POWER SUPPLY
The ventilator can be supplied with power from 3 different sources:
• Power supply from power socket
• Internal battery
• External battery pack (optional accessory)
The ventilator automatically detects which power sources are available. If
the device is connected to an external voltage source via the power sup-
ply unit, this is always used fi rst, and then the internal battery. The current
power source is indicated by the corresponding LED.
MAINS OPERATION
Only the power supply cable supplied may be used for operating the
device from the mains.
1. Insert the power plug into the mains socket on the rear of the device.
2. Connect the mains cable to the power supply.
3. Plug the mains cable into a power socket.
4. The power LED lights up green and the battery LED shows the cur-
rent charge status.
5. Switch the ventilator on using the main switch.
As soon as the ventilator is connected to a power supply of 100 - 240 V
(-20 %, +10 %), 50/60 Hz, the power LED lights up green.
The power LED is also lit when the main switch is off, as the internal bat-
tery is charged. The charging of the battery is additionally indicated by

symbol is shown on the display.
