DO NOT SHORT BATTERY PACK TERMINALS
Shorting the terminals that power to the transceiver can cause sparks,
severe overheating, burns, and battery cell damage. If the short is of
sufficient duration, it is possible to melt battery components. Do not place a
loose battery pack on or near metal surfaces or objects such as paper clips,
keys, tools, etc. When the battery pack is installed on the transceiver, the
terminals that transfer current to the transceiver are not exposed. The
terminals that are exposed on the battery pack when it is mounted on the
transceiver are charging terminals only and do not constitute a hazard.
DO NOT OVERCHARGE
Do not charge the transceiver for more than 16 hours with the battery
charge system. Heat generated by overcharging can shorten battery life
and cause other battery pack component failures. The CSA280 rapid
charger changes to trickle charge to maintain charge after their rapid
charge cycle. Battery packs may be left in the CSA280 chargers without
harm to either the battery pack or charger.
DO NOT INCINERATE
Do not dispose of any Ni-Cd battery in a fire or incinerator. The heat of fire
may cause battery cells to explode and/or release dangerous gases.
DISPOSE OF BATTERY PACKS PROPERLY
Ni-Cd batteries must be recycled or disposed of properly. For requirements
in your area, check with the dealer from whom you purchased your
transceiver. The symbol shown below is a reminder that the battery packs
are recyclable.
