NOTE: The MicroFID II will not operate without the charging connector cap in place.
NOTE: The MicroFID II will not operate with the AC Adapter plugged into the MicroFID II.
Repeat Charging with an AC Charger
If the AC charger has been plugged into an electrical outlet and has been used to charge a FID, and
another charging operation is to be performed, please remove the charger from the unit and wait until the
status LED on the charger changes from either
green or red to orange before plugging it into the second
unit.
NOTE: The status change will take up to 15 seconds and the orange LED indicates that the unit
is ready to start a new charge cycle.
CAUTION: If the AC charger is not properly reset according to the above instructions, it is
possible that the AC charger will remain in trickle charge mode and the FID battery will not
receive a full charge. This will limit the FID’s operating time and may cause problems in lighting
the FID flame due to low voltage.
Filling the Hydrogen Fuel Cylinder
The MicroFID II hydrogen fuel cylinder is a metal hydride design that requires relatively low hydrogen
pressure to fill it.
