2 Product description
2.1 Function
The wheelchair is designed solely for individual use by persons who are unable to walk or who have a walking
impediment, and can be operated either by the patient or by an attendant.
The wheelchair can be used on solid ground both indoors and outdoors.
The power wheelchair is equipped with rear-wheel drive for good directional stability and to enable a small turning
radius.
The drive system with two 12 V batteries combined with spring-mounted drive wheels allows obstacles to be
crossed easily (Category B according to EN 12184) and offers safe operating performance.
The power wheelchair is equipped with front-wheel drive for excellent directional stability.
The drive system with two 12 V batteries combined with spring-mounted drive wheels allows obstacles to be
crossed easily (Category B according to EN 12184) and offers safe operating performance.
The power wheelchair is equipped with mid-wheel drive for good directional stability and to enable a very small
turning radius.
The drive system with two 12 V batteries combined with spring-mounted drive wheels allows obstacles to be
crossed easily (Category B according to EN 12184) and offers safe operating performance.
The power wheelchair is controlled by the VR2 wheelchair control device (see Page25). The latter includes a con
trol panel to enter driving commands and display the current status as well as a controller that operates the drive
motors and other electrical functions based on the inputs.
The power wheelchair is controlled by the R-Net wheelchair control device (see Page25). The corresponding
TEN° control panel serves to enter driving commands and display the current status. The control electronics in the
controller make it possible to control the drive motors and other power functions based on the input data.
The special features of the power wheelchair include:
• Individual adaptation possibilities for control device using programming and options.
• Individual adaptation possibilities with options and custom fabrication using modular components (chassis,
seating system, control device, accessories).
• Modular design that allows the power wheelchair to be equipped with additional modules and installed equip
ment in addition to the main components, suchas power seat adjustments, special controls, tray.
• Serviceability due to easy, straightforward access to all components.

►Please note that certain options and add-on components will reduce the remaining load capacity.
WARNING
Exceeding the service life
Serious injuries due to failure to observe the manufacturer's requirements
►Using the product beyond the specified expected service life (see Page111) leads to increased residual risk
and should only take place subject to the due diligence and deliberations of qualified personnel.
►If the service life is reached, the user or a responsible attendant should contact the qualified personnel who
fitted the product or the manufacturer's servicing department (see inside rear cover or back page for

3.3 Effects of electromagnetic interference on the product and on the user
CAUTION
Use of mobile devices with electromagnetic emissions (e.g., mobile phones)
Falling, collision with persons or objects due to interference with the control signals
►Turn all mobile devices off while driving, since the driving characteristics of the product are affected by elec
tromagnetic fields.
►Turn the control unit off when it is not required, since the product may generate electromagnetic fields that
can cause interference with other devices. The product has been tested according to EMC regulations.
►Notwithstanding compliance with all applicable EMC directives and standards, the product can be affected by
interference from other electric devices (e.g., department store EAS systems) or cause interference with such
devices. If this occurs, move your product outside the interference range.
• Powered wheelchairs may be susceptible to electromagnetic interference (EMI), which is interfering electro
magnetic energy (EM) emitted from sources such as radio stations, TV stations, amateur radio (HAM) transmit
ters, two-way radios, and cellular phones.
• The interference (from radio wave sources) can cause the powered wheelchair to release its brakes, move by
itself, or move in unintended directions.
• It can also permanently damage the powered wheelchairs control system.
• Because EM energy rapidly becomes more intense as one move closer to the transmitting antenna (source),
the EM fields from hand-held radio wave sources (transceivers) are of special concern. It is possible to uninten
tionally bring high levels of EM energy very close to the powered wheelchair's control system while using these
devices. This can affect powered wheelchair movement and braking.
• Other types of hand-held devices, such as cordless phones, laptop computers, AM/FM radios, TV sets, CD
players, and cassette players, and small appliances, such as electric shavers and hair dryers, so far as we
know, are not likely to cause EMI problems to your powered wheelchair.

The maximum load capacity (see print on the nameplate; see Page15) is thereby respectively reduced by the
weight of the retrofitted options.
4.2.1 Accessories from other manufacturers
As per the order for the power wheelchair, some components from third-party manufacturers have been installed
prior to delivery. Please observe the following instructions in this regard:
• Accessories from other manufacturers must be intended for use on wheelchairs and must fulfil all currently
applicable legal requirements under the Medical Devices Act as well as further applicable standards.
• When using the accessories from other manufacturers, the instructions for use / manufacturer's instructions for
the relevant accessories must be strictly observed. These are included with the instructions for use.
• Ottobock assumes no liability for combinations with medical devices and/or accessories from other manufac
turers not included in Ottobock's modular system.
• In case of questions or problems with accessories from other manufacturers, please contact the qualified per
sonnel who adjusted this product.
4.3 Storage
4.3.1 Storage during daily use
The power wheelchair should always be protected against external influences.
The control unit must be turned off.
4.3.2 Storage during extended disuse
NOTICE
Deep discharge
Battery damage due to standby current
►Deactivate the circuit breaker if the wheelchair is not used for more than 3 days.
►To deactivate the circuit breaker: see Page19
Please observe the following if the power wheelchair is not used for more than 3days:
Storage conditions
• Maintain an ambient temperature between -15°C and +40°C (5°F and +104°F) and relative humidity
between 45% and 85%.
• Store the power wheelchair in a dry, enclosed room with sufficient air circulation and protection from external
influences.
• Protect the wheels against ground frost, e.g.by relieving them completely through assembly blocks or wooden
boards.
• Maintain sufficient clearance from sources of heat. If the product is parked for an extended period of time or
the tyres overheat (e.g.in the vicinity of radiators or in case of exposure to strong sunlight behind glass), the
tyres may become permanently deformed.
• Fill pneumatic tyres with slight overpressure.
• Rotate the wheels weekly to prevent flat tyres from extended standing.
• For extended storage, store the power wheelchair so the wheels are not in contact with the ground.
Note regarding the tyres
• If the power wheelchair is not moved for several days, permanent colour changes may occur where the wheel
chair comes into contact with the surface it is standing on. Therefore a suitable mat should be used when park
ing it for extended periods of time.
• Tyres contain chemical substances that can react with other chemical substances (such as cleaning agents,
acids, etc.).
• Black tyres contain soot particles. They may leave black marks where they come into contact with the ground.
Therefore the manufacturer recommends grey tyres if the wheelchair is primarily used indoors.
• Avoid unnecessary parking outdoors. Direct exposure to sunlight/UV radiation causes the tyres to age more
quickly. As a result, the tread surface hardens and corner pieces break out of the tread.
• The tyres must be changed when the tread is less than 1mm (0.04") to ensure safe driving behaviour.
• The tyres should be replaced every 2years regardless of wear and tear.
• When power wheelchairs with PU tyres are parked for long periods, the tyres may become deformed (flat
spots). This deformation will go away on its own over time while driving.
