TROUBLESHOOTING
5.1 PROTECTIVE SENSOR AND PROTECTIVE SWITCH
In event of abnormal operation due to circuit or component fail-
ure, setting error or other reason, in order to prevent serious
damage to the set and preserve the integrity of peripheral equip-
ment, sensors and switches are provided for protective func-
tions. Cooling is conducted at the same time a corresponding
LED flashes (about 10 seconds). The LED indication with respect
to the protective function is described below.
5.1.1 Protective sensor
5.1.2 Protective switch
5.2 LED (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 indica-
tors.When an LED indicates, operation (projection) automatically stops and the cool-down mode (about 10 seconds) is entered then
the stand-by mode.
O: Turned on during operation, : Blinking on during operation, Blinking time: Each time of turning on/off
