Reference Guide (PDF Edition)

The charge lamps flash while charging is in progress and stop flashing as charging completes. Note
that depending on the batter
y charge state, there may be a delay of about ten seconds before the
lamps start flashing.
Insert the battery (terminals first), aligning the end of the battery with the guide and then sliding
the battery in the direction indicated until it clicks into place.
Leave the charger in a location where it will remain stable and free from vibration during use.
An exhausted battery will fully charge in about 4 hours.
As charging progresses, the charge lamps will light one at a time until charging is complete and all
three lamps are lit.
Battery status is shown by the charge lamps:
