Do not place the charger in an area of extreme heat or
cold. It will work best at normal room temperature.
NOTE: The charger and battery pack should be placed in
a location where the temperature is more than 50°F but
less than 96°F.
The battery pack may become slightly warm to the touch
while charging. This is normal and does not indicate a
problem.
After charging is complete, the green LED will remain on
until the battery pack is removed from the radio/charger
or charger is disconnected from the power supply.
NOTE: Always remove the battery pack from the radio/
charger before unplugging the unit from a power source,
or before plugging the unit into a power source.
To remove the battery pack from the charger, depress
latches and pull up on the battery pack.
When the battery pack is fully charged, remove it from
the charger.
OPERATION
CHARGING A HOT BATTERY PACK
When using a tool continuously, the battery pack may
become hot. A hot battery pack may be placed directly onto
the charger port but charging will not begin until the battery
temperature cools to within acceptable temperature range.
When a hot battery pack is placed on the charger, the red
LED will begin flashing and the green LED will be off. When
the battery pack cools to approximately 120°F (40°C), the
charger will automatically begin charging.
CHARGING A COLD BATTERY PACK
A cold battery pack may be placed directly onto the charger
port but charging will not begin until the battery temperature
warms to within acceptable temperature range. When a cold
battery pack is placed on the charger, the red LED will begin
flashing and the green LED will be off. When the battery
pack warms to approximately 32°F (0°C), the charger will
automatically begin charging.
