GENERAL HANDLING PRECAUTIONS This device is intended for use only by qualified medical personnel. Use only Nihon Kohden approved products with this device. Use of non-approved products or in a non-approved manner may affect the performance specifications of the device. This includes, but is not limited to, batteries, recording paper, pens, extension cables, electrode leads, input boxes and AC power. Please read these precautions thoroughly before attempting to operate the instrument. 1. To safely and effectively use the instrument, its operation must be fully understood. 2. When installing or storing the instrument, take the following precautions: (1) Avoid moisture or contact with water, dust, extreme atmospheric pressure, excessive humidity and temperatures, poorly ventilated areas, and saline or sulphuric air. (2) Place the instrument on an even, level floor. Avoid vibration and mechanical shock, even during transport. (3) Avoid placing in an area where chemicals are stored or where there is danger of gas leakage. (4) The power line source to be applied to the instrument must correspond in frequency and voltage to product specifications, and have sufficient current capacity. (5) Choose a room where a proper grounding facility is available. 3. Before Operation (1) Check that the instrument is in perfect operating order. (2) Check that the instrument is grounded properly. (3) Check that all cords are connected properly. (4) Pay extra attention when the instrument is in combination with other instruments to avoid misdiagnosis or other problems. (5) All circuitry used for direct patient connection must be doubly checked. (6) Check that battery level is acceptable and battery condition is good when using battery-operated models. 4. During Operation (1) Both the instrument and the patient must receive continual, careful attention. (2) Turn power off or remove electrodes and/or transducers when necessary to assure the patient’s safety. (3) Avoid direct contact between the instrument housing and the patient. 5. To Shutdown After Use (1) Turn power off with all controls returned to their original positions. (2) Remove the cords gently; do not use force to remove them. (3) Clean the instrument together with all accessories for their next use. 6. The instrument must receive expert, professional attention for maintenance and repairs. When the instrument is not functioning properly, it should be clearly marked to prevent use while it is out of order. 7. The instrument must not be altered or modified in any way. 8. Maintenance and Inspection (1) The instrument and parts must undergo regular maintenance inspection at least every 6 months. (2) If stored for extended periods without being used, make sure prior to operation that the instrument is in perfect operating condition. Operator’s Manual EEG-1200

(3) Technical information such as parts list, descriptions, calibration instructions or other information is available for qualified user technical personnel upon request from your Nihon Kohden representative. 9. When the instrument is used with an electrosurgical instrument, pay careful attention to the application and/or location of electrodes and/or transducers to avoid possible burn to the patient. 10. When the instrument is used with a defibrillator, make sure that the instrument is protected against defibrillator discharge. If not, remove patient cables and/or transducers from the instrument to avoid possible damage.
WARRANTY POLICY Nihon Kohden Corporation (NKC) shall warrant its products against all defects in materials and workmanship for one year from the date of delivery. However, consumable materials such as recording paper, ink, stylus and battery are excluded from the warranty. NKC or its authorized agents will repair or replace any products which prove to be defective during the warranty period, provided these products are used as prescribed by the operating instructions given in the operator’s and service manuals. No other party is authorized to make any warranty or assume liability for NKC’s products. NKC will not recognize any other warranty, either implied or in writing. In addition, service, technical modification or any other product change performed by someone other than NKC or its authorized agents without prior consent of NKC may be cause for voiding this warranty. Defective products or parts must be returned to NKC or its authorized agents, along with an explanation of the failure. Shipping costs must be pre-paid. This warranty does not apply to products that have been modified, disassembled, reinstalled or repaired without Nihon Kohden approval or which have been subjected to neglect or accident, damage due to accident, fire, lightning, vandalism, water or other casualty, improper installation or application, or on which the original identification marks have been removed. In the USA and Canada other warranty policies may apply.
CAUTION United States law restricts this product to sale by or on the order of a physician.

EMC RELATED CAUTION This equipment and/or system complies with IEC 60601-1-2 International Standard for electromagnetic compatibility for medical electrical equipment and/or system. However, an electromagnetic environment that exceeds the limits or levels stipulated in IEC 60601-1-2, can cause harmful interference to the equipment and/or system or cause the equipment and/or system to fail to perform its intended function or degrade its intended performance. Therefore, during the operation of the equipment and/or system, if there is any undesired deviation from its intended operational performance, you must avoid, identify and resolve the adverse electromagnetic effect before continuing to use the equipment and/or system. The following describes some common interference sources and remedial actions: 1. Strong electromagnetic interference from a nearby emitter source such as an authorized radio station or cellular phone: Install the equipment and/or system at another location. Keep the emitter source such as cellular phone away from the equipment and/or system, or turn off the cellular phone. 2. Radio-frequency interference from other equipment through the AC power supply of the equipment and/or system: Identify the cause of this interference and if possible remove this interference source. If this is not possible, use a different power supply. 3. Effect of direct or indirect electrostatic discharge: Make sure all users and patients in contact with the equipment and/or system are free from direct or indirect electrostatic energy before using it. A humid room can help lessen this problem. 4. Electromagnetic interference with any radio wave receiver such as radio or television: If the equipment and/or system interferes with any radio wave receiver, locate the equipment and/or system as far as possible from the radio wave receiver. 5. Interference of lightning: When lightning occurs near the location where the equipment and/or system is installed, it may induce an excessive voltage in the equipment and/or system. In such a case, disconnect the AC power cord from the equipment and/or system and operate the equipment and/or system by battery power, or use an uninterruptible power supply. 6. Use with other equipment: When the equipment and/or system is adjacent to or stacked with other equipment, the equipment and/or system may affect the other equipment. Before use, check that the equipment and/or system operates normally with the other equipment. 7. Use of unspecified accessory, transducer and/or cable: When an unspecified accessory, transducer and/or cable is connected to this equipment and/or system, it may cause increased electromagnetic emission or decreased electromagnetic immunity. The specified configuration of this equipment and/or system complies with the electromagnetic requirements with the specified configuration. Only use this equipment and/or system with the specified configuration.
