Charge Indicators
This charger is designed to detect certain problems that can arise,
Problems are indicated by the red light flashing at a fast rate, If this
occurs, re-insert the battery pack into the charger. If the problem
persists, try a different battery pack to determine if the charger is
working properly. If the new pack charges correctly, then the original
pack is defective and should be returned to a service center or other
collection site for recycling. If the new battery pack elicits the same
trouble indication as the original, have the charger and the battery pack
tested at an authorized service center.
HOT/COLD DELAY
This charger has a hot/cold delay feature: when the charger detects a
battery that is hot, it automatically starts a delay, suspending charging
until the battery has cooled. After the battery has cooled, the charger
automatically switches to the pack charging mode. This feature ensures
maximum battery life. The red light flashes long, then short while in the
hot/cold delay mode.
