Data Retrieval; Charging; When Is Charging Required - Ectosense NightOwl Healthcare Professional Manual

5.4 Data retrieval

Recordings performed in the Online Mode do not require further data retrieval.
Recordings performed in the Offline Mode are stored internally on the sensor and require further data
retrieval. This data download is to be performed over BLE and requires a qualified smartphone or tablet
app.
Whether data is still present on the sensor can be checked by turning the device on: if a short green light
does not immediately appear, data is still available for downloading.
NightOwl® Diagnostic System
Ectosense provides the Ectosense Healthcare Professional Android smartphone/tablet app to download
data stored on the Sensor over a BLE 5 connection.
Downloading data over the smartphone will automatically clear the memory of the sensor afterwards.

5.5 Charging

5.5.1 When is charging required?

The sensor requires at least 10 hours of recording capacity before it can start to record data. If the battery
does not meet that criterium, the sensor will emit a continuous purple light and should be charged.
When fully charged, the battery of the sensor lasts at least 30 hours.
We recommend that you advise your patients to recharge the sensor after each (nightly) recording. Doing
so ensures that the sensor is returned to you in a state that does not require recharging before dispensing
it to another patient, and can save valuable time to the operator.
While in Online Mode, battery depletion will break the connection with the smartphone app.
In Offline Mode, battery depletion will end the recording but all data will remain stored on the memory
of the sensor. A small recharge will subsequently be required prior to being able to download the data off
the sensor.
To preserve battery and battery storage capacity, in Offline Mode the sensor will automatically shut down
after 10 hours.
