Safety Instructions

Read before operating equipment.

1. Cleaning - Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp
cloth for cleaning.

2. Power Sources - Use supplied or equivalent UL/CSA approved low voltage DC plug-in transformer.

3. Outdoor Antenna Grounding - If you connect an outside antenna or cable system to the product, be sure the antenna or cable

system is grounded so as to provide some protection against voltage surges and built-up static charges. Section 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 conductors, location of antenna
discharge unit, connection to grounding electrodes, and requirements for the grounding electrode.

4. Lightning - Avoid installation or reconfiguration of wiring during lightning activity.

5. Power Lines - Do not locate an outside antenna system near overhead power lines or other electric light or power circuits or where

it can fall into such power lines or circuits. When installing an outside antenna system, refrain from touching such power lines or
circuits, as contact with th

6. Overloading - Do not overload wall outlets and extension cords as this can result in a risk of fire or electric shock.

7. Object and Liquid Entry - Never push objects of any kind into this product through openings as they may touch dangerous voltage

points or short out parts, resulting in a fire or electric shock. Never spill liquid of any kind on the product.

8. Servicing - Do not attempt to service this product yourself as opening or removing covers may expose you to dangerous voltage or
other hazards. Refer all servicing to qualified service personnel.

9. Damage Requiring Service - Unplug this product from the wall outlet and refer servicing to qualified service personnel under the
following conditions:

 When the power supply cord or plug is damaged.
 If liquid spills or objects fall into the product.
 If the product is exposed to rain or water.
 If the product does not operate normally by following the operating instructions. Adjust only those controls that are

covered by the operating instructions. An improper adjustment of other controls may result in damage and will often
require extensive work by a qualified technician to restore the product to its normal operation.

 If the video product is dropped or the cabinet is damaged.
 When the video product exhibits a distinct change in performance, this indicates a need for service.

em might be fatal.
