3.2 Replacement of Fuse, Battery and Thermal
Paper
Fuse
The fuse inside the receiver unit protects the equipment from overcurrent and
reverse polarity. If the fuse blows, contact your dealer about replacement.
Battery
A battery is installed on the circuit board inside the display unit, and it preserves
data when the power is turned off. The life of the battery is about 5-10 years, and
its voltage is checked when the power is turned on. When its voltage is low, the
BATT icon appears on the display to alert you. When this happens, contact your
dealer to request replacement of the battery.
Note: When the battery is dead, all default settings are restored.
