If you need to move the Alert Button to another location or re-configure it to use another WiFi network, you need to clear it of old WiFi information first. How is it done?

Use a phillips screwdriver and remove 4 screws from the top of the yellow cover. You will see a battery holder on one side of the push switch and a green circuit board on the other. The circuit board has two small push switches as shown here:

Press and hold the CLEAR button. Then, while keeping the CLEAR button depressed, press the TEST button. After a few seconds, you will see a steady blue light at the bottom of the Alert Button. It indicates that your device has been cleared of WiFi information. Let go of both buttons. Your Alert Button is ready to be configured with a new WiFi network.
