5.1 PROTECTIVE 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 damageto
the set and preserve the integrity of peripheral equipment, sensors and switches are provided for protective functions. Cooling iscon-
ducted 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
thestand-by mode.
