• See "Maintenance Indicators".
• Change the input signal type setting.
• Image adjustments are incorrectly set.
• When temperature inside the projector increases, the cooling fan runs
faster.
• The lamp indicator is illuminating in red.
Replace the lamp.
• Cables are incorrectly connected to the projector or the connected
equipment works improperly.
• If this happens frequently, replace the lamp.
• The lamp will eventually need to be changed.
While the remaining lamp life draws to a close, replace the lamp.
• Operate the remote control while pointing it at the projector's remote
control sensor.
• The remote control may be too far away from the projector.
• When using the ceiling-mount rotating module (AN-SV100T) and
rotating the projector, the signal transmission to the sensor may not
work depending on the rotation angle of the projector.
• If direct sunlight or a strong fl uorescent lamp is shining on the
projector's remote control sensor, place the projector where it will not
be affected by strong light.
• The batteries may be depleted or inserted incorrectly. Make sure the
batteries are inserted correctly or insert new ones.
• Is "Off" selected in "Rotate Indicator" ?
• Check the connection of the ceiling-mount rotating module (AN-SV100T)
and projector.
• The lens cover is not attached correctly.
