26 How the device works
DC vehicle cable
For mobile use of the point 2, e.g., in a truck or a car-
avan, it is possible to operate it with a 24 V direct cur-
rent (DC). For this you will need the optionally available
DC vehicle cable.
Only use the optional DC vehicle cable to connect
the device to a DC power supply.
Battery pack
To use point 2 while travelling and when mains cur-
rent fails, the device can be operated with the
optionally available powerpackpoint 2 battery pack.
With the battery pack, point 2 CPAP and point 2
Auto CPAP can be used at least 8 hours (at 10 hPa,
12 bpm, 500 ml tidal volume). With the point 2 BILEVEL
ST20 an operating time at least 7 hours is possible (at
IPAP = 12 hPa, EPAP = 6 hPa, 12 bpm, 300 ml tidal vol-
ume, I:E = 40% : 60%, T mode).
Before using the battery pack, ensure that you
have read the powerpackpoint 2 user‘s manual.
