Read these instructions carefully and completely before using the product
1. This equipment is intended to be connected to other equipment thus forming a Medical Electrical System. External equipment intended for connection to signal input, signal output or other connectors must comply with the relevant product standard e.g. IEC 60950-1 for IT equipment and the IEC 60601series for medical electrical equipment. In addition, all such combinations – Medical Electrical Systems – must comply with the safety requirements stated in the general standard IEC 60601-1, (edition 3.1), clause 16. Any equipment not complying with the leakage current requirements in IEC 60601-1 must be kept outside the patient environment i.e. at least 1.5m from the patient support or must be supplied via a separation transformer to reduce the leakage currents. Any person who connects external equipment to signal input, signal output or other connectors has formed a Medical Electrical System and is therefore responsible for the system to comply with these requirements. If in doubt, contact a qualified medical technician or your local representative. When the instrument is connected to a PC, or other similar items, beware of not touching the PC and patient simultaneously. 2. A Separation Device (isolation device) is needed to isolate the equipment located outside the patient environment from the equipment located inside the patient environment. In particular such a Separation Device is required when a network connection is made. The requirement for the Separation Device is defined in IEC 60601-1 clause 16. 3. To avoid the risk of electric shock, this equipment must only be connected to supply mains with a protective earth. 4. Do not use any additional multiple socket-outlet or extension cord. For safe setup please refer to section 2.3 5. No modification of this equipment is allowed without the authorization of Interacoustics. Interacoustics will make available on request circuit diagrams, component part lists, descriptions, calibration instructions, or other information. This will assist service personnel to repair, the parts of this audiometer that are designated by the Interacoustics service personnel as repairable. 6. For maximum electrical safety, turn off the power to a mains- powered instrument when it is left unused.

7. The instrument is not protected against ingress of water or other liquids. If any spillage occurs, check the instrument carefully before use or return for service. 8. No part of the equipment can be serviced or maintained while in use with the patient. 9. Do not use the equipment if it is showing visible signs of damage.
1. Never insert, or in any way use, the insert headset without a new clean and non-defective test tip. Always make sure that the foam or ear-tip is mounted correctly. Ear tips and foam are for single use only. 2. The instrument is not intended for use in environments exposed to fluid spills. 3. The instrument is not intended for use in oxygen rich environments or for use in conjunction with flammable agents. 4. Check calibration if any parts of the equipment are exposed to shock or rough handling. 5. Components marked for “single use” are intended for a single patient during a single procedure, and there is a risk of contamination if the component is re-used. 6. Do not switch the power on/off for the Eclipse device while a patient is connected. 7. The specifications for the device are valid if the device is operated within the environmental limits. 8. When connecting the device to its accessories, use only the dedicated socket as described in the section “Eclipse back panel”. If the wrong socket is selected for the transducer, the stimulus sound pressure level (SPL) will not meet the calibrated level as set in the user interface and this could lead to an incorrect diagnosis. 9. To ensure safe operation and valid measurements, the Eclipse device and its accessories must be checked and calibrated at least once a year or more frequently, if required by local regulations or if there is any doubt about correct Eclipse device function. 10. Use only sound stimulation intensities that will be acceptable to the patient. 11. It is recommended that parts which are in direct contact with the patient (e.g. the probe) are subjected to standard infection control procedures between testing patients. Please refer to cleaning section 12. Ensure that the right/left transducer is connected to the corresponding ear of the patient and that the correct test ear is selected from within the user interface.
NOTICE
1. To prevent system faults take appropriate precautions to avoid PC viruses and similar. 2. Use only transducers calibrated with the actual instrument. To identify a valid calibration, the serial number for the instrument will be marked on the transducer. 3. Although the instrument fulfils the relevant EMC requirements, precautions should be taken to avoid unnecessary exposure to electromagnetic fields, e.g. from mobile phones etc. If the device is used adjacent to other equipment, it must be monitored to ensure that there is no mutual disturbance. Please also refer to EMC considerations in section 11.7 4. Use of accessories, transducers and cables other than specified, with the exception of transducers and cables sold by Interacoustics or representatives, may result in increased emission or decreased immunity of the equipment. For a list of accessories, transducers and cables that fulfil the requirements please refer to section 1.3 5. Within the European Union, it is illegal to dispose of electric and electronic items in unsorted municipal waste. Electric and electronic waste may contain hazardous substances and therefore has to be collected separately. Such products will be marked with the crossed-out wheeled bin symbol, shown below. The cooperation of the user is important in order to ensure a high level of reuse and recycling of electric and electronic waste. Failing to recycle such waste products in an appropriate way may endanger the environment and consequently the health of human beings. 6. Outside the European Union, local regulations should be followed when disposing of the product after end of life. 7. The LBK15 unit is not valid for performing a functional check of ASSR and ABRIS due to the nature of ASSR algorithms. For functional testing (detection of false passes), a patient must be connected with electrodes, in the absence of a stimulus (disconnected transducer).
