VOLTAGE OF EACH CONNECTOR
Voltage measurement in protect mode Because the relay signal is "L" in the protect mode, voltages of Vcc, Vs, and Va are not output. The protect mode is reset only when the power SW is turned off. Therefore, when measuring the voltage, turn off the power SW, then turn on the power by remote control. Remeasure the power supply unit protection operation. Relay signal Voltages Vcc, Vs and Va are output only when the relay signal of "CN103-3" is "H". When the microcomputer detects an abnormal voltage, these voltages are not output. ACON signal The ACON signal indicates whether or not AC is supplied. The relay signal is output when the ACON signal is "H".

INSTALLATION
INSTALLATION PRECAUTIONS
1. Installation Environment
1) Do not expose the display directly to vapor or heat. Protect the unit from rain or water. 2) The display uses glass material, and cracks easily. So, do not subject it to vibration and shock. When carrying the display, always use two peoples so that vibration and shock is not applied to the display. 3) Do not disturb the radiation of heat from the rear, sides and top of the unit. Install the unit in a well ventilated place. Use the unit within an ambient temperature range of 0C ~ 40C. 4) Displaying a static picture for a long time may burn an after-image on the screen, the same as a CRT. To prolong the life of the unit, turn off the display when it is not in use, scroll the picture, and use a screen saver. Periodically display a uniformly bright picture over the entire screen, add complimentary colors, and insert moving pictures. Use half tones and intermediate colors, if possible, because the higher the brightness, the easier burning occurs. The problem does not occur with moving pictures. 5) Do not expose the optical filter directly to the sun for a long time. The characteristics of the optical filter will change and discoloration may occur. 6) Do not wipe the optical filter with a solvent such as benzene or paint thinner. The optical filter may peel off. Wipe the surface of the optical filter with a soft, lint-free cloth such as cotton. The surface of the optical filter scratches easily so do not rub or hit it with a hard object. 7) The brightness and contrast of the PDP are still inferior to those of a CRT. Also note that the ambient light may cause the screen become white and difficult to read. Therefore, it is recommended that the ambient light be reduced. 8) Note that light from the back may adversely affect the screen. Avoid backlighting as much as possible. 9) The display may cause radio frequency interference sensors which detect low level and low frequency radiowaves. If an improperly shielded VCR or signal cable is brought close to this unit, noise may appear on the screen. To avoid this, move the unit to a new location. 10) Near infrared rays are radiated from the front of the display panel. These rays may interfere with the infrared ray remote control unit of other equipment and with infrared communication systems. In this case, change the direction of the equipment relative to the screen or move the unit away from the other equipment so that the rays radiated directly from the screen (or reflected rays, depending on the situation) have no affect on other equipment. 11) When the display is installed in a quiet room, it is recommended that a thick curtain be hung on the wall behind the display to reduce the noise. 12) Dark gray scenes may appear purplish or greenish. To avoid this, increase the brightness.

22

2. Installation Precautions
1) The support must withstand the weight of the unit. The standards of the country must be met. 2) Special care should be taken in areas where earthquakes occur frequently. (At a magnitude of six, each pipe must withstand a load of 100 to 150 kg). 3) Grounding should be performed. (Ground connected to power outlet is acceptable). 4) Sufficient passage space. 5) Installation should be performed by at least two peoples. A simple lifter should be used. 6) When carrying the unpacked unit, do not hold the Optical Filter.

You need two strong cords. (1) Attach a bracket to each hole at the rear of the display. To do this, use screw A (10mm long) to attach safety bracket A, supplied with the display, to the hole at the rear of the display. (2) Attach two brackets to the wall. To do this, use screws B (20mm long) to attach safety brackets B, supplied with the display, to the wall. To make sure that the display is stable, attach wall brackets at the same height as (or slightly lower than) the display brackets. (3) Tie brackets A and B together To do this, use strong cords to fasten the display securely to the wall.
