PROTECTION AND LOCATION OF YOUR SET

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

installer s
guidelines for proper grounding and, in part icular, 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.

3.4 White Balance Adjustment

1. Input a black and white pattern to RF input.

2. Enter P-Mode, press key “3” to select white balance adjustment menu.

3. Use the color analyzer to measure the black side of the screen. Adjust the value of

“RC”,”GC” and “BC” to set the reading of the color analyzer to x=274, y=280. (11500 K).

4. Then measure the white side of the screen. Adjust the value of “RD”, “GD” and “BD” to

set the reading of the color analyzer to x=274, y=280. (11500 K).

5. Repeat step 3&4 until you can get the correct reading for both black and white sides.

Note:

A. The “SubBRI” and “SubCON” items are used to assistant the white balance adjustment.

It is the same function as the user OSD menu “Brightness” and “Contrast” items. You can

adjust these items to get the expect intensity when adjusting the white balance.

B. The “BLOR-Y”, “BLOG-Y” and “BLOB-Y” items are used for the YUV white balance
black level offset setup. When the TV white balance adjustment is done,
connect

measure the black side of the screen. Adjust the value of
“BLOB-Y” to set the reading of the color analyzer to x=274, y=280.

3.6.1 Vertical geometry adjustment

1. Input a PAL crosshatch pattern signal to RF input.

2. Enter P-Mode, press key “1” to select vertical geometry adjustment. (The OSD menu

for this adjustment as below table 3.6.1. For NTSC signal, the “-50” will be replaced with

“-60”.)

3. Adjust the value of the corresponding item to make the vertical geometry of the

pattern look good.

4. Apply NTSC signal to adjust these value for NTSC vertical geometry.

3. On producing, please use the “AUTO OFFSET” (On page “2”) function to easy the

geometry adjustment of NTSC signal. When finished the PAL signal geometry adjustment,

press “2” key to enter page “2” to select “AUTO OFFSET” item, press “” key to active the

automatic offset function. Then the geometry adjustment of NTSC signal will finish

automated. If the geometry of NTSC signal is look good, you don’t need to adjust the

geometry of NTSC signal any more.

3.6.2 Horizontal geometry adjustment

1. Input a PAL crosshatch pattern signal to RF input.

2. Enter P-Mode, press key “2” to select horizontal geometry adjustment. (The OSD

menu for this adjustment as below table 3.6.2. For NTSC signal, the “-50” will be replaced

with “-60”.)

3. Adjust the value of the corresponding item to make the horizontal geometry of the
