There are labels on the wheels and the battery charger which con-
tain various details on the product. In the event of a system defect,
components can be replaced by your specialist dealer aspartofthe
Alberexchangepartspool. Your specialist dealer will need some of
the information given on the labels.
System label on the twion wheel
Please specify the system number of the wheel when exchanginga
device as part of the Alber exchange parts pool.
The system label is on the back of the twion wheel.
“Safety inspection” label on the twion wheel
The label should remind you when your next safety inspection is
due.
It is on the back of the twion wheel.
“Technical data” label on the battery charger
The label shown in the adjacent diagram is found on the underside
of the battery charger and provides information on its technical
data.
Component label on the battery charger
Please specify the component number of the battery charger (num-
ber in the middle of the label, shown by an arrow in the adjacent
diagram) when replacing the device withintheAlberexchange
parts pool.
The component label is on the underside of the battery charger.

The quality of the supply voltage
should be up to that of a typical
business or hospital environment. If
the user of thedevice or system
requires continued function during
interruptions of thepower supply it is
recommended to supply thedevice or
system from anuninterruptible power
supply or a battery.
Magnetic field at the mains
frequency (50/60 Hz)
as per IEC 61000-4-8
3A/m3A/mMagnetic fields at the mains frequency
should conform to typical values, as
found in business and hospital
environments.
NOTE: UTis the AC supply voltage before application of the test level.
Recommended safety distances between portable and mobile
HF telecommunications devices and the non life-sustaining device or system
The systems discussed in this manual are intended for use in the type of electromagnetic environment specified
below that have controlled RF interference levels. The customer or user of the device or system can help avoiding
electromagnetic disturbances by observing the minimum distance -which depends on the power output of the
communication device, as given below -between mobile RF communication devices (senders) and the device or
system.

For transmitters which have a maximum rated power which is not indicated in the above table, the recommended safety distance d in metres(m) can be
determined using the equation belonging to the respective column, whereby P is the maximum rated power of the transmitter in Watts (W) according to the
transmitter manufacturer's specifications.
NOTE 1:
The higher frequency range applies at 80 MHz and 800 MHz.
NOTE 2:
These guidelines may not necessarily be applicable in all cases. The propagation of electromagnetic variables is influenced by absorption and reflection
valuesassociated with the buildings, objects and people around.
