Removing and Installing a Fuse

This appendix shows you how to remove and install fuses for the VES-1012.

The VES-1012 uses two 250V-3A fuses. The VES-1012 comes with four 250V-3A fuses; two are installed at the
factory (in the fuse housing), while the two are spares that come with your VES-1012. If you need to install new
fuses, follow the procedure below.

Before you begin, you will need:

•

A small flat head screwdriver

•

250V 3A fuse(s)

•

Good lighting
