For your safety
2.0 For your safety
• The ATMOS®Chair M 2 has been designed in accordance
with IEC 60601-1/EN 60601. The equipment conforms
to VDE Safety Class I and must only be connected to a
properly installed earthed socket.
• The Chair may be used only under supervision (IEC
60601-1 / EN 60601-1).
• Prior to starting the chair for the rst time, check whether
the supply voltage indicated on the line voltage selector
corresponds to the value of your local mains supply.
• For mains supply, only use the power cable supplied (or an
equivalent one).
• Check proper assignment when assembling country-
specic connections:
- green / yellow: protective conductor
- blue: neutral conductor
- black or brown: phase
• Prior to rst starting up, all connecting leads must be
checked on damage. Defect cables must be replaced.
• To disconnect the chair from the mains supply, rst
remove the plug from the safety connection socket. Then
disconnect the connection line from the chair. Never touch
plug or line with wet hands.
• Please observe the ambient conditions stated in the
technical data (chapter 8.0).
• The ATMOS®Chair M 2 is not designed for use in
explosion-hazardous areas. Explosion-hazardous areas
may be caused by the use of ammable anaesthetics, skin
cleansing products and skin disinfectants.
• Ensure that your patient sits in the middle of the seat.
A constant unilateral strain on the seat can damage the
surface.
• The user must be familiar with the operation of the chair.
• ATMOS is not liable for personal injury and damage to
property if
- no original ATMOS parts are being used,
- the advice for use in these operating instructions is not
being observed.
• Please note:
A medical insulating transformer with earth leakage
monitor or any similar safety system acc. to EN 60 601-1
is required, if several devices are connected over one
common power supply. The transformer must correspond
to the power consumption of all the devices to be
connected.
• The electric motor is protected by an integrated thermo
protection switch. After 1.5 minutes of continued operation,
the motor needs a cool down period of approx. 8.5
minutes. If the thermo protection switch activates, the
motor needs a cool down period of approx. 20 minutes.

3.0 Setting up and starting up
3.1 Assembly
• Always place the device on level, solid surface.
3.2 Starting up
• Set up product at the desired spot. Any oor unevenness
must be compensated for.
• Check that the upper part of the chair can rotate freely.
• Peruse safety information in part 2.0 prior to starting up
the device for the rst time.
• Finally, connect power cable.

3.3 Electrical connection
The ATMOS®Chair M 2 is supplied with a power cable and
IEC connection. Insert the power cord to the IEC socket at
the back side of the chair base and the wall mounted power
outlet.
Make sure, power outlet features a proper ground connection.
Find all relevant electrical data (voltage and nominal
frequency) as well as the data for fuses on the label located
between the sockets.
To disconnect the device, pull the mains plug out of outlet
socket.
)There is no indication that the product is hooked up to line
power.
)Disconnect chair, if not in use, during service and repair
work and or for cleaning.

4.3 Rotating the upper part
The upper part of the chair with the patient can be completely
rotated after having loosened the brake with the locking lever
(, g. 3).
The upper part with the patient can then be rotated in the
desired direction.
If the brake is only slightly xed the chair can be rotated
without loosening the brake.
4.4 Adjusting the backrest
• Press lever element (, g. 3) downwards.
• Adjust backrest to the desired position.
• Release lever element which will then return to its initial
position,
• Backrest is arrested.
4.2 Adjusting the seat height
The height adjustment of seat cushion level is controlled by 2
foot switches (g.2):
= Up
= Down
Furthermore, the ATMOS®Chair M 2 features an “Auto –
Down (homing)” function, to lower the upper part of the chair
down to its lowest level after a short tap on the foot switch.
Pressing the right foot switch for less than 0.5 seconds will
move the chair to home position. To stop the movement, just
briey tap the switch again.
4.0 Operation
4.1 Positioning the patient
Ensure that your patient sits in the middle of the seat.
A constant unilateral strain on the seat can damage the
surface.

4.5 Adjusting the headrest
• Loosen the arresting button on the rear of the backrest by
turning it anti-clockwise,
• Adjust the headrest to the desired height (it may not be
extended by more than 10 cm),
• Arrest the headrest by turning the arresting button
clockwise.
4.6 Removing the headrest
• After having loosened the arresting button, the headrest
can be removed upwards from its support.
4.7 Removing the foot support
• Loosen the arresting screws (bottom of the seat).
• Remove the foot support forward.

5.1 General information on cleaning and disinfection
5.0 Cleaning and care
Prior to cleaning
Medical chairs like the ATMOS®Chair M 2 must be fail safe at all times.
We therefore recommend:
prior to each use:
if
necessary
5.2 Cleaning the device surface and upholstery
If liquid has penetrated the device, it may not be operated again until it has been checked by the authorised customer service
centre.
• The surfaces of the ATMOS®Chair M 2 are resistant against all the recommended surface disinfectants stated in chapter
5.3 and 5.4. Nevertheless after any length of time discolourations could possibly develop. Polar solvents (e.g. acetone or
chlorinated hydrocarbons (CCs)) may not be used for cleaning and disinfecting.
• Disconnect the power plug from the power supply prior to cleaning and disinfecting the device surface.
• The device itself can be wiped off with a moist (not wet) cloth.
Do not use aggressive or abrasive cleansing agents. For the upholstery usual dry foam may be used.
Treatment with a commonly used care product for articial leather is recommended once a week in order to keep the upholstery
soft and smooth.
!
)The described action relating to cleaning and disinfection
resp. sterilisation do not substitute the relevant instructions
which must be adhered to prior to operation!
• For disinfection, you may use all surface and upholstery
disinfectants listed in chapter 5.3 and 5.4 “Recommended
disinfectants”.
)Always observe the concentration specications and
instructions by the respective manufacturer!
• Do not use
- Disinfectants which contain organic or inorganic acids
or bases as they could cause corrosion damage.
- Disinfectants containing chloramides, phenol derivatives
or anionic tensides, as these may cause stress cracks
in the material used for the housing of the unit.

equipment and the ATMOS®Chair M 2
NOTE 1
With 80 MHz and 800 MHz the higher frequency range applies.
NOTE 2
These guidelines may not be applicable in all cases. The emanation of electromagnetic waves is affected by absorption and
reection of buildings, objects and people.
a
The eld strength of stationary transmitters, such as base stations of cellular phones and mobile terrain radio equipment,
amateur radio transmitters, cbm broadcast and TV stations cannot be predestined exactly. To determine the electromagnetic
environment in regard to stationary transmitters, a study of the location is to be considered. If the eld strength measured at
the site where the ATMOS®Chair M 2 is used exceeds the compliance level above, the ATMOS®Chair M 2 must be observed
to demonstrate proper function. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the ATMOS®Chair M 2.
b
Within the frequency range of 150 kHz to 80 MHz the eld strength should be below 3 V/m.
The ATMOS®Chair M 2 is intended for use in an electromagnetic environment in which HF disturbances are controlled. The
customer or user of the ATMOS®Chair M 2 can thereby help to prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile HF communication equipment (transmitters) and the ATMOS®Chair M 2 - depending on
the output of the communication device as indicated below.
