22 Do not attempt to service the receiver yourself, as opening or removing covers
may expose you to dangerous voltage and will void the Limited Warranty. Refer all
servicing to authorized service personnel.
23 Unplug the receiver from the AC power outlet before cleaning.
24 Do not place the receiver in an enclosure such as a cabinet without proper ventilation.
25 Do not install the receiver in any area where the temperature can be less than 40°F or
more than 113°F. If the receiver is cold to the touch, do not plug it in immediately. Let
it sit unplugged at room temperature for at least 45 minutes before plugging it in.
26 Use an outlet that contains surge suppression or ground fault protection. During an
electrical storm or when the receiver is left unattended and unused for long periods
of time, unplug the power cord from the wall outlet, disconnect the lines between the
receiver and the antenna, and disconnect the telephone line. These actions provide
additional protection against damage caused by lightning or power line surges.
27 Tighten all of the coaxial cable connections only by hand. If you use a wrench, you
may overtighten the connections and damage your equipment.
