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 (PowerLite Pro G6870/G6970WU). • Make sure the Audio Settings option is set to the correct audio port for your video device. • 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. 224
