It may sound like a stupid thing to mention, but ensure the unit is plugged in/switched on and both the ring light is illuminated and and the iPad is charging (illustrated by the charging lightning bolt on the battery symbol). There is a switch on the ring light on the back and temperature controls so you can adjust your light accordingly. If the iPad is not charging try unplugging the USB cable from the plug and reinserting.
Whilst most of our units have built in 4/5G signal can be an issue from time to time and it is always recommended to connect to WIFI for smooth running. To do this open the settings on the iPad go to WIFI and select your desired WIFI connection.
To use your pre-configured software open the TouchPix software on the homepage.
