Here are some tips if you have problems with Famoco brand validation devices.

First of all, make sure the device is fully charged and you have access to a stable Wi-Fi network.

  • Note that a municipal internet network (ile sans fil or Zap) is not considered reliable.

  • Moreover, even if the device is connected to a Wi-Fi network, it doesn't mean the internet connection is strong enough. Make sure to test before your event to avoid unpleasant surprises.

Blue screen

The volume buttons should not be held down while the unit is opening. If this happens to you, close the device by holding down the power button which is on the right side of the device below the volume.

Unable to close the device

Make sure none of the buttons on the device have been held down. If a button is stuck, the unit will not be able to shut down.

The laser is not working

Make sure you have selected the NFC/LASER tab. It is normal for the laser to be disabled if you are in the Camera tab.

None of the above works

If none of the above things work, you can remove the battery from the device and put it back in place.
To do this, you must :

  • Turn off the device;

  • Unscrew the four screws that hold the battery in place;

  • Remove the battery;

  • Put it back;

  • Put back the small screws. Make sure the screws are tight enough.
