Basically button is designed to be used inside your home with a maximal distance of 50m to its base. Theoretically you might carry it along to your workplace, so you can activate the alarm while leaving the house and turn it off when you´re coming back. Please consider that the battery consumption rises rapidly if you use your button outside of your home. Following aspects have an influence on its battery:
1. Your button will constantly try to connect with its base
2. Accidental pushing of the button consumes energy too
3. Your button will be shown as offline as long as it´s out of range
4. Your button will not react to input until it´s reconnected to base
For these reasons we recommend that you only use your button inside your home within the range of base.
