How to change the battery on the Bluetooth Safety Button?

This article will explain how to change the battery on Becklar's Bluetooth Safety Button.

Follow the steps below to replace the battery in the button:

1. Find a well-lit area and a large, flat desk or table. The screw on the back of the Bluetooth button is very small and will be difficult to replace if lost.
2. Find a Phillips head screwdriver small enough to turn the screw on the back of the Bluetooth button (2.0 mm or smaller). Pictured below is a 1.6 mm Phillips head screwdriver as an
   example.
   
3. Loosen the screw completely and remove the back cover from the Bluetooth button, exposing the battery.
4. Remove the battery and replace with a new CR2450 battery.
5. Replace the back cover and tighten the screw carefully until it is snug. Please do not overtighten.
