Battery management
Hub battery low: this alarm is triggered when the Hub battery capacity decreases
●
to the configured alarming limit (5%, 10%, 15% capacity left)
Charge Hub: this alarm is triggered when the Hub has 3% battery capacity left or
●
when the battery voltage drops below its low limit, whichever occurs first. If the
battery discharges completely, the Hub will shut down. Charging time for empty to
fully charged is eight hours, but may be slower at elevated temperatures.
SpO2 battery low: this alarm is triggered when the sensor battery capacity
●
decreases to the configured alarming limit (5%, 10%, 15% capacity left)
Change SpO2 battery: this alarm is triggered when the sensor battery has
●
3% battery capacity left or when the battery voltage drops below its low limit,
whichever occurs first. If the battery discharges completely, the sensor will shut
down. Charging time for empty to fully charged is five hours, but may be slower at
elevated temperatures.
Resp battery low: this alarm is triggered when the sensor battery capacity
●
decreases to the configured alarming limit (5%, 10%, 15% capacity left)
Change Resp battery: this alarm is triggered when the sensor battery has
●
3% battery capacity left or when the battery voltage drops below its low limit,
whichever occurs first. If the battery discharges completely, the sensor will shut
down. Charging time for empty to fully charged is five hours, but may be slower at
elevated temperatures.
The Hub battery life is 16 hours and that of the sensor batteries is 32 hours. However,
there are certain factors that can shorten this time — for example:
Hub: screen activity, active alarms, marginal wireless connection
●
SpO
●
2
marginal wireless connection
Respiration sensor battery: marginal wireless connection

Charging batteries

If there are indications of a battery needing charging, replace it with a fully charged
one (sensor batteries) or place the Hub in the charger if not there already. This ensures
that patient monitoring can continue uninterrupted. Return the used sensor battery
to the charger.
The Hub can be in clinical use while it is in the charger, but note that keeping the
screen on will increase the power consumption and device temperature. This may
slow down the charging, especially in high ambient temperatures. Also note that you
can charge the Hub without taking it out of the pouch.
1. If you are charging a sensor battery: disconnect the battery from the sensor.
2. Clean all device surfaces carefully as instructed in the cleaning instructions. Pay
special attention to the connection interface.
