11. Do not use this television set near water ... for example, near a bathtub, washbowl, kitchen sink, or laundry tub, in a
wet basement, or near a swimming pool, etc.
Never expose the set to rain or water. If the set has been exposed to rain or water, unplug the set from the wall
outlet and refer servicing to qualified service personnel.
12. Choose a place where light (artificial or sunlight) does not shine directly on the screen.
13. Avoid dusty places, since piling up of dust inside TV chassis may cause failure of the set when high humidity persists.
14. The set has slots, or openings in the cabinet for ventilation purposes, to provide reliable operation of the receiver, to
protect it from overheating. These openings must not be blocked or covered.
Never cover the slots or openings with cloth or other material.
Never block the bottom ventilation slots of the set by placing it on a bed, sofa, rug, etc.
Never place the set near or over a radiator or heat register.
Never place the set in enclosure, unless proper ventilation is provided.
15.1. If an outside antenna is connected to the television set, 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, NFPA No.
70-1975, 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 electrode, and requirements for the grounding electrode.
15.2. Note to CATV system installer : (Only for the television set with CATV reception)
This reminder is provided to call the CATV system attention to Article 820-40 of the NEC that provides
guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding
system of the building, as close to the point of cable entry as practical.
16. An outside antenna system should not be located in the vicinity of overhead power lines or other electric lights 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.
17. For added protection for this television set 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 damage due to lightning
and power-line surges.

INFO:
ªAll tests and measurements mentioned hereafter have to be carried out at a normal mains voltage
(100 ~ 240 VAC).
ªAll voltages have to be measured with respect to ground, unless otherwise stated.
ªAll final tests have to be done on a complete set including LCD panel in a room with temperature of
25+/-7°C.
ªThe White Balance (color temperature) has to be performed into subdued lighted room after at
least 1 hour of warm-up/burn-in. This is applicable for both Alignment and Picture Performance
evaluation at OQA in order to be set free of any temperature drift (colorimetry vs. time).

1.5. DDC & EDID Test
EDID data structure is according to VESA Enhanced EDID 1.3 (and EIA/CEA-861B for HDMI).
PC input and HDMI have their own separate bin files:
Check whether the correct EDID is downloaded by corresponding file checksum or read them
out bit by bit to check if it is in line with the released EDID bin file.
1.6. HDCP Test
For HDCP compliancy, it’s needed to check whether the HDCP key has been well set.
