Safety
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.
CAUTION—To reduce the risk of fire, use only No. 26 AWG or larger
telecommunication line cord.
Proper Care of Your Equipment
• Always handle the satellite receiver carefully. Excessive shock and vibration can damage the
hard drive.
• If the equipment is turned on and needs to be moved, unplug the equipemnt and let it sit for at
least 30 seconds before moving it.
• The use of accessories or attachments not recommended by the receiver manufacturer voids
the Limited Warranty.
• Do not stack the receiver on top of or below other electronic devices as this can cause heat
build-up and vibration.
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.
If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the antenna assembly.
• Increase the separation between the equipment.
• Connect the equipment into an outlet on a circuit different from that to which the DISH receiver
is connected.
• Consult the dealer or an experienced radio/TV technician for help.
