CHARGING A BATTERY
operation time becomes too short to be useful, it is time to replace the battery.
9. If "CHARGE" and "POWER" lights on the AC adaptor/charger start flashing, remove the
battery and then reattach it. If after several attempts both lights continue to flash, this
means your battery cannot take a charge and must be replaced with a new one.
The "CHARGE" light will not light if a hot battery is attached to the AC adaptor/charger.
Attaching an extremely hot battery to the adaptor/charger is not recommended; it should be
allowed to cool down before being attached.
10. Do not short the battery's terminal.
11. Do not attempt to disassemble or modify the battery. There are no user serviceable
parts inside.
12. Throwing the battery into a fire or exposing the battery to excessive heat - over 149ºF
(65ºC) could be hazardous.
13. Be sure to set the "POWER" switch to the "OFF" position before removing the battery.
