Information about the device types:
This user manual has been universally created for the device types SOLO and SOLO+. These travel
drives di󰀨 er only in the technical data and in the colouring. You can tell which type of device you have
by the serial number (chapter "Type plate incl. serial number"). All chapters listed apply to both device
types. Please note whether a lithium-ion battery pack (ALPHA BOX / integrated battery indicator) or a
lead gel battery pack (BETA BOX / without battery indicator) is present.
The SOLO has been successfully tested by TÜV Süd Product Service GmbH in Hanover according to
DIN EN 12182, DIN EN 12184 and the relevant parts of ISO 7176-14.
People with visual and reading impairments or intellectual disabilities should print out the user
manual available on the website in enlarged letters or have this manual read to them, if necessary.
On our homepage, you will also  nd all safety-related changes which have been made to the
user manual. All versions with details of the production period of the product are obtainable at:
www.aat-online.de/de/bda/SOLO
All serious incidents occurring in relation to the device must be reported to the manufacturer and to the
competent authority of the Member State where the user and/or occupant is established.
WARNING
Failure to observe this user manual, in particular the safety instructions, can lead to defects in the SOLO
and endanger the user and persons in the immediate vicinity of the SOLO. There is an increased risk of
injury! In the event of an infringement, claims for warranty and liability are excluded!
The product is state of the art and complies with the associated technical safety requirements.
Nevertheless, a low level of residual risks cannot be ruled out. Please observe the safety instructions
to this end.

occupant and the occurrence of damage to property!
The operational capability of the SOLO can be inuenced by electromagnetic elds (e.g. by mobile
phones, electric generators or high-voltage sources)!
Do not store near medical devices, for example with a life support function,
and diagnostic devices, as these may malfunction!

4.3 Intended purpose
A travel drive is an electrical transport device and is attached to a manual wheelchair. The objective of
the electrical transport device is to make movement with a manual wheelchair easier for a self-propelled
person and to increase or fully take over the force generation for the movement of the wheelchair. This
shall maintain autonomous movement and increase mobility and exibility for the patient.
The travel drive can be used indoors and outdoors on level surfaces and upward and downward slopes.
The devices are controlled by the patients themselves or by an operator.
4.4 Intended patient population
The intended patient population includes all persons who are able to sit independently.
Users of the SOLO may have a maximum passenger weight of 165 kg (lithium-ion battery) or 160 kg
(lead gel battery). Users of the SOLO+ may have a maximum passenger weight of 205 kg.

12
4.5 Medical requirements and indication
4.6 Contraindications and restrictions
The operator must be physically and mentally able to operate the product.
The SOLO / SOLO+ transport device replaces the physical generation of force by the patient on a man-
ual wheelchair. The use of the transport device is intended for patients who own a manual wheelchair
but do no longer have su󰀩cient physical endurance and strength to move by themselves.
The optional control unit is used when the wheelchair user does no longer have the motor ability to move
the wheelchair by himself/herself by operating the joystick control, and the strength of the accompanying
person is not enough to steer and/or push and brake a person sitting in the wheelchair.
The travel drives must not be used if:
• the operator has obtained no training/instruction for the product!
• the operator is not physically and mentally able to operate the travel drive safely!
• more than one person shall be transported simultaneously!
• the operator does not have adequate eyesight!
• the braking e󰀨ect is lost due to rain, wet conditions, snow or black ice!
• the braking e󰀨ect of the travel drive does not set in!
• escalators or travelators shall be overcome!
• medical devices with e.g. a life support function, and diagnostic devices are in the proximity!
• it is not used according to the intended use!
• objects shall be transported!
4.7 User group
The travel drives are intended for their use by patients and lay operators.
Users are trained in the use of the device by means of a training course.
