About Low Battery Detection
The Loner FDU monitors the battery level of the device. If the battery level drops below
10% of battery capacity, a Low Battery Alert will be sent and the Loner FDU will annunci-
ate the low battery alarm pattern.
The Loner FDU will continue all of the alarms until one of the following occurs:
„ The Loner FDU is powered off.
„ The Loner FDU automatically shuts down with a depleted battery.
„ The Loner FDU is plugged in for recharging.
™ The Loner FDU sends a Loner FDU Powered Off by Low Battery message via Bluetooth
to the paired smartphone before finally powering off.
Performance Expectations of the Fall Detection System:
The Loner FDU utilizes gyroscope and accelerometers to determine the motion of normal
human activity and thus determine when an extreme event, such as a fall, occurs. Accuracy
of the system depends on the user wearing the Loner FDU correctly on the belt at the hip.
