– UL – CSA In accordance with Directive 93/42/EEC, the complete quality manage- ment system of the company Carl Zeiss has been certified by the DQS Deutsche Gesellschaft zur Zertifizierung von Managementsystemen mbH, a notified body, under registration number 250758 MR2.
Use this instrument only for the applications described. • Only use the instrument with the accessories supplied. Should you wish to use other accessory equipment, make sure that Carl Zeiss or the equipment manufacturer has certified that its use will not impair the safety of instrument.

Safety • Only personnel who have undergone training and instruction are al- lowed to use this instrument. It is the responsibility of the customer or institution operating the equipment to train and instruct all staff using the equipment. • Keep the user's manuals where they are easily accessible at all times for the persons operating the instrument.
Page 13
Safety • Pay special attention to warning symbols on the instrument (triangular warning signs with exclamation marks), labels and any parts such as screws or surfaces painted red. For every use of the instrument • Avoid looking directly into the light source, e.g. into the microscope ob- jective lens or a light guide.
Safety When using a fundus imaging system (e.g. BIOM II) When using a fundus imaging system (e.g. BIOM II from the company Oc- ulus) which is usually installed between the surgical microscope and the patient, make sure that the patient is neither put at risk nor injured by the motorized focusing system or the movement of the stand arm.

Safety In the following, comments on these aspects are given and a description of how Carl Zeiss, as a manufacturer, makes allowance for them in its in- struments. Illumination characteristics (spectral composition) Studies on exposure of the eye to light of varying spectral composition date back to the early 1950s.
Page 16
Also, the surrounding light sources should not cause addi- tional strain to the patient's eye. Carl Zeiss has provided an answer to this problem in the form of a swing- in retinal protection device for insertion into the beam path of the surgical microscope.
Page 17
Such factors would be expected to significantly extend the time at which photoretinitis might occur. In conclusion Carl Zeiss recommends: – Use of the GG 475 eye protection filter. – Reduction of the illumination of the surgical area to the extent required for the patient's safety and for microscopic visualization.
