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 compatible external
speakers or headphones you connected to the projector, except those
connected to the Optical Out
port. 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: For
HDMI Link, you must use an HDMI cable that supports the CEC
standard and the connected device must also be configured. Some
connected devices or functions of those devices may not operate
properly even though they meet the HDMI CEC standard. See the
documentation supplied with the device for more
information.
