Introduction1
The aks‑S4 homecare bed meets the requirements of a modern homecare bed and can ideally be
integrated into the existing residential environment due to its wood decor. It has been tested for the
application cases 3 and 4 of the standard EN 60601‑2‑52. This includes use in domestic care and in
old people’s and care homes. The use of the aks‑S4 homecare bed means more quality of life for the
patient and making the work easier for the care personnel.
Among other things, the aks‑S4 homecare bed is also distinguished by the following features:
safety due to modern switch mode power supply (SMPS) with surge voltage protection, short•
circuit protection, overcurrent and temperature shutdown
minimal electromagnetic waves; as a result, no transformer humming is possible•
electricity saving because the power supply is in standby mode when the bed is not being•
operated
safety due to 29 V instead of 230 V from mains adapter, i.e. no 230 volts voltage in the power•
lead and at the homecare bed
motorised height and back part adjustment•
patented possible adjustment of thigh and lower leg part using the manual control unit by•
the patient without manual lifting of the lower leg part
homelike ambience due to wood decor•
integrated wood side grills•
individually lockable castors•
uplifter•
suitable for installation alone•
The present operating manual gives you the necessary information for safe use.
Read and observe this operating manual before every use.
In the case of a change of owner, pass on this operating manual.

Intended purpose2
The aks‑S4 homecare bed is an active Class I medical product according to EU Council Directive
93/42/EC, Appendix IX.
The intended use of the aks‑S4 homecare bed is sleeping / resting. It is used for alleviation of or
compensation for an injury, disability or illness and for making the working conditions easier for the
carers.
It has been tested for the application cases 3 and 4 of the standard EN 60601‑2‑52. It is therefore
intended both for domestic care as well as for long‑term care in a medical sector (e.g. old people’s
homes and care homes, rehabilitation facilities, geriatric facilities).
The bed is suitable for adult patients and not for children. The suitability of the homecare bed for the
patient must be determined by the professional assessment of the health professional.
The homecare bed is only suitable for dry indoor areas.
The climatic conditions must be an ambient temperature of 0 °C to 40 °C, humidity of 20% to 80%,
air pressure of 700 hPa to 1060 hPa and in the range of normally composed atmospheric air. The
homecare bed is not EX‑protected and must not be operated in potentially explosive areas.
The homecare bed does not have any potential equalisation and is thus not suitable for medical,
electrical applications.

General safety instructions3
Only use the homecare bed in accordance with its intended purpose, the requirements of•
the medical products law and all related legal regulations, the occupational health and safety
and accident prevention regulations as well as the generally recognised rules of standard
engineering practice.
Note that this homecare bed is a medical product and the Medical Products Operator•
Regulations (MPBetreibV) are binding for the operating organisation / user.
The requirements for the electrical installation of the room / area where the homecare bed is•
connected and operated must comply with the state of the art.
Only use the homecare bed if you have been instructed about its handling and you have the•
corresponding expert knowledge.
Read the operating manual completely before commissioning in order to avoid damage due•
to incorrect operation or hazards. It contains important information and instructions which
are necessary for the proper operation of the homecare bed.
Only use the homecare bed in accordance with the present operating manual. Keep the•
operating manual safely for possible reference. Include this operating manual in the case of
change of ownership of the homecare bed.
Ensure the homecare bed and its accessories are in proper, fault‑free condition before every•
use.
Note that the installation, operation, maintenance and repair of the homecare bed must only•
be performed by suitable qualied personnel.
You as the user and/or owner must ensure (e.g. by corresponding instructions and•
precautions) that mechanical load of the 29 V power cable during use is avoided (e.g. kinking,
shearing, driving over the cables with the homecare bed itself or with equipment trolleys,
loads during room cleaning etc.). This also applies to cables for other equipment which is
used in combination with the homecare bed.
Pay attention to compliance with the activation time and the safe working load. These must•
not be exceeded, otherwise reliable operation can no longer be guaranteed (see Chapter
7 Commissioning and Chapter 21 Technical Data).
Protect the aks homecare bed from direct sunlight and heat.•
Ensure that no moisture penetrates into the electrical system.•
Note that possible electromagnetic or other inuences between the homecare bed and other•
equipment cannot be ruled out. If there is a risk of interactions, disconnect the homecare bed
from the mains power supply by unplugging the mains adapter.

aks-S4
Page 6
z4200064_GA_Bett_S4_151015_EN
Faults due to the use of mobile communications devices cannot be completely ruled out.•
Therefore, maintain a safety distance of at least 3.3 m to guarantee reliable operation of the
homecare bed. ‑ See position paper of the German Federal Institute for Drugs and Medical
Products (BfArM) (reference No.: 9 / 0508) ‑
Do not leave children in the surroundings of the homecare bed unsupervised. If necessary,•
remove the mains adapter from the mains power socket and block the manual control unit
against unauthorised operation.
If you leave the person to be cared for unsupervised, move the lying area to the lowest•
position in order to reduce the risk of injury due to falling when getting in and out of the bed
or by falling out.
If the homecare bed has to be moved, lower the lying area elements so that they are horizontal•
and put the bed in the lowest position. Raise the side grills for the patient transport. Attached
equipment must be removed.
Use the side grills if there is a danger of the person to be cared for falling out of the bed.•
Note that the side grill only provides protection against falling out if it is raised on both sides
(head and foot) and if the lying area elements such as back, thigh and lower leg part are in the
horizontal position.
Only use original side grills as these have been approved by aks and ensure faultless and safe•
function.
‑‑ Non-original aks side grills can cause hazards! ‑‑
When using the side grills, check their suitability for the respective bed user taking account•
of his special characteristics. Pay particular attention to the distances between the bars and
stays in relation to the physique of the bed user. Check whether the side grill height from
the top side of the mattress is at least 220 mm. If this is less than 220 mm, use our tested and
approved side grill height extenders.
There is a higher risk for unsupervised persons lying in the bed who are also mentally•
deranged or extremely fragile. Strictly comply with the safety instructions shown here in order
to minimise the residual risk. Block the manual control unit if necessary.
In the case of unusual noises, damage or malfunction, the homecare bed must not be further•
operated. Disconnect the homecare bed from the mains power supply by unplugging the
mains adapter from the mains power socket. Inform your authorised dealer.
