When your device is blinking red, this means you are in Alert Mode. To turn off the Alert Mode is going into the Silent Beacon Safety App and click the Red Alert button in the main menu. (picture here). You will be prompted to enter the 4 digit code you created when you first opened the app. (picture here).
The device is blinking Red, but App is not in Alert mode. (picture here with Alert in Red and Device image glowing red) Hold both Alert Buttons on the Beacon for 20 seconds (the color will turn solid blue) then release. The device will now stop blinking Red. Now try to reconnect to the Safety App. To avoid this in the future do not turn off your Bluetooth® while in Alert Mode. If your Beacon will not reconnect after 1 minute you may follow the reset feature here. (link here to reset instructions).
If you do not have access to your phone or the Safety App you can reset the Beacon by holding both buttons for 30 seconds (until the Beacon blinks white). Warning you will have to reset your device. (link to reset instructions)
