WARNING
To replace the fuse, first turn the power source OFF
and pull the power source cord out from the power re-
ceptacle, and then, replace the fuse. Attempting to re-
place the fuse without pulling the power source cord out
from the power receptacle may cause electric shock.
Moreover, check whether the fuse to replace is the same
as that prescribed in the manual, or use a fuse of the
same rating or the same properties of the fuse indicated
on the back of the MT9812B frame. Using a wrong fuse
may cause frequent fusing, burnout or fires.
