You
can use the Volume buttons on 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 can also
control the volume for Bluetooth audio devices 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.
Note: To
adjust the volume of a connected audio/video system, set the
HDMI Link setting to On and the Audio
Out Device setting to AV
System in the projector's Settings menu.
- Turn on the projector and start a presentation that includes audio.
- To raise or lower the
volume, press the
volume up or 
volume down button on the
projector remote control.
Note: If you lowered the streaming device volume all the way using the Android TV remote control, you must first raise the volume using the Android TV remote control, and then adjust the volume using the projector remote control.
