FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installa-

tion. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance

with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interfer-

ence will not occur in a particular installation. If this equipment does cause harmful interference to radio or television recep-

tion, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference

by one or more of the following measures:

¥ Reorient or relocate the receiving antenna.

¥ Increase the separation between the equipment and the receiver.

¥ Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

¥ Consult the dealer or an experienced radio/television technician for help.

SAFETY NOTICE

USE ISOLATION TRANSFORMER WHEN SERVICING

High Voltage limiter circuit operation check.

1. Turn off TV and connect jig as shown in Figure 2. Adjust

jig fully counter-clockwise for minimum resistance.

2. Set the AC input to 120V AC and turn on TV.

3. Confirm test pattern on CRT is a usable picture, then

slowly adjust jig until the picture disappears and TV shuts

down.

4. When the limiter circuit is operating properly, High

Voltage will be less than 31.5 kV at 1.5mAwhen TV shuts

down.

5. Turn off set immediately after checking circuit operation.

6. Unplug set for one minute to reset shutdown circuit.

Remove jig and voltmeter.

CUSTOMIZED PICTURE AND SOUND ADJUSTMENTS

SET UP

Your HITACHI Projection TV has three color projection tubes: one for red, one for green, one for blue. When mixed together in the

proper proportion, the output of these three color tubes can produce any color. To produce these colors, however, the beams must be

precisely aligned over each other so that the colors can be mixed. The process of aligning these picture beams is called ÒconvergenceÓ.

Over a period of time, the picture tubes can drift out of alignment due to normal bumps and vibrations or moving the TV. If you move

your TV, or if, after a time, you notice color rings or halos around objects in the picture, you may want to converge (align) the colors.

Properly converged, the lines appear white, which is actually a combination of the outputs of the three color tubes. The output of the

green tube is stationary. The outputs of the red and blue tubes can be adjusted. When properly aligned, the outputs of all three tubes

should be directly over each other to produce the white lines.

To simplify convergence, HITACHI incorporates a feature to allow you to display a test pattern of 1 horizontal and 1 vertical line at the

center of the screen. Simply use the remote control to adjust the red and blue colors to match the green. When properly aligned, the

outputs of all three tubes should be directly over each other to produce the white lines.

To enter this adjustment mode, you may also select CONVERGENCE ADJ. from the Set Up menu. However, this will display a message

prompting you to press the front panel CONVERGENCE ADJ. button.

NOTES: 1. Only a momentary press of the CONVERGENCE ADJUST button is necessary to enter CONVERGENCE ADJUST

mode.

2. The color being adjusted will blink (red or blue) to indicate color you are adjusting.

3. To save your adjustment data into memory, press the front panel CONVERGENCE ADJUST button. If you do NOT

wish to save your adjustment data into memory, turn the TV OFF. When the TV is turned ON again, your old

convergence data will be restored.
