Hi, Here are a few tips for connecting Bluetooth speakers. If your Bluetooth audio device has been previously paired with several other devices, it may have trouble pairing to the projector initially. Unpair the Bluetooth audio device from all other devices and then pair again with the projector. You may need to reset the pairing setting on the Bluetooth audio device and then verify it is in pairing mode. It may take several attempts for the pairing to occur. Note: To protect digital copyrighted content sent to the projector, your Epson projector is HDCP-compliant (High-bandwidth Digital Content Protection) and can only pair with Bluetooth audio devices that support SCMS-T (Serial Copy Management System-Transfer) protection. Check with the manufacturer of your Bluetooth audio device for SCMS-T compatibility. Regards, Mark - The Epson Team.
