3) Use a tester to measure the voltage between the pins of the lithium battery’s connector
on the board. If the measured voltage is below 3.4V*, the battery is dead or flat.
Replace it with a new one. When removing the old battery, cut off the clamp that is
holding the battery and, disconnect the connector. Connect the new battery to the
connector and, secure it with clamp.

* When the error 49 (low battery voltage) is issued, if a voltage is 3.4V or more, it
could mean a failure of the voltage detection circuit. Mount the MPU board in the
controller, fix it securely, and turn on the power, then check again whether an error is
displayed. If an error occurs, replace the MPU board. See the next section to re-
place the MPU board.
4) Insert the MPU board in the specified slot and push it in firmly. Tighten fixing screws
