NOTE:
• When starting up the projector, some small rattling or tinkling sound may be heard, or the display may flicker for the
characteristics of the lamp. Those are normal and will not affect the performance of the projector.
• When the internal cooling fan is operating, some, operational sound may be heard. The loudness of the operational sound
depends on the external temperature.
• If the projector is switched on again while the internal cooling fan is still operating by the internal power supply, it may take
a while to start the projection.
• Operating the control panel buttons with covered hand, such as plastered or gloved, may result in fail.
