General safety instructions
iNOTE
In the event of debility of sight, this user manual can be downloaded at:
www.aat-online.de/gb/um/CR2303
Read the user manual prior to start-up and observe the warning notices and safety instructions.
In the event of reading di󰀩culties, training contents must be broadened verbally.

2 Explanation of the symbols on the package
WARNING
Never touch rotating or moving parts to avoid crushing of ngers and hands!
DANGER
CR23 must not be operated in the case of severe visual impairment and/or blindness!
Do not exceed the approved total weight and the maximum person weight, as this may lead to
defects or overloading of the CR23!
Do not use in rain, wet, snow or ice as the restricted braking capacity may cause slipping!
Do not use on travelators or escalators as doing so may risk physical injury and/or material damage as
a result of crashing or the occupant falling out of the seat.
The operational capability of CR23 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
The stair climbers are guided manually and are operated by an operator.
They make it possible to transport a single person with reduced mobility safely over stairs, upwards
and downwards. The products have been designed for indoor and outdoor use, and moving on spiral
stairs and slopes is possible, too.
4.4 Intended patient population
The intended patient population includes all persons who are able to sit independently and have a
maximum body weight corresponding to the technical specication of the respective model and variant
(max. 230 kg).

12
4.5 Medical requirements and indication
The patients must be able to sit independently. Secure persons, who cannot sit on their own, with belts
(see Accessories). This keeps the occupant from falling out!
The manually guided stair climber assists the accompanying person while transporting the patient over
stairs or slopes, upwards and downwards. The use of the stair climber is intended for patients who
are not able to move by themselves and accompanying persons who do not have su󰀩cient physical
endurance and strength to move the patient over stairs or slopes.
The CR23 is used to transport patients with a weight of more than 140 kg (maximum patient weight:
230 kg).
4.6 Contraindications and restrictions
The stair climbers must not be used if:
- the operator has obtained no training/instruction for the product!
- the operator is below the age of 16!
- there is no supervision for minors of at least 16 years of age!
- the operator is not physically and mentally able to operate the stair climber safely!
- more than one person shall be transported simultaneously!
- the person to be transported cannot sit upright unaided!
- the operator does not have adequate eyesight!
- the braking e󰀨ect is reduced due to rain, wet conditions, snow or black ice!
- the one-side and/or two-side braking e󰀨ect of stair climber 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!
4.7 User group
The stair climbers are intended for the use by:
- medical sta󰀨,
- healthcare professionals,
- driving services, and laymen
Users are trained in the use of the device by means of a training course.

Direct operating force max. 350 N whilst climbing downstairs (chapter 7.6)
Noise level < 70 dB
Storing/operating temperature, device -40° C to +65° C / -25° C to +50° C
Storing/operating temperature, batteries -20° C to +65° C(3) / -25° C to +50° C(3)
Charging temperature, device 0° C to +40° C
Height operating range
(NHN, normal height null) < 3.000 m above sea level
Vibration information The weighted RMS value of acceleration the upper body is exposed to
lies typically below 2.5 m/s².
Type label serial number Left on the power unit and the rear side of the user manual
IP-Protection class PX4 protection class: Protection against splash water from all sides
Classication according to ISO 7176-28:2012 Type C (table 1 of annex A)
1) The climbing speed as well as the range with one charge of the batteries is reduced if the ComfortStep is activated.
2) Never use the stair climber to climb stairs with too little depth because it is no longer possible for the main wheels to touch the steps safely.
3) Temperatures below 0°C will reduce the performance of the battery pack, therefore we recommend a storage temperature of at least 0°C.
