Information
The sound may frequently be interrupted when a Bluetooth speaker is used. Make
sure that the Bluetooth speaker and the wireless access point are on a straight line
and the Bluetooth speaker is placed as close as possible to the Projector.
To minimise interruptions, we recommend a wireless access point that uses a 5 GHz
frequency.
When the symptom persists, it is recommended to use wired connection such as HDMI
(eARC) and Optical.
HDMI (ARC) is supported by some models. Check the HDMI port name of the
purchased product's model.
