Changing a Fuse

This appendix shows you how to remove and install fuses for the MES-2110.

If you use a fuse other than an included fuse, make sure it matches the fuse specifications in the appendix on product specifications.

Removing a Fuse

Disconnect all power from the MES-2110 before you begin this procedure.

1Remove the power cord from the MES-2110.

2See the product specifications for the location of the fuse. Use a small flat-head screwdriver to carefully pry out the fuse housing.

3A burnt-out fuse is blackened, darkened or cloudy inside its glass casing. A working fuse has a completely clear glass casing. Pull gently, but firmly, to remove the burnt out fuse from the fuse housing. Dispose of the burnt-out fuse properly.

Installing a Fuse

1The MES-2110 is shipped from the factory with one spare fuse included in a box- like section of the fuse housing. Push the middle part of the box-like section to access the spare fuse. Put another spare fuse in its place in order to always have one on hand.

2Push the replacement fuse into the fuse housing until you hear a click.

3Push the fuse housing back into the MES-2110 until you hear a click.

4Plug the power cord back into the unit.
