NOTES to change the lens:  Easy job - at your own risk to man up and do it
  1. Unplug leads power/battery from your Yi camera
  2. Warning - do not touch the new lens - especially the back - with your fingers!
  3. Pop off the lens front white faceplate covers on the Yi  
  4. remove the glue which holds the existing lens - hot melt - use a sharp awl or blade tip to clear the glue - no need for any heat - be patient - the lens will now unscrew counterclockwise - make 1005 sure no dust is present to get insid ethe camera with the lens off
  5. Place this focusing chart 2-4m from the camera (or you  can simply open it on your Laptop - no need to print it - foucus on the laptop at least 5m away)
  6. Connect an HDMI cable from the Yi to your HDTV - or use the yi app
  7. Insert this lens into your Yi - red side down - slowly turn the lens ClockWise CW to find the thread - almost zero force! don't cross thread it! - it will wind CW inward  The lens must NEVER be screwed too far down onto the CCD ! take care
  8. Once you are happy with the focus - apply new hot glue
  9. Re-install the faceplate - clips in
