Outdoor Antenna Grounding:

●

If an outside antenna is connected to the receiver, be sure the 
antenna system is grounded so as to provide some protection 
against voltage surges and built up static charges.

●

Section 810 of the National Electric Code, ANSI/NFPA 
No. 70-1984, 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 
connectors, location of antenna-discharge unit, connection 
grounding electrodes, and requirements for the grounding 
electrode.

■

Object and Liquid Entry:
Care should be taken so that objects do not fall and liquids are not 
spilled into the enclosure through openings.

■

Battery Usage:
CAUTION: To prevent battery leakage that may result in bodily 
injury, property damage, or damage to the unit.

●

Install all batteries correctly, with + and - aligned as marked on 
the unit.

●

Do not mix batteries (old and new or carbon and alkaline, etc.).

●

Remove batteries when the unit is not used for a long time.

This reminder is provided to call the CATV 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 must be 
connected to the grounding system of the building,  as close to the point 
of cable entry as practical.
