Outdoor use Do not install this unit outdoors. If the unit is exposed to rain, it may result in fire or electric shock. If the unit is exposed to direct sunlight, the unit may heat up and it may damage the unit. Vehicle and ceiling Do not install this unit in a vehicle or hung from the ceiling.

Outdoor Antenna Grounding
If an outdoor antenna is installed, follow the precautions below. An
outdoor antenna system should not be located in the vicinity of overhead
power lines or other electric light or power circuits, or where it can come
in contact with such power lines or circuits.
WHEN INSTALLING AN OUTDOOR ANTENNA SYSTEM,
EXTREME CARE SHOULD BE TAKEN TO KEEP FROM
CONTACTING SUCH POWER LINES OR CIRCUITS AS CONTACT
WITH THEM IS ALMOST INVARIABLY FATAL.
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 Electrical Code (NEC) in USA and Section
54 of the Canadian Electrical Code in Canada 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.

For added protection for this television receiver 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. This will prevent
