Problem Solution
The remote control
doesn’t function easily
or at all.
• Check that the batteries are loaded in the remote control or the batteries are not
weak. (See page 6.)
• Check that the remote control sensor isn’t exposed to direct sunlight or fluorescent
light. (See page 9.)
• Use the remote control within its operation range. (See page 9.)
• Use the remote control at least 10 cm away from the projector.
The buttons on the
control panel (except
for the POWER
button) don’t function.
• PASSWORD FUNCTION in the FEATURE menu has been set to MENU ACCESS to
enable the password lock.
Cancel the password lock or contact the person in charge of management of the
projector. (See page 41.)
Mechanical operating
noise (clicking sound)
is heard.
• Theirisproducessoundwhileoperating.Thisisnotamalfunction.
Abnormal sound is
heard.
• Because the color wheel spins at a high speed, metallic sounds may be heard in rare
occasions. Such symptom is not a malfunction.
Images are not 3D.
* The 3D glasses are
sold separately. They
are not supplied with
this product.
• Isthe3DintheIMAGEmenusettoON ?
Set the 3D to ON .

glasses? Or, is there a sticker or other such item on the infra-red reception section on
the 3D glasses?
The 3D glasses operate by receiving signals from the 3D emitter. Check that there
is not any block in the communication area between the 3D emitter and the 3D
glasses.
• Isthedistancebetweenthe3Demitterand3Dglassestoofar,ortooclose?
Adjust the location of the 3D emitter.
• Arethedirectionofthe3Demitterandthatoftheinfra-redreceptionsectiononthe
3D glasses misaligned?
Adjust the direction and location of the 3D emitter.
• Isthe3Dglassesturnedoff?
Turn on the power of the 3D glasses.
• Itmayneedtoswitchthe3Dmode(suchas3Dsettingsystem)oftherecorder/player
when projecting 3D images with the 3D image supporting recorder/player. (For detail,
see the User Manual of the recorder/player.)
• Isthe3Dmodeoftheprojectorsetproperlyfortheimage?
Set the 3D MODE of the projector (FRAME PACKING, SIDE BY SIDE, TOP AND

• Isthereanyother3Demitteror3Dimagesupportingtelevisionclosetothe3D
glasses?
The 3D glasses work by receiving signals from the 3D emitter. Check that there is
no interference of the signals from other infra-red emission section.
The power of the
3D glasses turns off
automatically.
* The 3D glasses are
sold separately. They
are not supplied with
this product.
• Isthereanyblockinthecommunicationareabetweenthe3Demitterandthe3D
glasses? Or, is there a sticker or other such item on the infra-red reception section on
the 3D glasses?
When the signal from the 3D emitter is interrupted, the power of the 3D glasses
automatically turns off 5 minutes after the interruption. Check that there is not any
block in the communication area between the 3D emitter and the 3D glasses.
