of electrical safety. While electricity is one of our greatest
friends, it can well be your worst enemy. Be sure and follow
the warnings posted in this manual and your component or
systems manuals in your owner’s packet and practice good
safety. Always have trained, competent technicians to service
your electrical systems, it could mean your life.
