Tool Connect will give you an alert indicating your smart device battery has a low level of charge. The alert will prompt you to change security settings to ensure you do not have an interruption in your DEWALT Bluetooth battery usage.

If the Disable Out of Range feature remains active for any connected DEWALT Bluetooth battery when the smart device battery dies, you will lose Bluetooth® connectivity and the product will be disabled.
