3. Select AV, press “OK” to enter, press the return key to exit, and return to the main interface of the projector. 

Note：

1. Make sure to connect the AUX cable to the connector marked "AV" on the projector, if it is connected to the "headphone" connector on the left by mistake, the connection will fail and no sound will come out of the projector.
