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 them might be fatal. 

 

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.

 Note to CATV system installer: This reminder is provided to call CATV system installer's 

attention to Article 820-40 of the National Electrical Code (Section 54 of Canadian Electrical 

Code, Part I), 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 possible.
