The operating time may be reduced due to the utilization of the battery. The data
are approximate values and cannot be regarded as guaranteed for every battery,
Replace the batteries if the operating time falls below the minimum value (see
"Battery ageing", page 15) or after 24 months.
The figures are based on the assumed following average battery usage:
– Applies to the internal battery without using the GS500:
400 battery discharges of up to 15 minutes per discharge during device
operation with the internal battery over a time period of 2 years.
– Applies for PS500 without use of the GS500:
400 battery discharges of up to 90 minutes per discharge during device
operation with the PS500 over a time period of 2 years.
The battery lifespan is shortened if the battery is discharged more frequently or for
longer than 90 minutes (PS500) or 15 minutes (internal battery). This can lead to a
deviation from the maximum operating time specified in the table above.
A discharge is defined as the usage and subsequent charging of the battery.
Preparing the battery test
The battery test can be performed independently of the operating status of the
device. If a patient is being ventilated, note the charge status indicator.
Prerequisites for the battery test while a patient is being ventilated:
– The device is connected to the central gas supply system.
– The device is connected to the mains power supply.
