• 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. • You must connect external speakers to the projector to hear sound (Pro L1405U/L1500U/L1505U). • Make sure the Audio Settings option is set to the correct audio port for your video device. • If you connected an audio device to the projector's Audio Out port, the internal speaker is disabled. However, you can still control the volume level via the remote control. • 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.
