Checking Product Safety
Upon completion of any service or repairs to this product, the
service technician must perform safety checks to determine
that this product is in proper operating condition.
Outdoor Grounding System
If this product connects to an outdoor antenna or cable
system, be sure the antenna or cable system is grounded
(earthed). This provides some protection against voltage
surges and built-up static charges.
Article 810 of the National Electric Code (NEC) ANSI/NFPA
No. 70-1990, provides the following information:
• Grounding of the mast and supporting structure
• Grounding the lead-in wire to an antenna discharge unit
• Size of the grounding conductors
• Location of the antenna-discharge unit
• Connection to grounding electrodes
• Requirements for the grounding electrodes (see the
following antenna grounding diagram as recommended by
NEC ANSI/NFPA 70)
Lightning
For added protection for this product during a lightning storm,
or when it is left unattended and unused for long periods of
time, unplug it from the wall outlet and disconnect the
antenna or cable system. This will prevent damage to the
product due to lightning and power-line surges. Plugging this
product into a surge protector may reduce the risk of
damage.
Note: Unplugging this product for an extended
period of time can result in loss of authorization. For
reauthorization, contact your cable service provider.
Power Lines
