void!
We reserve the right to perform structural modications to the treatment chair for the purpose of adapting the
product to the currently valid state of the art and for the purpose of improving the product.
2.1. Basic safety instructions
The equipment described in this user manual has been designed and tested in compliance with the relevant
safety standards and the national and international rules and regulations. This regulation compliance guarantees
a superior level of equipment safety.
Our goal is to provide you with comprehensive information on all safety aspects pertaining to the handling of this

• Keep moisture away from live components. Moisture may cause short-circuits.
• Never use damaged cables or plugs or loose wall outlets.
• Do not put the chair into or out of operation by plugging or unplugging the mains connection cable.
• Never touch cables with moist hands and do not pull on them.
• Cables must never be bent or otherwise damaged.
• Electrical components like the manual keypad or foot keypad should be pre-cleaned with a dry cloth and

Warning
Prevention of electromagnetic interferences in environments characterized by the controlling of radiated
high-frequency disturbances.
During emergency situations requiring the use of a debrillator it is important to refrain from operating the treatment
chair’s electrically powered adjusting functions. The chair‘s running motors may interfere with the debrillator’s
normal operation. Electromagnetic interferences between the devices cannot be ruled out entirely.
• Switch o the treatment chair and disconnect it from the power supply so that all current ow to the electrical
adjustment functions is safely interrupted.
The same applies to the use of high-frequency surgery equipment! Electromagnetic interferences between these
devices and the treatment chair cannot be ruled out entirely.
• Activating the electrical adjusting functions for positioning the patient during this type of intervention/
treatment is therefore strictly prohibited!
Caution
• Unauthorized structural alterations by the operators or operating sta are prohibited!
• Strict adherence to the load limits specied in Section „9. Technical Specications“ is mandatory.
• When selecting a location for the treatment chair, please pay attention to adequate space for patient
movement while entering or exiting the chair.

2.2. Personnel Qualication
The treatment chair may only be assembled, operated, maintained and repaired by persons who have received the
required training or possess the appropriate knowledge and experience. Any works to the equipment’s electrical
components may be performed only by a skilled and qualied electrician.
2.3. Intended Use
The term “intended use“ denotes the treatment chair’s operation including any routine checks thereof in
accordance with this instruction and service manual.
The treatment chair is intended for sole use either by the caregiver/surgeon as an electrically adjustable treatment
chair designed for the proper positioning and support of the patient for diagnostic and therapeutic purposes of
temporary (< 60 min) to short duration (usually less than 5-8 hours) or by instructed, qualied medical personnel.
The treatment chair and its functions have been designed to address the needs of out-patient medical diagnostic
and treatment methods.
The quick adjustability of the chair, with 8-fold auto-run function and the easy access of the surgeon to the
treatment eld „head/face“ allow an ergonomic working method, especially optimized for ambulant operation
techniques with high patient turnover:
• IVOM treatments / ophthalmology
• aesthetic treatments
• dermatological applications
• dental examinations
The treatment chair has been designed to accommodate the accessories commonly used in this medical
environment (e.g. paper roll, hand remote bracket).
The equipment with 2 integrated, lowerable xed castors and an additional 3rd swivel castor make it possible to
manoeuvre and push the treatment chair if a change of location is necessary.
The intended use of the treatment chair is carried out via an integrated power supply unit including isolating
transformer with protective low voltage. The treatment chair technical safety equipment and ease of disinfection
make it perfect for use in cleanroom class 0, 1 and 2 medical-use rooms. It is not permitted to activate the chair’s
adjusting functions during the course of medical treatments and/or surgery. Medical surgery may only be
performed when the device is switched o.
Be sure to use the treatment chair only on perfectly horizontal ground (10-degree slope max.).
The loads applied to the treatment chair should not exceed 240 kilograms max.
The manufacturer will not be held liable for damages resulting from unintended use not in compliance with the
denition set forth herein.
