*1: When the cooling fan is stopped and the interior becomes overheated, the power will turn off automatically to allow cooling (the indicator will turn
off). In such cases, turn off the projector power, allow the set to cool and then turn the projector power on again. The lamp will then light. If the lamp
does not light, contact your dealer or service company.
*2: In some cases, when the air holes becomes blocked and the interior temperature rises, the lamp will be turned off for protection and the LAMP
indicator will flash red. In such cases, turn off the MAIN POWER switch, allow the set to cool (for approx. 20 min.) and then turn the power on again.
