Charging Procedure - DeWalt DC390 Manual De Instrucciones

1. The red light will blink continuously indicating that the 1-hour
charge cycle has started.
2. When the 1-hour charge cycle is complete, the light will stay on
continuously and will no longer blink. This indicates that the pack
is fully charged and can be used at this time.
3. Whenever the pack is left in the charger after the initial 1-hour
charge, the charger will begin the automatic Tune-Up™ Mode.
This mode continues up to 8 hours or until the individual cells in
the battery pack are equalized. The battery pack is ready for use
and can be removed at any time during the Tune-Up™ Mode.
4. Once the automatic Tune-Up™ Mode is complete the charger will
transition to a maintenance charge; the indicator light shuts off
when the automatic Tune-Up™ Mode is complete.

Charge Indicators
Some chargers are designed to detect certain problems that can arise
with battery packs. Problems are indicated by the red light flashing at
a fast rate. If this occurs, re-insert battery pack into the charger. If the
problem persists, try a different battery pack to determine if the charg-
er is OK. If the new pack charges correctly, then the original pack is
defective and should be returned to a service center or other collec-
tion site for recycling. If the new battery pack elicits the same trouble
indication as the original, have the charger tested at an authorized
service center.
HOT/COLD PACK DELAY
Some chargers have a Hot/Cold Pack Delay feature: when the charg-
er detects a battery that is hot, it automatically starts a Hot Pack Delay,
suspending charging until the battery has cooled. After the battery has
cooled, the charger automatically switches to the Pack Charging
