What to Do Before You Send the Mind Machine

Please read the User Guide (page 7) and follow the instructions to check for any common problems and how to solve them.

  1. If there is no sound in the Headphone, the cause is that the Headphone is not fully inserted in the CPU or the stereo cable is not fully inserted in the CPU or the MP3 Player. Please remove both and re-insert. If it still does not work, try some other headphone. If the other headphone also does not work, that means the problem is not with the headphone.
  2. If there is NOISE in the Headphone, the cause is a mobile phone or router for Internet near the CPU. Please keep CPU away from them.
  3. If the BLUE indicator light on the CPU is off, there can be 2 reasons
    (1) The stereo cable from MP3 Player is not connected to the CPU properly. Remove the cable and re-connect it.
    (2) Pencil cells are not correctly inserted or have no power. Remove them and reinsert new ones.
  4. If there is no blinking light in the Mind Glasses, the cause is that the Mind Glasses is not fully inserted in the CPU or the stereo cable is not fully inserted in the CPU or the MP3 Player. Please remove both and re-insert.

If it still does not work, please have someone else do these steps.

If it still does not work, please call /email us for suggestion.

And in the rare case it still does not work, send only the CPU, Glasses and Cable to us after packing nicely for repair.
