Replacement procedure
Handling Precautions
• Replace with the lithium battery set (model No.: 81446431-001).
The lithium battery set can be ordered from Azbil Corporation.
• When removing or mounting the RAM board or battery con-
nectors, do not use metallic tools. Doing so might short-circuit
electrical circuits.
• While the battery is removed for battery replacement, the capaci-
tor on the RAM board backs up the contents of memory.
As this capacitor is charged, make sure that the controller is left
ON for at least 1h before replacing the battery. Insert the new
battery on the RAM board within 24h of turning the controller
OFF.
When the BAT LED starts blinking, follow the procedure below to
replace the battery.
(1) Leave the controller turned ON for at least 1h.
(2) Turn the power OFF.
(3) Remove the key cover from the console, and fully loosen the
lock screw under

grounded metal object to remove any static electricity from your
body.
