Safety
ii
Note to Satellite TV System Installer : This reminder is provided to call the satellite TV system installer’s
attention to Article 820-40 of the National Electrical Code (NEC) that provides guidelines for proper grounding
and, in particular, specifies that the cable ground shall be connected to the grounding system of the building as
close to the point of cable entry as practical.
• Operate the receiver using only the type of power source indicated on the marking label. Unplug the
receiver power cord by gripping the power plug, not the cord.
• Do not overload wall outlets or extension cords; this can result in a risk of fire or electrical shock.
• Never insert objects of any kind into the receiver through openings, as the objects may touch dangerous
voltage points or short out parts. This could cause fire or electrical shock.
• Do not locate the antenna near overhead light or power circuits, or where it can fall into such power lines or
circuits. When installing the antenna, take extreme care to avoid touching such power lines or circuits, as
contact with them can be fatal.
• Do not attempt to service the receiver yourself, as opening or removing covers may expose you to danger-
ous voltage, and will void the Limited Warranty. Refer all servicing to authorized service personnel.
Proper Care of Your Equipment
• Always handle the satellite receiver carefully. Excessive shock and vibration can damage the hard drive.
• Unplug the receiver from the AC power outlet before cleaning.
• Always turn the receiver off, unplug it and let it sit for at least 30 seconds before moving it.
• The use of accessories or attachments not recommended by the receiver manufacturer will void the Limited
Warranty.
• Do not place the receiver in an enclosure (such as a cabinet) without proper ventilation.
• Do not stack the receiver on top of or below other electronic devices as this can cause heat build-up and
vibration.
• 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.
• 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 out-
let, disconnect the lines between the receiver and the antenna, and disconnect the telephone line. This will
provide additional protection against damage caused by lightning or power line surges.
On some TVs, the presence of fixed images for extended periods of time may cause them to be
permanently imprinted on the screen. Consult your TV user guide for information on whether this is
a problem for your TV, what operating/viewing restrictions apply to avoid this problem, and
associated TV warranty coverage.
