2 Safety notes 2.4 Responsibilities and duties of the operator
Additional equipment connected to medical electrical equipment must demonstrably comply with the applicable IEC or ISO standards (e.g. IEC 60950-1 for data processing equipment). Furthermore all configurations must comply with the normative requirements for medical systems (see IEC 60601-1-1 or section 16 of IEC 60601-1). If you connect additional devices to medical electrical systems, you are a system configurer and are thus responsible for ensuring that the system complies with the normative requirements for systems.
2.3.1 Notification to manufacturers and authorities In member states of the European Union, the responsible organization or person must report serious incidents to his competent authority. In all other countries, comparable rules apply where national legislation so requires.
2.4 Responsibilities and duties of the operator Electrical safety u
Switch the device off every time before disconnecting it from the power supply, or if you are not going to use the device for any length of time.
u
Also switch off the device and disconnect it from the power supply before cleaning surfaces or accessories with a damp cloth.
u
Use only cables and plugs which are in perfect working condition.
u
Connect the device only to a power supply that corresponds to the values specified on the rating plate.
u
Never pull the cable to disconnect the plug.
u
Do not use multiple sockets.
u
Do not use extension cables.
u
Observe the instructions regarding electromagnetic compatibility (EMC).
u
Set the device up so that the power cable can be disconnected from the power supply quickly and without any supplementary means.
u
Connect the device using the power cable intended for use with the device. If the device is mounted on an instrument table qualified by Carl Zeiss Meditec, it will be powered through this table.
u
Perform the electrical installation in conformance to IEC 60364-7-710 or the applicable national regulations. This includes the integration of a ground fault circuit interrupter (GFCI).
u
Do not touch the patient and the connections of the device simultaneously.

2 Safety notes 2.4 Responsibilities and duties of the operator
Documentation set SL 800
The SL 800 is a device of protection class II. The third wire in the power connection cable is only a functional earth wire. Live parts are accessible inside the device. If you remove the housing, you are exposed to the risk of an electric shock. u
Never open the device!
Ambient conditions u
Make sure that the installation requirements and the operation of the device meet the following requirements:
•
Low vibration
•
Clean environment
•
Avoid extreme mechanical loads
u
Do not operate or store the supplied devices in environmental conditions other than those prescribed.
u
Do not operate the supplied devices, when powered by electricity,
•
on easily inflammable materials,
•
in explosion risk areas (e.g. combustible mixture of anesthetic, cleaning or disinfecting agents with air, oxygen or nitrous oxide).
u
Do not store or use this device in damp areas. Do not expose the device to water splashes or dripping or sprayed water.
u
Ensure that no liquids can enter the device.
u
Protect all optical exits (e.g. projector mirror, front lens, binocular tube of stereomicroscope) against contamination and avoid touching optical exits.
Decommissioning u
If one of the following events should occur, disconnect the cable from the power supply, label the device clearly as being out of service and report the problem to the ZEISS Service:
•
Electric shock
•
Penetration of substances
•
Frequently occurring error messages
•
Faults that cannot be remedied based on the information provided in these instructions for use
If you use the device in combination with an accessory for image documentation, please note that if the sensor for laterality detection is defective, the right/left labeling of image data may be incorrect. In this case, inform ZEISS Service about the problem and check the right/left labeling of image data. Symbols and labels u
12 / 100
Observe the symbols and labels attached to the device.

2 Safety notes 2.5 Risk due to optical radiation
Transport u
Transport the device over long distances (e.g. move, return for repair, etc.) only in original packaging or special return packaging.
u
Contact your dealer or ZEISS Service.
2.5 Risk due to optical radiation This is a group 2 device according to ISO 15004-2 / ANSI Z80.36. The light emitted by this device is potentially hazardous. The longer the duration of exposure, the greater the risk of ocular damage. Exposure to light from this device when operated at maximum intensity will exceed the safety guideline for the aphakic eye after 48 s. Because prolonged intense light exposure can damage the retina, the use of the device for ocular examination should not be unnecessarily prolonged, and the brightness setting should not exceed what is needed to provide clear visualization of the target structures. Some groups of people will be at greater risk due to anatomical conditions (e.g. infants, aphakes and persons with diseased eyes). The risk may also be increased if the patient being examined has recently had any exposure to light (e.g. an eye examination or treatment). The time required to exceed the ISO 15004-2 guideline is reduced to 48 seconds if cold white VarioLight is used exclusively, compared with 88 seconds if warm white VarioLight is used exclusively.

Never look into the sun through the binocular tube and eyepieces.
2.6 Maintenance measures Maintenance procedures (maintenance and repairs) which are not specified in these instructions for use may only be carried out by persons authorized by Carl Zeiss Meditec and solely according to the service instructions issued by Carl Zeiss Meditec. For planning and implementing these maintenance and care procedures please contact ZEISS Service or your local dealer.
