Miroir projector models M200A, M300A and M631 are compatible, and come with, a bluetooth remote. These remotes can be used to control certain features of the projector itself such as volume adjustments and the input mode. More information on the remote controls can be found in the Remote Controls and Features help article if you would like additional information.
NOTE: If you are connecting a device like an AppleTV, Fire TV stick, or Roku to your projector you will be able to control the content using the remote that came with that device with any model projector.
If you are having issues with your remote, please check out the Remote Control is Not Working help article instead.
