Better reception

• If your headphone are picking up noise or interference, move closer to the transmitter.
• Even within the work range, there may be some “dead spots” where the RF signal cannot be received. This issue is inherent with RF signals and does not indicate a faulty product. Just slightly move the transmitter and the “dead spot” can be corrected.

If no signal or low signal for 5 minutes

• When there is no signal for 5 minutes, the transmitter will automatically power off and the transmitter POWER indicator will turn off. The transmitter will restart once the signal resumes, POWER indicator will turn BLUE.
• If the signal input from your source is too low for 5 minutes, the transmitter may also turn off. In this case, raise the volume of the audio source to a higher level but without distortion. You may then need to lower the volume on your headphone.
• If signal noise is output from your audio source, the transmitter may not turn off even though there is no audio signal.

FAQ

Use TV internal speaker at the same time with Bluetooth

This is a TV feature and its availability depends on your TV make and model. For many models of TV, the built-in speakers will either automatically mute when you plug something into an audio output port (AUX, RCA, Optical, etc.) or they become disabled once you choose “External Speakers” as your TV’s audio output. Some newer TVs allow you to play audio from both the TV’s internal speakers and an external audio device simultaneously. For example in the LG TV WebOS 3.0 / 3.5, you can enable this feature by changing the TV AUDIO OUT setting from “Internal TV Speaker” to “Internal TV Speaker + Optical”. Now all audio will simultaneously come from both your TV’s speakers and the device connected to the digital optical audio output port. If your TV does not support this feature, then you can consider the Avantree Oasis Plus + Audition Pro and an external speaker. The Avantree Oasis Plus has a convenient bypass feature which allows you to share the TV audio simultaneously with an EXTERNAL SPEAKER and a pair of Bluetooth headphones.
