The charger, to be used ONLY with the Ni-MH battery pack, starts
charging automatically as soon as a battery pack is installed and the charger
is plugged in. The LEDs on the charger indicate the condition shown in
Table3.1.
Discharge Button: Pressing the
button for approximately 2 seconds
the charger automatically
discharges the battery and switches
over to charging. The process of
discharging the battery before
charging should be performed
every three months to help prevent
loss of battery capacity due to
frequent partly discharging.
