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.

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

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.).
