• Select Search Bluetooth Device in the Settings menu when you pair a Bluetooth audio device for
the first time or change to another Bluetooth audio device.
• Make sure the Bluetooth audio device is paired to the projector and not to another device.
• Make sure the Bluetooth audio device that is paired to the projector supports copyright protection

• Check the volume level on the paired Bluetooth audio device.
• Make sure there are no obstacles between the Bluetooth audio device and the projector and that the
Bluetooth audio device is within the specified communication distance. Avoid using the projector near
wireless networks, microwave ovens, 2.4 GHz cordless phones, or other devices that use the 2.4 GHz
