The fuse (12 VDC: 10A, 24 VDC: 5A)    in the power cable protects the 
communications unit from overcurrent and reverse polarity. If the fuse blows, find 
out the case before replacing it. If it blows again after replacement, contact your 
dealer for advice. Be sure to use the correct fuse. Use of a wrong will damage 
the equipment and void the warranty. 

Use of a wrong fuse can result in damage
to the equipment.
