What To Do
The Charge Status LED flashes amber
while the battery charging circuit evaluates
the battery as a part of the charge cycle. If
the battery is found to be OK, the Charge
Status LED will change to solid amber
while the battery is charging. The internal
battery charges any time the ventilator is
connected to an external power source. If
the battery is deeply discharged, the
Charge Status LED may flash amber for
up to an hour.
If the battery does not reach full capacity
after several charge cycles (vent should
run for more than 40 minutes on nominal
settings) replace the internal battery. See
Internal Battery Pack in Chapter 8 for
instructions.
If the battery won't charge completely after
replacing it, there may be a problem with
the charge circuit on the power board.
Replace the power board. See Power
Board Assembly in Chapter 8 for
instructions.
