Battery
fig. 27
The backup battery provides power to the RAM, where programs
and global variables are stored, and real Time Clock when the
power supply is off. You must replace it every five years. The part
number of the backup battery is CJ1W-BAT01.
To replace the battery the power must not be off for more than five
minutes to ensure no backup memory loss. If the TJ1-MC__ has
not been on, set the unit to on for at least five minutes before you
replace the battery else the capacitor that gives backup power to
the memory is not fully changed and backup memory may be lost
before the new battery is inserted.
