3. Replacement of Battery

The processor unit has a battery which backs up the RAM contents when the power is
removed. When the voltage of the battery drops to 2.5 V, the message "BATTERY!" appears
on the screen. To check the message, press [MENU] key and choose "MESSAGE." The
lifetime of the batteries is 3 to 5 years.
Take care to avoid short-circuit of the battery. This could create a
burn or fire hazard. Do not dispose of the battery in a fire or an
incinerator; this may cause an explosion.
When the message BATTERY! appears, save the contents of the RAM onto the flash memory
temporarily as soon as possible (within about 24 hours). If the data is transferred to the flash
memory, they are not erased during the replacement.
