How To Tips

How to get a bigger sound when using the 3M™ Projector Sleeve

Do you want bigger sound when watching a video or movie? Since the 3M Projector Sleeve does not have a speaker and relies on the iPhone speaker for audio‚ and a bigger sound requires additional speakers. Your first option is standard computer speakers or self-powered speakers. Simply place the speakers into your phone’s headphone jack. Your second option is Bluetooth wireless speakers. Follow the instructions that come with the speakers to make a Bluetooth connect with your phone. Then place the speakers below or beside the image. Now you have an instant‚ spur-of-the-moment home theater.

How to Charge an iPhone 4/4s using the 3M Projector Sleeve

  1. Dock your phone into the 3M Projector Sleeve.

Note: The 3M Projector Sleeve does not mirror the phone’s screen. You must start a photo or keynote slideshow or start a video.

Watching a Video or Photo

On your Apple® iPhone 4/4S‚ start a video or photo slideshow.

Troubleshooting Notes:
  • If the projector displays a blue screen‚ your phone is not sending video to the 3M projector. Refer to the User Guide for your Apple device and look for “Watching a Video”‚ “Slideshows” and “TV out.”
  • If the iPhone 4/4S is already playing a video‚ it will not play on the projector until you stop the video and restart it.



The projector will not turn on.

  • The battery is not charged or the power adapter is not connected to the projector and a working wall outlet. First charge the battery. If the battery does not seem to charge‚ test the electrical outlet by plugging another electrical device (such as a radio) into the wall outlet and confirm that the wall outlet works.

The image is not visible or is very dim.

  • The 3M Projector Sleeve is a battery operated projector and requires controlled lighting conditions. The image may appear very dim in brightly lit rooms.
  • Project the image onto a flat‚ white surface.
  • Decrease the light on the surface where the image is being projected.
  • Decrease the size of the image.

The iPhone is docked into the projector but the projector will not display the video.

  • You must start a video‚ Keynote present or photo slideshow before it is displayed by the projector.
  • Confirm that the app has the TV-out feature. Some app restrict this feature.
  • Confirm that iPhone 4/4S recognizes the 3M Projector Sleeve by looking for “MFi Accessory” in Settings > General > About. If you do not see MFi Accessory in the About screen on the phone‚ then follow these steps: 1. Remove the phone from the projector and turn off the project; 2. Dock (or slide) the phone into the projector; 3. Turn on the projector and the phone will recognize the projector. When the phone recognizes the projector‚ MFi Accessory‚ which is the 3M Sleeve Projector‚ will appear in the About screen just above Diagnostics and Usage Statics.

The iPhone displays the message: “This accessory is not optimized for this iPhone. You many experience noise caused by celluar interference and a decrease in cellular signal strength.”

  • This is maybe caused by a communication failure between the phone and projector when you docked the phone into the projector. To avoid this message‚ turn off the projector; remove the phone from the projector sleeve; dock (or slide) the phone into the projector; and finally turn on the projector again.

The projected image appears distorted.

  • Turn off Widescreen in Setting > General > TV out on the iPhone.

The project stops showing the video after a few minute every time.

  • The iPhone may be going into lock mode. You can adjust this function in Setting>General>Auto-Lock.
