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.

But it must be set to 0 before delivery: Select the Init Value item, then press ▶
button to set FACTORY MODE to 0.
ALIGNMENT PROCEDURE
1. Adjustment in VGA mode:
1) Required equipment: 2225 Signal Generator.
2) Connect the power adapter and generator, and press POWER button to switch the unit
on.
3) Press “PC Input” button to switch to VGA mode.
4) Input
1024 x 768 @ 60 Hz, Chessboard pattern signal. Enter Color Setting in Factory
Mode, and select Auto Adjust. to calibrate ADC to standard state.
5) Make sure the color is OK in these modes: 640×400 (60Hz) , 720×400 (60Hz), 640×480
(60Hz), 800×600 (60Hz), 1024X768(60HZ).
2. Auto adjustment of White Balance:
1) Auto adjustment in VGA /HDTV mode:
Required equipment: Color analyzer Chroma7120, Specific series port interface
HDTV signal generator.
A. Input 720p, Full White signal from Chroma7120.
B. Switch to HDTV mode, and press PRESETS button to set the picture mode to
standard.
C. Confirm the baud rate of the Colour analyser is 9600(unlock the lock key—red led on is
locked, and select the RS-232 key, the row 1 in the display screen will display the baud rate, you can
press the number key to change the value.). After setting, press the lock key to lock the baud rate.
D. Enter the Factory Mode.
Select cool or standard or warm. Then enter the sub menu to select Y item, and
measure Y with the colour analyser and adjust it to a needed value (about 100cd/㎡in VGA mode,
250 cd/㎡). Then select AUTO item, and activate the auto adjustment.
1. Adjustment
in VGA mode 2, 3. Adjustment of White Balance
4. Check the
setting in the
Factory mode

2) Auto adjustment in TV/AV mode:
A. Switch to AV mode.
B. Input the Gray Scales signal.
C. Set the picture mode to Standard.
D. Enter the Basic Setting of Factory Mode to adjust Blacklight until the second dark
scale is just visible.
E. Change the input signal to H/2 White Reference signal and enter the Factory Mode.
Set Y to 250 cd/㎡, the method is same to that in VGA/HDTV mode.
3. Manual adjustment of white balance
1) VGA/HDTV mode
A. Select HDTV mode, then press PRESETS key in remote control to select Standard
picture mode.
B. Input H/2 White Reference signal, then adjust white balance.
a. Cool color temperature: select cool in factory menu, and revise R, G, B gain value until
x=276±15, y=286±15.
b. Standard color temperature: select standard in factory menu, and revise R, G, B gain
value until x=284±15, y=299±15
c. Warm color temperature: select warm in factory menu, and revise R, G, B gain value
until x=305±15, y=320±15.
2) AV/TV mode
A. Select AV mode, then press PRESETS button to select Standard picture mode.
B. Input the Gray Scales signal and adjust Blacklight in factory menu until the second
dark scale is just visible.
C. Input
H/2 White Reference signal, then adjust white balance.
The method is same as above.
Note: If the EEPROM is fire-new, the values are set to default after powering on. In normal
condition, it needs just a little adjustment on the base of default values.
4. Check the setting in the Factory mode:
1) Basic Setting:
