amount of work. To use the automatic Tune-Up™, place the battery
pack in the charger and leave it for at least 8 hours. The charger
will cycle through the following modes.
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.
USING THE MANUAL TUNE-UP™ MODE
The manual Tune-Up™ mode equalizes or balances the individual
cells in the battery pack allowing it to function at peak capacity. This
mode takes up to 8 hours to complete. Battery packs should be
tuned up weekly or after 10 charge/discharge cycles or whenever
the pack no longer delivers the same amount of work.
1. To tune up your battery pack, place the battery in the charger
as usual. The red light will blink continuously indicating that the
charge cycle has started.
2. Press the Tune-Up™ Mode button any time after the charge
cycle has started. The red light will stop blinking momentarily,
blink quickly 3 times, and then resume blinking continuously.
The charger is now tuning up the cells in your battery.
3. When the Tune-Up™ mode cycle is complete, the light will stay
on continuously. The pack is fully charged and may be used at
this time or left in the charger.
4. If you select Tune-Up™ Mode and then change your mind,
remove the battery from the charger. After 5 seconds, insert the
battery into the charger. The normal charge cycle will begin.

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 deter-
mine if the charger is OK. If the new pack charges correctly, then
the original pack is defective and should be returned to a service
