THIS SYMBOL INDICATES THAT THERE
ARE IMPORTANT OPERATING AND
MAINTENANCE INSTRUCTIONS IN THE
LITERATURE ACCOMPANYING THE
APPLIANCE.
WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE
TO RAIN OR MOISTURE.
1. Read instructions - All the safety and operating instructions should
be read before the appliance is operated.
2. Retain Instructions - The safety and operating instructions should
be retained for future reference.
3. Heed Warnings - All warnings on the appliance and in the operat-
ing instructions should be adhered to.
4. Follow Instructions - All operating and use instructions should be
followed.
5.
Cleaning - Unplug the unit from the wall outlet before cleaning.
Do not use liquid cleaners or aerosol cleaners. Use a damp cloth
for cleaning.
EXCEPTION: A product that is meant for uninterrupted service
and, that for some specific reason, such as the possibility of the loss
of an authorization code for a CATV converter, is not intended to be
unplugged by the user for cleaning or any other purpose, may
exclude the reference to unplugging the appliance in the cleaning
description otherwise required in item 5.
6. Attachments - Do not use attachments not recommended by the
unit manufacturer as they may cause hazards.
7. Water and Moisture - Do not use this unit near water - for exam-
ple, near a bath tub, wash bowl, kitchen sink, or laundry tub, in a
wet basement, or near a swimming pool, and the like.
8. Accessories - Do not place this unit on an unstable
cart, stand, tripod, bracket, or table. The unit may
fall, causing serious injury to someone, and serious
damage to the appliance. Use only with a cart, stand,
tripod, bracket, or table recommended by the manu-
facturer, or sold with the unit. Any mounting of the
appliance should follow the manufacturer’s instructions and should
use a mounting accessory recommended by the manufacturer. An
appliance and cart combination should be moved with care. Quick
stops, excessive force, and uneven surfaces may cause the appliance
and cart combination to overturn.
9. Ventilation - Slots and openings in the cabinet and the back or bot-
tom are provided for ventilation and to ensure reliable operation of
the unit and to protect it from overheating, and these openings must
not be blocked or covered. The openings should never be blocked by
placing the unit on a bed, sofa, rug, or other similar surface. This
unit should never be placed near or over a radiator or heat register.
This unit should not be placed in a built-in installation such as a
bookcase or rack unless proper ventilation is provided or the manu-
facturer’s instructions have been adhered to.
10. Power Sources - This unit should be operated only from the type of
power source indicated on the marking label. If you are not sure of
the type of power supply to your home, consult your appliance deal-
er or local power company. For the units intended to operate from
battery power, or other sources, refer to the operating instructions.
11. Grounding or Polarization - This unit is equipped with a polar-
ized alternating-current line plug (a plug having one blade wider
than the other). This plug will fit into the power outlet only one
way. This is a safety feature. If you are unable to insert the plug
fully into the outlet, try reversing the plug. If the plug should still
fail to fit, contact your electrician to replace your obsolete outlet.
Do not defeat the safety purpose of the polarized plug.
12. Power-Cord Protection - Power-supply cords should be routed so
that they are not likely to be walked on or pinched by items placed
upon or against them, paying particular attention to cords at plugs,
convenience receptacles, and the point where they exit from the
appliance.
13. Outdoor Antenna grounding - If an outside antenna or cable sys-
tem is connected to the unit, be sure the antenna or cable system is
grounded so as to provide some protection against voltage surges
and built-up static charges. Article 810 of the National Electrical
Code, ANSI/NFPA No. 70, provides information with respect to
proper grounding of the mast and supporting structure, grounding of
the lead-in wire to an antenna discharge unit, size of grounding con-
ductors, location of antenna-discharge unit, connection to grounding
electrodes, and requirements for the grounding electrode. (Fig. A)

Lightning-For added protection for this unit receiver during a
lightning storm, or when it is left unattended and unused for
long periods of time, unplug it from the wall outlet and discon-
nect the antenna or cable system. This will prevent damage to
the unit due to lightning and power-line surges.
