3.3 Fuse Replacement
Various fuses are used to protect the equip-
ment from overvoltage (overcurrent) or equip-
ment fault. If the fuse blows find the cause
before replacing. If the fuse blows again after
replacement, request service.
CAUTION
Use the proper fuse.
Use of a wrong fuse can cause fire or
equipment damage.

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.
