Xr16 remote to an unlisted projector

@XfinityTimothyA​ Hi. It’s a xr16. I have setup my system with external Bluetooth speakers but still can’t connect the remote to control volume. 

my projectors brand is Yaber. On calling the customer support for the projector , we were given a code,  not sure how to manually input it using a XR16 remote. Looking up with the code doesn’t work either. 

Thank you for providing those details, @user_fa5f53. Please attempt the following instructions: 

Pair the XR16 Remote to Control a TV or audio device:
1. This will allow you to control your television's power, volume and input from the XR16 remote.

- Press and hold the Voice button and give the command “program remote“. You can also get there by navigating to the Settings page, then selecting “Remote Settings“ and then “Voice remote pairing.“
2. Follow the instructions on screen to select your TV and audio devices for power, volume, and input control.
3. Aim the remote at the TV, and press the Power button. If the TV turns off, turn the TV back on and verify that the Volume and Mute buttons work.

If you are still having issues, perform a factory reset:
1. Simultaneously press and hold the i button and the Home button [house icon] until the status light on the remote blinks. This takes about 5 seconds.
2. Press Power, then Last (<- arrow), then Volume Down (-) on your remote in sequence to complete the factory reset. Once this is complete you can retry pairing your XR16 remote.
