BATTERY CARE
SST-442

CHARGING
The handheld is powered by a rechargeable battery,
which fits into the radio case (see FIG-1).
The battery pack can lose its charge during storage
and shipment, and should be fully charged before the
radio is used. Thereafter, the battery should be
charged overnight after each day of use, to ensure
peak radio performance for the next day. Using the
cube charger (model BC-A), the battery should
charge completely in 12 hours.
To charge the battery using a RITRON cube charger -
plug the charger cord into the smaller of the two jacks
on top of the radio. Then plug the cube into a 110
VAC outlet. The green lamp lights while the battery is
charging, and should go off only when the cube is
unplugged.
Two charger contacts, visible through the bottom of
the radio case, allow the battery to be charged using
an optional RITRON drop-in charger (model BCC-
PS). The battery pack may be charged inside or
outside of the radio case.
To charge the battery using a drop-in charger (model
BCC-PS) - plug the drop-in charger into a 110 VAC
outlet. Set the portable or battery into the charger.
Each battery contact must rest on a charger contact
pin.
NOTE: A new battery must be cycled (charged and
discharged) several times before it will reach
its maximum charge capacity.
PRECAUTIONS
•
Use only RITRON-supplied chargers; other
chargers might cause fire, explosion, or other
damage to the radio.
•
Do not "fast-charge" a brand new battery pack.
Otherwise, the battery might be damaged.
•
Once the battery has been charged fully using
the normal rate, the fast rate may be used
thereafter.
•
Do not fast-charge a battery pack that is fully
charged. This can shorten battery life.
•
Do not charge or replace a battery in an
explosive atmosphere. Contact sparking can
ignite an explosion.
•
Do not dispose of a battery in fire. An explosion
might result.
•
Do not charge the battery in temperatures colder
than about 45
°
F. Electrolyte leakage can occur
and ruin the battery.
•
Charging in temperatures above approximately
95
°
F will not harm the battery, but can reduce its
charge capacity.
