Replacing the Fuse
A 2.0A fuse protects the switch’s power supply unit from power surges. In
case of a power surge, the fuse will burn out, thus cutting off the connection
and preventing high voltages from reaching the power supply or the other
sensitive parts of the device. The fuse, and a spare one, are contained in a
fuse case located just beneath the AC power connector. When replacement
becomes necessary, pry open this case with a small screwdriver and replace
the damaged fuse. You may also purchase a new 2.0A fuse, which is readily
available in most local stores.

WARNING! DO NOT defeat the purpose of the fuse by
using a jumper (such as a wire) in place of a
damaged one. Doing so may cause serious
damage to the switch.
