Safety Notes
!
WARNING
The GSI 39 is designed for compliance to IEC and UL 60601-1 when used in the patient vicinity. To achieve this compliance, use of hospital grade plug and receptacles are required. For patient and operator safety, the GSI 39 must be used with properly grounded plug and receptacles at all times. The GSI 39 is equipped with a specific power transformer (ref: 113-405800), which should not be interchanged with any other transformer or supply. Any program aimed at obtaining reliable records of hearing thresholds should be staffed and supervised by appropriately-trained individuals. Latex is not used any where in the manufacturing process. The base material for the earphone cushions is made from natural and synthetic rubber. The material used to manufacture GSI’s eartips is Krayton Thermoplastic Rubber.

WARNING
This symbol indicates the location of a service adjustment part and is intended for service personnel only. The GSI 39 is a specifically calibrated audiometer and Tympanometer, and the periodic service and adjustments for the instrument that may be required should be done only by an authorized GSI service technician. Please read the entire manual prior to using the GSI 39 to become familiar with the test functions and proper accessory connections. Accessory equipment connected to the analog and digital interfaces must be certified to the respective IEC standards (IEC950 for data processing or IEC 60601-1 for medical equipment). Furthermore, all configurations shall comply with the system standard IEC 60601-1-1. Everyone who connects additional equipment to the signal input or signal output port configures a medical system, and is therefore responsible that the system complies with the requirements of the system standard IEC60601-1-1. If in doubt, consult the technical service department or a local GSI representative.

Customer Responsibility
!
WARNING
This product and its components will perform reliably only when operated and maintained in accordance with the instructions contained in this manual, accompanying labels, and/or inserts. A defective product should not be used. Parts which may be broken or missing or are plainly worn, distorted or contaminated should be replaced immediately with clean, genuine replacement parts manufactured by or available from GSI. The responsibility of GSI for a malfunction product is limited by the warranty set forth in this manual. Should repair or replacement of this product become necessary after the warranty period, the customer should seek advice from GSI Technical Support prior to such repair or replacement. If this product is in need of repair, it should not be used until all repairs have been made and the unit is functioning properly and ready for use. The owner of this product has sole responsibility for any malfunction resulting from improper use or maintenance, or repair by anyone other than GSI, and from any malfunction caused by parts that are damaged or modified by anyone other than GSI. This product should not be used in the presence of fluid that can come into contact with any of the electronic components or wiring. Should the user suspect fluids have contacted the system components or accessories, the unit should not be used until deemed safe by a GSI certified service technician. Do NOT use in the presence of flammable gaseous mixtures. Users should consider the possibility of explosions or fire when using this device in close proximity to flammable anesthetic gases. Periodically, have a service technician perform electrical safety checks on the unit in order to show continued compliance to IEC and UL 60601-1.

Preface
Safety Precautions The following safety precautions must be observed at all times. General Safety precautions must be followed when operating electrical equipment. Failure to observe these precautions could result in damage to the equipment and injury to the operator or patient. The employer should instruct each employee in the recognition and avoidance of unsafe conditions and the regulations applicable to his or her work environment to control or eliminate any hazards or other exposure to illness or injury. It is understood that safety rules within individual organizations vary. If a conflict exists between the material contained in this manual and the rules of the organization using this instrument, the more stringent rules should take precedence. This device should only be used by hearing health care professionals such as an audiologist, otolaryngologist, researcher or a technician under the direct supervision by the fore mentioned specialist. User should use their professional skills when interpreting the results and this should be done in conjunction with other testing as deemed appropriate given their professional skills. The maximum sound levels that can be generated by the system can cause serious injury to the ear. Before attaching the earphones to the patient, ensure that: a. The system is running. b. The hearing levels in the test set to be used are appropriate. c. A biologic check of the stimulus has been performed by the operator. The customer is responsible for maintaining all system software in a safe, secure location. Do not use extension cords with this instrument or for the Isolation Box. Extension cords can cause ground integrity and impedance problems. In addition to electrical safety considerations, poorly earthed mains power outlets could cause inaccurate test results due to the introduction of electrical interference from the mains. ANY EQUIPMENT CONNECTED TO THE GSI INSTRUMENT AND USED IN THE PATIENT VICINITY MUST BE POWERED BY AN ISOLATED POWER SOURCE TO MAINTAIN THE ELECTRICAL SAFETY OF THE OVERALL SYSTEM. The isolated power source can be purchased directly from GSI, or elsewhere when approved for use by GSI.
Cautions - General
If the system is not functioning properly, do not operate it until all necessary repairs are made and the unit is test and calibrated for proper functioning in accordance with Grason-Stadler published specifications. Equipment is not user repairable. Repairs and battery replacement must be performed by a qualified service representative only.

GSI 39
Warning - Connecting Additional Equipment Accessory equipment connected to the analog and digital interfaces must be certified to the respective IEC standards (IEC 950 f or data processing or IEC 60601-1 for medical equipment and/or appropriate European Directives). Furthermore, all configurations shall comply with the system standard IEC 60601-1-1. Everyone who connects additional equipment to the signal input or signal output port configures a medical system, and is therefore responsible for the system compliance with the requirements of the system standard IEC 60601-1-1. If in doubt, consult the technical service department or your local representative. Connect all nonmedical equipment to the GSI Isolated Power Supply. The AC power outlets on the isolation transformer/power box a re intended for use with GSI approved components only. Use of any other equipment may result in damage to the power unit. Follow all safety standards set by each place of employment. NOTE: If the instrument is connect to a PC, power to the monitor and computer must be controlled by the isolation transformer. Always leave the monitor and computer power switches in the ON position and control power from the isolation transformer. Always turn OFF system power before connecting or disconnecting system components to help guard against personal injury.
Warning - Electric Shock Hazards
Do not open the case of the GSI instrument. Do not remove any GSI instrument covers. Refer servicing to qualified personnel.
Warning - Electric Grounding
This device uses a three wire power cord with a hospital grade plug (for international applications, IEC 601-1 approved plug). The chassis is earth grounded. For grounding reliability, connect the device to a hospital grade or hospital only receptacle (for international applications, IEC 601-1 approved receptacle). Inspect the power cord often for fraying or other damage. Do not operate the apparatus with a damaged power cord or plug. Improper grounding is a safety hazard. Periodically check the system ground integrity.
Warning - Explosion
This system is not explosion proof. Do not use in the presence of flammable anesthetics or other gases.
Warning - Connections
Do not switch on any system power until all cables have been properly connected and verified. See this manual for setup instructions, which accompanies all deliveries of the system. Switch off the system power before connecting or disconnecting any system component(s) or accessories. This may damage the device(s).
Warning - General
Proper use of this device depends on careful reading of all instructions and labels. Follow all safety standards set by each place of employment.
