Replacing the AC Fuses
A fuse may need to be replaced if the Oximeter is plugged into an electrical outlet but the
AC Power indicator is not illuminated. The Oximeter has a dual-fuse AC power input receptacle
(both AC lines are fused).
Warnings:
Before changing a fuse, turn the Oximeter off, unplug the AC power cord, and
remove the Battery as described in
Removing the Battery on page 65
.
For continued protection against fire hazard, replace a fuse only with an
identically rated fuse. See
Specifications
on page 89
Other fuses located inside the Oximeter and Battery are not user-replaceable,
and must be replaced only by CASMED-authorized Service personnel.

remove the Battery as described on page 65.
