicator will begin flashing red instead of green. After
approximately 10 seconds it will flash red more quickly.
12. When the update process is complete, all LED indicators will flash in sequence as in a standard
power-up routine. The internal fan will run briefly.
The firmware update process is complete.
