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:

Your new Alert button needs to connect to the internet to send its alerts. They will then be forwarded as emails and as text messages to your phone. In order to do that it needs to know which WiFi network to use for communications. In addition, your Alert button must be configured with an email and phone number to send notifications. 

If you need to move the CALLME button to another location or simply need to re-configure it to use another WiFi router, there are two approaches. The simplest one is if you have an already configured and connected CALLME button. In this case, you can prepare it for the move on the "Configure Device" page: click on the  Move Device checkbox which will instruct the button to clear its WiFi configuration the next time it is pressed.  After pressing it, verify that the configuration has been cleared: when the configuration is cleared, a small blue led inside the button will light up.

The CALLME button uses proprietory circuitry to miminize battery use. It only uses it's batteries when communicating with the cloud server and confirming that the alert had been sent. The three quick blinks of the LED are that confirmation.  Based on our calculations, using the button a few times a day will not require new batteries for well over a year.
