11.2 Replacement of Fuse
The fuse on the power cable protects the system from reverse polarity of the ship's
mains and equipment fault. If the fuse blows, find the cause before replacing it. Use
only a 3A fuse. Using the wrong fuse will damage the unit and void the warranty.
11.3 Replacement of Battery
A battery installed on the circuit board inside the display unit preserves data when the
power is turned off. The life of the battery is about three years. When the battery volt-
age is low the battery icon ( ) appears on the display. When this happens, contact
your dealer to request replacement of the battery.
Note: If you require data currently displayed, save it to a SD memory card before re-
placing the battery.
