• Avoid using the projector near wireless networks, microwave ovens, 2.4 GHz cordless phones, or
other devices that use the 2.4 GHz frequency band. These devices can interfere with the signal
between the projector and the 3D glasses.
• If the other solutions do not not solve the problem, change the
Inverse 3D Glasses
setting on the
Signal menu. Return the setting to its original value if changing it does not solve the problem.

Solutions to Sound Problems
If there is no sound when you expect it or the volume is too low or high, try the following solutions:
• Adjust the projector's volume settings.
• Press the
A/V Mute
button on the remote control to resume video and audio if they were temporarily
stopped.
• Press the
Source
button on the projector or a source button on the remote control to switch to the
correct input source, if necessary.
• Check your computer or video source to make sure the volume is turned up and the audio output is set
for the correct source.
• Check the audio cable connections between the projector and your video source.
• If you do not hear sound from an HDMI source, set the connected device to PCM output.
• Make sure any connected audio cables are labeled "No Resistance".
• If you are using a Mac and you do not hear sound from an HDMI source, make sure your Mac
supports audio through the HDMI port. If not, you need to connect an audio cable.
• If you turn the projector on immediately after turning it off, the cooling fans may run at high speed
momentarily and cause an unexpected noise. This is normal.
