Press down on the battery pack to be sure contacts on
the battery pack engage properly with contacts in the
charger.

correctly connected.
Do not place the charger in an area of extreme heat or
cold. It will work best at normal room temperature.
The battery pack may become slightly warm to the touch

problem.

on until the battery pack is removed from the charger or
charger is disconnected from the power supply.
To remove the battery pack from the charger, depress
latches and pull up on the battery pack.
When the battery pack is fully charged, remove it from
