The remote control does not work after checking the batteries, why?

It is possible that the batteries are not working any more. Please change the batteries.

Reboot the LEAP AIR by unplugging the power cable located on the right side of the device.

Then, plug in the cable and turn on the device.

You must pair the remote control with the device again after the reboot. To do so, press the Return and Home buttons at the same time for 20 seconds.
