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.

CEA CHILD SAFETY NOTICES:  Flat panel displays are not always supported on the proper stands or
installed according to the manufacturer’s recommendations.  Flat panel displays that are inappropriately
situated on dressers, bookcases, shelves, desks, speakers, chests or carts may fall over and may cause
personal injury or even death.
The consumer electronics industry (of which Panasonic is a member) is committed to making home
entertainment enjoyable and safe. To prevent personal injury or death, be sure to follow the following safety
guidelines:
TUNE INTO SAFETY:
•One size does NOT fit all. Follow the manufacturer’s recommendations for the safe installation and use
of your flat panel display.
• Carefully read and understand all enclosed instructions for proper use of this product.
• Don’t allow children to climb on or play with furniture and television sets.
• Don’t place flat panel displays on furniture that can easily be used as steps, such as a chest of drawers.
• Remember that children can become excited while watching a program, especially on “larger than life”
flat panel displays.  Care should be taken to install the display where it cannot be pushed, pulled over,
or knocked down.
• Care should be taken to route all cords and cables connected to the flat panel display so that they
cannot be pulled or grabbed by curious children.
WALL MOUNTING: IF YOU DECIDE TO WALL MOUNT YOUR FLAT PANEL DISPLAY, ALWAYS:
• Use a mount that has been recommended by the display manufacturer and/or listed by an independent
laboratory (such as UL, CSA, ETL).
• Follow all instructions supplied by the display and wall mount manufacturers.
• If you have any doubts about your ability to safely install your flat panel display, contact your retailer
about professional installation.
• Make sure the wall where you are mounting the display is appropriate.  Some wall mounts are not
designed to be mounted to walls with steel studs or old cinder block construction.  If you are unsure,
contact a professional installer.
• A minimum of two people are required for installation.  Flat panel displays can be heavy.
The American Academy of Pediatrics discourages television viewing for ch\
ildren younger than 
two years of age.
