IMPORTANT CHARGING NOTES
1. Longest life and best performance can be obtained if the DC Power Pack is charged
when the air temperature is between 65°F and 75°F (18°C - 24°C).
To prevent from damage
DO NOT
charge the DC Power Pack in an air temperature
below +40°F (+4°C), or above +105°F (+40°C).
2. The charger and DC Power Pack may become warm to touch while charging.
This is a normal condition, and does not indicate a problem.
3. If the DC Power Pack does not charge properly, (1) Check power at receptacle by
plugging in another piece of equipment, (2) Move charger and pack to a location
where the surrounding air temperature is approximately 65°F - 75°F (18°C - 24°C), (3) If
charging problems persist, take or send the equipment, DC Power Pack and charger to
an authorized Feltest service center.
4. The DC Power Pack should be recharged when it fails to produce sufficient power
enough to keep the equipment functioning properly.
DO NOT CONTINUE
to use under these conditions.
Follow the charging procedure. You may also charge a partially used pack whenever
you desire with no adverse effect on the DC Power Pack.
5. Under certain conditions, with the charger plugged in to the power supply, the
exposed charging contacts inside the charger can be shorted by foreign material.
Foreign materials of a conductive nature such as, steel wool, aluminum foil, or any
buildup of metallic particles should be kept away from charger cavities. Always unplug
the charger from the power supply when there is no DC Power Pack in the cavity.
Unplug the charger before attempting to clean.
6. Do not immerse charger in water or any other liquid.
7. For optimum performance, leave the DC Power Pack in the charger for six hours or
more once every 10 to 20 recharges. This balances the cells, keeps the pack at peak
performance and extends the usable life of the pack.
WARNING:
Do not allow any liquid to get inside charger. Electric shock may result. To
facilitate the cooling of the DC Power Pack after use, avoid placing the charger or pack
in a warm environment.
CAUTION:
Never attempt to open the DC Power pack for any reason. If the plastic
housing of the pack breaks or cracks, return the DC Power Pack to Feltest.
