You
can use the Volume buttons on the
projector or the remote control to adjust the volume of your
projected content. The volume buttons
control the projector’s internal speaker system or any external
speakers you connected to the projector.
You must adjust the volume separately for each
connected input source.
Warning: Do
not start playback at a high volume. Sudden loud noises may cause
hearing loss. Always lower the volume before turning off the
projector. Gradually increase the volume after turning the
projector on.
