Suppose you must move the Non-contact Liquid Level Alert to another location or re-configure it to use another WiFi network. In that case, you need to delete the information already stored there. To do that, follow the steps below:

1. Using a Phillips screwdriver remove the four screws holding the lid and remove it
2. Remove one battery, wait 5 sec, and insert battery back into clips
3. Make sure that there is no blue light on the chip inside
4. Locate and push the Clear (button 1) button. This button needs to be held depressed when device is activated to wipe WiFi configuration

A float sensor, sometimes called a float switch,  is a device that is used to sense the level of a fluid. It acts as a mechanical switch. There is a float ring surrounding the sensor. When the float is at the bottom, the switch is open.
