3Safety Information
3.1 General information
The Rotary Chair is constructed to a maximum patient weight of 135 kilos
This instruction manual is a part of the instrument and should always be kept at hand.
It documents the state of development of the unit, valid at the time of printing, and contains all the
information required by the IEC 60601-1.
Exact adherence to the instruction manual is a prerequisite for the perfect and intended functioning of
the Interacoustics instrument.
Always be sure to disconnect the power supply before cleaning or disinfecting mains operated
instruments.
Interacoustics A/S only guarantees for the safety, reliability and function of the instrument, if:
installation, extensions, modifications and repair are exclusively carried out by personnel authorized by
Interacoustics A/S;
the room in which the equipment is installed complies with the country-specific regulation;
the installation site complies with the ambient conditions of the instrument;
the unit is used in accordance with the instruction manual after initiation in the operation;
The device is not conceived for operation in potentially
explosive rooms or flammable atmospheres.
If fluid gets into the instrument, the instrument will have to be switched off at once. The fluid must
immediately be removed by Interacoustics service technicians and the instrument tested for technical
safety. Defective connectors and leads must immediately be replaced or repaired by a specialist or by
personnel authorized by Interacoustics A/S.
3.2 Electrical safety
Protection Categories:
For the protection of patients and the operating staff, special, country-specific regulations for medically
used rooms and electro-medical equipment have been issued.
According to these regulations, mains operated equipment must have reliably isolated live parts as well
as an additional protection to prevent mains voltage from being passed onto unprotected parts.
The IEC 60601-1 has classified various protection categories.
Protection Category I, a protective measure with ground conductor, is primarily applied to electro-
medical equipment.
Protection Category I includes equipment whose metal case may be live in the case of an error and
which is connected to the ground conductor of the mains network via the ground contact. A circuit
breaker will be trigged if the insulation fails.

Rotary Chair Nydiag 200 Page 5
Interacoustics equipment is in compliance with Protection Category I
Connection of equipment of type BF inside or outside medically utilized locations
Due to the increased safety requirements, medically applied instruments must not be connected via an
extension flex or a multiple socket outlet.
The instrument must exclusively be connected via a wall
socket with a ground contact!
Never connect the instrument to a power outlet before all
panels and fittings have been securely mounted
Coupling of equipment to other systems
External equipment intended for connection to signal input, signal output or other connector, shall
comply with relevant IEC standard (e.g. IEC 60950 for IT equipment and the IEC 60601 series for
medical electrical equipment). In addition, all such combinations - systems - shall comply with the
standard 60601-1-1, Safety requirements for medical electrical systems. Equipment not complying with
IEC 60601 shall be kept outside patient environment, as defined in standard (at least 1.5 m from the
patient).
Any person who connects external equipment to signal input, signal output or other connectors has
formed a system and is therefore responsible for the system to comply with the requirements of IEC
60601-1-1. If in doubt, contact your service technician or local representative for help
Should any further information be required, please do not hesitate to contact your Interacoustics
representative.
3.3 Ambient conditions
Interacoustics equipment has not been conceived for operation in medically utilized rooms with
potential explosion hazards.
The equipment should not be installed in the vicinity of e.g. X-ray equipment, motors or transformers
with high installed power rating, since electric or magnetic interferences may falsify the results of a
measurement or even make measurements impossible.
Therefore, the instrument should not be installed in the vicinity of power lines.
If not otherwise stated in the shipping documents, Interacoustics equipment in the normal encased
version has been conceived for operation under normal climatic ambient conditions.
Temperature:
+ 15°C/+59°F
…
+ 35° C/+95°F
Relative humidity:
30
…
90 %
Barometric pressure:
500
…
1060HPA

Rotary Chair Nydiag 200 Page 6
Thus, the units should be effectively protected against moisture. Ventilations lots should be kept
unobstructed for maintaining circulation of air.
The instruments should generally be stored at temperatures between 0° to +50°C/+32° to 122°F.
3.4 Hygiene
Always be sure to pull the plug before cleaning or disinfecting mains operated instruments.
The instrument must be cleaned with a non-fuzzy, slightly
moistened piece of cloth (please do not soak it!) Only use a mild
alcoholic fluid as a disinfectant.
When cleaning the instrument, any moisture, like e.g. condensation water, must necessarily be
prevented from getting inside!
Chemicals required for operation or care of the unit must always be stored, prepared and made
available in specially labelled containers to prevent any mistakes.
3.5 Maintenance
Before switching on the instrument make sure that the mains cable, mains plug, socket and input at
the instrument are in a perfect state. If the drive of the rotary chair becomes noisy the driving belts
should be renewed. We recommend renewing the driving belts after five years.
The operator is responsible for the perfect state of the instrument. It is recommended by
Interacoustics to have safety checks carried out at one-year intervals.
Immediate maintenance is required if:
the instrument was subjected to extreme mechanical stress (impact, defective cable due to
inadmissible traction);
fluid gets into the instrument;
cables and/or connectors are defective;
rubber-joints have developed cracks.
For further details please contact your Interacoustics representative.

4Installation
Never pull the backrest or the armrests to move the chair.
Before attempting to move the chair, the four side panels must be unscrewed to provide access to the
frame. With the panels removed, the chair can be lifted and moved by the frame.

Rotary Chair Nydiag 200 Page 8
1. To get access to the frame, first loosen the resin cover. This is done by unscrewing the 4
hexagon screws holding the upper steel ring (use a 3.0 mm hexagon key):
2. Unscrew the curved side panels. Each panel is fixed with 4 screws. Use a 3.0 mm hexagon key
to loosen the screws:

Rotary Chair Nydiag 200 Page 9
After removing all four curved panels, the bared frame can easily be gripped to lift and move the chair.
Once the instrument has been positioned in its final location, re-mount the side panels and the
top cover, and secure with correct type of hexagon screws.

5Putting the Unit into Operation
5.1 Examination Room Layout
The Rotary Chair may be installed using the following guidelines for room size and hardware
installation:

Rotary Chair Nydiag 200 Page 11
5.2 Hardware installation
The rotary chair must be secured to the floor with 4 screws
through the bottom rim of the base. Please use 14 mm dowels
and 10 mm screws.
When orienting the chair in the examination room please observe that the default zero position of the
chair is indicated by the exit point of the cables from the chair.
Never connect the instrument to the power outlet before the side
panels and the top cover have been correctly refitted and
secured.
Consult with the product specification plate on the unit for compliance between the unit‟s own data and
those of the local power supply system (mains voltage and mains frequency) before connecting the
unit.
Connect only if all data agrees!
Inspect the mains connection cables for visible damage prior to establishing the connection. Damaged
cables or plugs must immediately be replaced by Interacoustics service technicians, an authorized
person or specialist.
Connection Panel
The backrest features a connection panel with purpose specific connections:
2 x 6-pM FireWire ports
1 x USB 2.0 port
1 x DC out (not active)
