3.4 Replacement of Batteries

The GYRO CONVERTER Board (option) has a battery. The battery for the RP Board pre- serves data when the power is turned off, and its life is about five years. When the battery voltage is low, NG (No Good) appears at the diagnostic test for the RP board. When this happens, contact your dealer to request re- placement of the battery.
