CHARGING A HOT OR COLD BATTERY
A steady red LED indicates that the battery is
over or under the optimal temperature. Remove
the battery pack from the charger. If the battery
is too hot, cool the battery under air flow. If
the battery is too cold, place it indoors until it
reaches room temperature.
CHARGER ERROR
If the charger self-inspection fails to react when
the charger is plugged in, the causes include no
power to the charger, bad contacts, or a charger
error. Check to see if the charger self-inspection
can be activated when the charger is plugged
in again or plugged into a different outlet. If
it still fails, have the charger serviced by an
Authorized FLEX Service Station.
WALL-MOUNT HOLES (FIG. 3)
The charger has wall-mount holes for
convenient storage. Install screws in the wall 3
inches (76mm) apart. Use screws sufficiently
strong to hold the combined weight of the
charger and battery pack.
PACK
BATTERY PACK ERROR
If the charger detects a problem, the red/green
LED will begin flashing red. Remove and re-
insert the battery pack in the charger. If the
red/green LED still flashes red, try charging a
different battery pack.
a) If a different battery pack charges normally,
have the first malfunctioning battery pack
serviced by an Authorized FLEX Service
Station.
b) If a different battery pack also indicates an
error, the charger may be malfunctioning.
Have the charger serviced by an Authorized
FLEX Service Station.
