• There could be ultrasound interference from an environmental source. Click here for information on testing for environmental interference.
• Try replacing the battery in the stylus pen with a new battery.
• There may be an ultrasound sensor failure in the Mimio device. Click here for information on testing for a failed ultrasound sensor.
• If you have another Mimio device available, try calibrating to see if you can isolate the issue to that specific device.

There are two generations of Mimio wireless. Each has a different form factor for the wireless USB receiver, also referred to as the wireless dongle. The latest Mimio wireless has a wireless receiver with a flash drive form factor, while the first generation Mimio wireless used a small black box for a wireless receiver that connected to the computer with a short mini-B USB cable.

NOTE: The wireless components from the first generation Mimio wireless are not compatible with the components from the 2nd generation Mimio wireless.

Flash drive form factor (dongle)

Plugs into your computer’s USB port and should have a solid green LED light

Click here for more information.

NOTE: A solid green LED identifies that the wireless USB receiver is receiving power, but it does not indicate a successful wireless pairing. The wireless module connected to the Mimio Xi device has two LEDs at its base. The top LED has a radio tower icon next to it—this is the wireless link status indicator, and it should be solid green (indicating a wireless link with the receiver). If the link status LED is flashing or amber, there is no connection with the wireless receiver and it may require re-pairing.The bottom LED has a pen icon next to it, which is the pen activity indicator. When a wireless link is established, this LED will flash when in an idle state; it will turn solid green when a Mimio stylus is in use. This LED will not light up.

1. Confirm the same version of Mimio wireless components are being used together, i.e. DMA-02-03 and DMA-02-03M work together as do DMA-02-02 and DMA-02-02M. You cannot mix these. Also, confirm both components have the same 2-digit version number. This info can be found on the label on both wireless components.
2. Unplug wireless receiver from USB port and connect into a different USB port.
3. On the wireless receiver/dongle, depress the small button with the tip of your fingernail, pen tip, etc. until LED begins flashing (~4 seconds).
4. Within 30 seconds, depress the recessed button beneath the power LED on the Mimio Xi device for 1 second until you hear a beep.
5. If you are successful re-pairing the Mimio wireless components, the wireless link status LED on the Mimio Xi should turn to solid green.

Small black box form factor (dongle)

1. There is no LED on the black box. You must stick a paperclip in the small hole on the flat face of the box and hold for 1 second.
2. Within 30 seconds, depress the recessed button beneath the power LED on the Mimio Xi device for 1 second until you hear a beep.
3. If you are successful re-pairing the Mimio wireless components, the wireless link status LED on the Mimio Xi should turn to solid green.
4. The 2-digit revision code on black box must match the 2-digit revision code on the wireless module on the Mimio Xi device. You must remove the wireless module from the Mimio Xi device to view the revision code.

1. Make sure all sensors on the Mimio device have a clear line of sight to the writing surface and pens.
   1. The infrared sensor (IR) is the black semicircle protruding from the side of the bar.
   2. Two ultrasound sensors (US) are on the side of the Mimio device at the top and bottom of the bar. They appear as small silver circles.
   3. Make sure nothing is blocking these three sensors.
2. Make sure the Mimio device is facing the proper direction. The Mimio bar should have the infrared and ultrasound sensors facing towards the writing surface.
3. Enter the calibration screen.
   1. Three options:
      • Touch the interactive stylus pen to the writing surface and it will bring up the calibration screen (first time only).
      • Push the bottom of the five buttons (for Xi) and top botton (for Teach) on the Mimio device until the calibration screen appears.
      • Open Mimio Notebook and select Tools > Settings > Interactive > Calibrate for Windows, or select Notebook > Preferences > Interactive > Calibrate for Mac.
   2. Using the Mimio Interactive mouse, press on the center of each of the nine calibrations points that appear on the projected image on the writing surface.
   3. Once completed, your Mimio device is now ready to use in Interactive Mode.

NOTE: You can save your calibration by opening Mimio Notebook and selecting Tools > Settings > Interactive from the pull down menus and check the Use previous calibration option.

1. Complete an environmental test. Click here for instructions.
2. Touch a Mimio stylus pen about an inch in front of the top ultrasound sensor on the Mimio device (this looks like a small silver circle on the side of the Mimio device). When touching down the pen, verify if the pen indicator LED on the Mimio device turns green.
3. Do the same for the bottom ultrasound sensor.
4. If the pen indicator LED on the Mimio device does not turn green when each test is performed, there is a dead ultrasound sensor which requires warranty service. NOTE: A dead or weak ultrasound sensor can only detect a stylus pen when positioned directly in front of it.
5. Contact Mimio Technical Support for warranty service instructions.

NOTE: If available, always verify if another Mimio device works in place of the original device.

Yes, it is possible to connect a wireless USB receiver into a USB hub.

AC power is only required for Mimio wireless if battery power is not preferred. When connected to a computer via USB cable, the device is powered by the computer through USB and does not require external power.

• When using Mimio interactively with a projector, select the pen tool and appropriate color from the Mimio Tools to record handwritten notes.
• You should not be using the Capture Kit pens with dry-erase markers when using Mimio interactively. Set the ink stylus pens aside and only use the Mimio Mouse interactive pen when using Mimio interactively with a projector. It is an incorrect setup to use ink pens with a projected image.

Verify that the ultrasound sensor is functioning correctly. Click here for information on checking for a failed ultrasound sensor.

• When connected to the computer via USB or powered with AC power, the Mimio device will always stay on.
• To power down the Mimio device, the AC adapter or USB cable must be unplugged from the Mimio device.
