Note:

This model is equipped with the lamp error detection function

that detects the current flowing into the fluorescent lamp and

protects the backlight lamp drive circuit.

If a lamp error is detected, the microprocessor interrupts the

unit and the ERROR NO RESET setting will go up.

When the ERROR NO RESET setting has reached "5", the

microprocessor turns and keeps off the unit's power. To

resume the power, take the above procedure to clear the

ERROR NO RESET setting.
