TROUBLESHOOTING

5.1PROTECTIVE SENSOR AND PROTECTIVE SWITCH

In event of abnormal operation due to circuit or component failure, setting error or other reason, in order to prevent serious damage to the set and preserve the integrity of peripheral equipment, sensors and switches are provided for protective functions. Cooling is conducted at the same time a corresponding LED flashes (about 90 seconds). The LED indication with respect to the protective func- tion is described below.

5.2LED (INDICATOR) WARNING INDICATIONS

5.2.1 Led indication contents

If an abnormality occurs during operation (projection), the content of the problem can be determined from flashing LED indicators. When an LED indicates, operation (projection) automatically stops and the cool-down mode (about 90 seconds) is entered (except for No.1, No.3, No.4, No.5 and No.6), then the stand-by mode.

No.
