■ Replacement procedure
• Replace with the lithium battery set (model No.: 81446431-001). The lithium
battery set can be ordered from Yamatake Corporation.
• When removing or mounting the RAM board or battery connectors, do not use
metallic tools. Doing so might short-circuit electrical circuits.
• While the battery is removed for battery replacement, the capacitor 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
1h before replacing the battery. Insert the new battery on the RAM board within
24h of turning the controller OFF.
When the BAT LED starts blinking, follow the procedure below to replace the battery.
