3M™ Pocket Projector MPro150

The projector is making a noise.

•The projector has a small fan for cooling the LED light source. The fan turns on and off automatically based on the projector’s internal temperature. The fan will turn on more often in warm environments or at high altitudes.

•The speakers make noise when the volume is set to high and nothing is connected to the projector audio inputs. This is typical. Reduce the projector’s volume setting to zero.

•The speakers may make noise when the component AV cable is not correctly connected to the video device. There are two red connectors on the component AV cable. One is for the right audio channel and the other is for the Pr component video signal. If these connectors are switched, the projected image will appear green and an abnormal noise will come from the right speaker.

My video device is connected to the projector but the projector will not display the video.

•Unplug the AV cable from the projector and the home screen will display.

•Plug the VGA-audio cable into the projector and the icon in the upper-left corner of the image will display the “VGA-Audio cable” icon. See “Video Mode Icons” on page 21.

•The video output on some devices is turned off by default. Please refer to the device’s documentation for details on enabling the video output.
