Indicator display

When the LAMP indicator lights, turn the power off. If the problem cannot be recovered, contact your dealer.

*1 Even when the indicator lights green, if the power supply section becomes too hot , the lamp may be automatically

turned off to cool it down (indicator continues to light green). In this case, turn off the power switch and allow the

unit to cool down before turning the power switch on again. The lamp will light. If the lamp does not light because it

is still automatically turned off, contact your dealer.

When inside temperature becomes high because ventilation holes are blocked, normally, TEMP indicator

will light red. However, to protect the projector, the lamp may be turned off and at this time LAMP

indicator may light red.
