Upgrading: When upgrading the firmware, if the status of the sensor in the App is
“Upgrading…” for a long time, please press the screen and pull down to reload the page and
refresh the status, because sometimes the App is not able to refresh by itself.
Calibration after Position Change: After setting up the WiFi, floor calibration should be
performed in order to use the fall detection feature. Every time after the position or angle
of the sensor is changed, the calibration should be performed again, otherwise the fall
detection will not work properly.
Cannot Find Device: At any time, each Sentinare activity sensor can only connect to one
device or App via Bluetooth. Sometimes if your Sentinare App gets a Bluetooth-out-of-range
error when trying to connect to a Sentinare sensor, please make sure the sensor is not
currently connected to other device or App via Bluetooth. Sometimes the other device
could be your cell phone. To check if this is the case, please go to the phone’s Settings >
Bluetooth page. If the sensor is connected in this page, please turn off the phone’s
Bluetooth to stop the connection, then turn on the Bluetooth, and connect to the sensor
from the Sentinare App again. You can also factory reset the device to disconnect its
Bluetooth link.
Duplicate Alert Prevention: To test the various alert features of the system, please set the
“Duplicate Alert Prevention” in the Setting page to be “None”, such that every alert will be
sent to the App. In addition, please turn off the “Delay Fall Alert” in the sensor page, such
that an alert will be sent immediately after a fall is detected, without waiting for 30
seconds.
General Error Recovery Procedure: If the App behaves unexpectedly or stops responding,
please force close the App using the following methods for iOS and Android respectively,
and then restart it.

If the sensor behaves unexpectedly or stops responding, please follow the following
procedure:
o Restart the sensor from the App.
o If the problem persists, power down and power up the sensor again.
o If it still does not work, remove the sensor from the account, and re-add it.
o If the problem still cannot be resolved, please perform a factory reset. If Bluetooth
connection with the sensor is available, the factory reset can be done via the App.
Otherwise physical factory reset can be done via the reset hole in the back of the
