MAINTENANCE1. METHOD OF REPLACING BATTERY
Complete steps (1) to (3) within 30 minutes.
If the battery is left removed for a long time, the memory
would lose the contents.
If there is a danger that the replacement cannot be
completed within 30 minutes, save the whole contents of the
CMOS memory to a memory card. The contents of the
memory can be easily restored with the memory card in
case the memory loses the contents.
Discard the dead battery, observing appropriate municipal rules and
regulations. When discarding the battery, insulate the terminal with a tape
so that no short–circuit would occur.
