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 installer s attention to Ar ticle 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.

5.2. Equipments
·Color Analyzer CA-210.
·Video Pattern Generator Chroma2329.
·Color TV Pattern Generator PM5418/Fluke5418.
·VGA cable , AV(RCA) cable ,YPBPB (RCA) cable, HDMI cable etc.
5.3. ADC Calibration
5.3.1. Signal and generator
PC: Chroma2329 Pattern 42,Timing 14(1024X768@60Hz 5 MOSAIC)
YPBPR: Chroma2329 pattern 103, Timing 79(100% Color Bar,720p)
5.3.2. Steps of Calibration:
1). Access to the Factory menu->ADC

2). select RGB source and see the 5 MOSAIC appear on the screen
3). Select AUTO ADC , Press the right button on the your remote to
calibrate the ADC automatically.
4). Select YPBPR source and Repeat step 5.3 .
When the OK appears the calibration has been finished successfully.
5.4. White Balance adjustments (Manual)
Before adjustment ,you must make sure the ADC status(only PC and
YPbPr) is “success”and Color Analyzer has been calibrated .Only
AV1,YPbPr,PC,HDMI1 need to be adjusted. HDMI1 should be the first.
5.4.1. Signal and generator
The pattern of the signal should be used are White (Chroma2329
pattern 113) and Grey (pattern 114).
The format of signal are respectively 720P for HDMI1 (Chroma2329
Timing 69),PAL (Chroma2329 Timing38) for AV1,1024X768@60Hz(Chroma2329
Timing14) for VGA and 720P(Chroma2329 Timing79) for YPbPr.
5.4.2. Steps of adjustment
1).Enter the factory menu-> White Balance, select source HDMI 1
and Normal Temperature.
2).Input grey signal in 720p format.
3).Change R-OFFSET and B-OFFSET to make sure the value of color
coordination equal to (X=0.280 +/-0.015;Y=0.290 +/-0.015).
4).Input white signal in 720p format.
5). Change R-GAIN and B-GAIN to make sure the value of color
coordination equal to (X=0.280 +/-0.015;Y=0.290 +/-0.015).

6).Repeat step 2—5 until both of the value of color coordination
of white and grey equal to (X=0.280 +/-0.015;Y=0.290 +/-0.015).
For COOL and WARM color temperature, just repeat step 2—5.The
color coordination we recommend for COOL and WARM color temperature
is respectively(X=0.270 +/-0.015;Y=0.270 +/-0.015) and
(X=0.300 +/-0.015;Y=0.305 +/-0.015).
After the adjustment of HDMI1, you can switch to other source AV,
PC and YPbPr and repeat step 1—6 to do the WB adjustment.
Note: For some small size LED panel,the color coordination of
specifications is not X=0.280/Y=0.290,and we recommend you adopt the
values from panel specifications.
5.5. ADC Calibration and White Balance Adjustment (automatic)
The process of adjusting ADC and White Balance automatically is
out of the range of this file, Please refer to the relevant technical
