Antenna Installation Instructions
1. Outdoor Antenna Grounding
If an outside antenna or cable system is connected 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, Article 810
of the National Electrical Code, ANSI/NFPA 70, provides information with regard to proper grounding of
the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, connection
to grounding electrodes, and requirements for the grounding electrode.
2. 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. Do not disconnect the antenna or the
power cord during a heavy storm lighting may strike while you are holding the cable cord, causing serious
injury; turn off your LCD TV and wait for the weather to improve.
3. Power Lines
An outside antenna system should not be located in the vicinity of 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, extreme care should be taken to keep from touching such power lines or circuits as contact
with them might be fatal.

Precaution on battery use
Improper use of batteries can result in a leakage of chemicals and/or explosion. Be sure to follow the instructions
below.
<Place batteries with their terminals corresponding to the (+) and (–) indications.
<Different types of batteries have different characteristics. Do not mix batteries of different types.
<Do not mix old and new batteries. Mixing old and new batteries can shorten the life of new batteries and/or cause
old batteries to leak chemicals.
<Remove batteries as soon as they are non-operable. Chemicals that leak from batteries can cause a rash. If
chemical leakage is found, wipe with a cloth.
<The batteries supplied with the product may have a shorter life expectancy due to storage conditions.
<If the remote control is not used for an extended period of time, remove the batteries from the remote control.
