Introduction
EXAMPLE OF ANTENNA GROUNDING AS PER THE
NATIONAL ELECTRICAL CODE
24. LASER BEAM
Do not look into the opening of the disc tray or ventilation opening of the product to see the source of the
laser beam. It may cause sight damage.
25. DISC
Do not use a cracked, deformed, or repaired disc. These discs are easily broken and may cause serious
personal injury and product malfunction.
26. NOTE TO CABLE TV SYSTEM INSTALLER
This reminder is provided to call the Cable TV system installer’s attention to Article 820-40 of the NEC that
provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be con-
nected to the grounding system of the building, as close to the point of cable entry as practical.
TO USE AC POWER SOURCE
Use the AC polarized line cord provided for operation on AC. Insert
the AC cord plug into a standard 120V 60Hz polarized AC outlet.
Notes:
• Never connect the AC line cord plug to other than the specified
voltage (120V 60Hz). Use the attached power cord only.
• If the polarized AC cord does not fit into a non-polarized AC
outlet, do not attempt to file or cut the blade. It is the user’s
responsibility to have an electrician replace the obsolete outlet.
• If you cause a static discharge when touching the unit and the
unit fails to function, simply unplug the unit from the AC outlet
and plug it back in. The unit should return to normal operation.
