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.

DEBUG BOARD:
During production the Debug Board will be used to upgrading software, adjust White
Balance. The function of the board is transfer TTL Voltage to 232 Voltage. 12V DC
power supply should be provided through CON1/CON2.

T he steps of debug during production:
Manually adjustment of White Balance and ADC calibration:
1) ADC calibration
Input dual 16 grey scale signal 1024*768/60Hz(Chroma2225 Pattern47,Timing38 or
Chroma2327 Pattern47, Timing14) from VGA socket
Input 8 color bar with 100% saturation(2327 Pattern37, Timing33 or BSG360A Timing79,
Pattern85), PAL system from Y,Pb,Pr socket.
Enter ADC item of Factory Menu, select the source which you are going to calibrate.
Then select AUTO TUNE and press Vol- button in remote control.
Note: First confirm the input signal pattern and format are correct. After
calibration, If the grey scale can not be distinguished, calibrate again until it
is distinguished.
Color Temperature adjustment.
Before adjustment you should confirm the color analyzer has been calibrated. During
the process, only AV1 Y,Pb,Pr,VGA source should be adjusted. We recommend you use
CA210 color analyzer(0 channel),because it is more accurate.
Connection of devices:
1) connect CON3 of Debug Board to CA210(input VGA signal to CON6 when adjust VGA
source. Connect CON5 of Debug Board to the set through VGA cable. Input
corresponding pattern required, then select GAIN AUTO,press Vol+ button of
remote control.
2) Input 8 grey scale signal of 5418 from AV1/Y,Pb,Pr/VGA source. Point the optical
lens to the fourth brightest scale. Then enter Factory Menu and select WHITE
BALANCE page, select GAIN AUTO, press Vol+ button of remote control.
Note: In the process of adjustment, you can press MUTE button of remote control
to cancel.
