What does the red light at the bottom of my Loner device mean? When connected to your charger, the red flashing light indicates that your device is charging. A solid red light means that your device is fully charged. The green light on my Loner device is off, what does it mean? Your Loner device is powered off or the battery is depleted. If you press the power button and nothing happens, charge your device. My Loner device makes a single beep once every 5 minutes, what does it mean? The battery level is low. Please charge your Loner device. Why am I getting false pending Fall Detection alerts? [Fall detection](https://support.blacklinesafety.com/loner-glossary/#fall-detection) is based on acceleration. If you are working in the field and doing a lot of physical activity (i.e. jumping), your settings may be too sensitive. These settings can be adjusted on your device’s configuration profile in [Blackline Live.](https://support.blacklinesafety.com/loner-glossary/#blackline-live-(was-loner-portal)) Why am I getting false Silent Alerts? If you experience [silent alerts](https://support.blacklinesafety.com/loner-glossary#silent-emergency-alert) while driving, it may be that your seat-belt is pressing against the Silent Alert button. Consider wearing your device on your left hip. Be sure you are turning your device off using the power button and not the Silent Emergency button. Can I cancel an alert that has been sent? Once an [emergency](https://support.blacklinesafety.com/loner-glossary/#emergency-alert-(sos-alert)) or [remote alert](https://support.blacklinesafety.com/loner-glossary/#remote-alert) has been triggered, it can be silenced but not cancelled. The alert will have been sent to monitoring personnel, who will follow your organization’s emergency response protocols. ## Support Materials ### Videos Introducing the Loner M6 to Canada and the US Introducing the Loner M6 to UK and Europe Lone Worker Monitoring -
