8.2Replacement of Batteries

Battery on circuit board

A lithium battery (Type CR2450-F2 ST2L, Code No. 000-144-941) fitted on a circuit board inside the processor unit preserves data when the equipment is turned off, and its life is about three years. When its voltage is low the battery icon () appears at the top of the display. When the icon appears, contact your dealer to request replacement of the battery.

WARNING

Ensure battery polarity is correct.

Wrong polarity may cause the batteries to explode.

8.3Replacement of Fuse

The fuse on the power cable protects the equipment from reverse polarity of the ship’s mains and equipment fault. If the fuse blows, find out the cause before replacing it. Use the correct fuse. Using the wrong fuse will damage the equipment and void the warranty.
