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.
