3. Download the latest firmware revision as noted on page 53. Transfer the files to the microSD card.
4. If the file called
FN100-00.bin
was previously present on the card, delete it and replace it with the
downloaded file with that name. This file needs to be in the root directory, not in a separate folder.
5. 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.).
6. Insert the card back into the FLEXmax 100. Ensure it clicks into position similarly to the way it was
previously removed.
NOTE
: The following steps require access to the controller and battery disconnect at the same time.
Two people may be needed.
7. Press and hold the
R
ESET
button with a nonconductive narrow tool. (See Figure 50. The button is
recessed inside the hole by several millimeters.)
8. While still pressing the
R
ESET
button, turn the battery disconnect to the
O
N
position.
9. Still
pressing
the
R
ESET
button, watch the LED indicators on the FLEXmax 100. (See Figure 51.)
When the
S
TATUS
LED indicator flashes green rapidly, the programming process has started. It is
safe to release the button.

10. Within a few seconds the
S
TATUS
indicator will begin flashing red instead of green. After
approximately 10 seconds it will flash red more quickly.

power-up routine. The internal fan will run briefly.
The firmware update process is complete.
