Fail to add Duet-Extra to the Avantree Audio System (Duet/Quartet/Audiplex)

If you're experiencing difficulty adding the Duet-RX wireless headphones to another Avantree 2.4G Audio System, please try the methods below and see if the issue can be fixed.

Method 1: Reboot BOTH devices.

Method 2: Re-Pair the Headphones to the Transmitter.

Turn off both the headphones and the transmitter.

Slide & hold the power switch to pair on the headphones until the LED indicator starts to rapidly flashing Blue and Red alternatively.

Turn the transmitter tower back on. Slide and hold the Power Switch for 2s until the LED indicator starts to rapidly flashing Blue and Red alternatively. Once connected, the LED indicator on the headphones and transmitter should turn SOLID BLUE.

Method 3: Clear away any potential Wireless Interference Devices.

Other wireless devices in the vicinity of the Duet may negatively affect the range. This "source of interference" can be a WiFi router, a TV box, or even a Bluetooth device.

To solve this issue, simply move either the Duet or the source of interference away; that ought to clear the problem.

Method 4: Avoid Physical Objects.

Walls, solid materials, or even human bodies can all become "obstacles" that negatively affect the device's range.

Try clearing the space between your headphones and your transmitter tower, and see if that helps.
