Controlling the Volume with the Volume Buttons
You can use the Volume buttons on the remote control to adjust the volume as you project a
presentation with audio. 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.
1. Turn on the projector and start a presentation that includes audio.
