except as detailed in the User’s Guide.

•

Unplug the power cord prior to opening or removing cov-
ers, or else you may be exposed to electric shock, exces-
sive temperatures, or mechanical hazards.

•

Performing service or maintenance not detailed in the
User’s Guide, with or without a Service Manual, should
only be done by a qualified service technician.

•
