1. METHOD OF REPLACING BATTERY
Steps 1) to 3) should be completed within 30 minutes (or
within 5 minutes for the 160i/180i with the PC function). Do
not leave the control unit without a battery for any longer
than the specified period. Otherwise, the contents of
memory may be lost.
If steps 1) to 3) may not be completed within 30 minutes,
save all contents of the CMOS memory to the memory card
beforehand. Thus, if the contents of the CMOS memory are
lost, the contents can be restored easily.
For the method of operation, refer to Maintenance manual
When discarding a battery, observe the applicable ordinances or other
rules of your local government. Also, cover the terminals of the battery
with vinyl tape or the like to prevent a short–circuit.
