• 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 want to use a connected audio source when the projector is off, set the Standby Mode option to
Communication On and make sure the A/V Settings options are set correctly.
• If the volume for the computer is set to the minimum while the projector's volume is set to maximum,
the sound level may be mixed. Turn up the computer's volume and decrease the projector's volume
(when using Epson iProjection [Windows/Mac]).
• 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.
