CHARGER INDICATOR
HOT/COLD PACK DELAY
When the charger detects a DC Power Pack that is hot or cold, it automatically starts a
Hot/Cold Pack Delay, suspending charging until the pack temperature has stabilized.
After the DC Power Pack 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 Hot/Cold Delay mode.
REPLACE PACK
The charger is designed to detect certain problems that can arise with DC Power Packs
which would be indicated by the red light flashing at a fast rate.
If this occurs, reinsert DC Power Pack. If problem persists, try a different pack to
determine if charger is OK. If the new pack charges correctly, then the original pack is
defective and should be returned to Feltest for recycling. If the
new DC Power Pack elicits the same trouble indication as the original, have charger
tested by an authorized Feltest service center.
PROBLEM POWER LINE
If the input voltage is out of tolerance, the charger may temporarily suspend
operation and begin flashing the red light (two fast blinks followed by a pause). This
indicates the power source is out of limits. If the voltage returns to an acceptable
level, the charger will automatically switch to a normal charging mode and flash
accordingly.
LEAVING THE DC POWER PACK IN THE CHARGER
The charger and DC Power Pack can be left connected with the red light glow- ing
indefinitely. The charger will keep the DC Power Pack fresh and fully charged.
