NOTICE - IMPORTANT SAFETY INFORMATION CAUTIONRISK OF ELECTRIC SHOCK DO NOT OPEN ! ! WARNING: TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THIS EQUIPMENT TO RAIN OR MOISTURE. 1.READ INSTRUCTIONS All the safety and operating instructions of your Hafler equipment should be read before power is applied to the equipment. 2.RETAIN OWNER'S MANUAL These safety and operating instructions should be retained for future reference. 3.HEED WARNINGS All warnings on the equipment and in the operating instructions are important and should be followed. 4.FOLLOW INSTRUCTIONS All operating and use instructions are important and should be followed. 5.HEAT The equipment should be kept away from areas of high tempera- ture, i.e., heater vents, radiators, stoves/ovens, fireplaces, etc. 6.VENTILATION The equipment should be used in an area suitable for proper ventilation. Care should be taken not to impede airflow in and around the cabinet. 7.WATER AND MOISTURE The equipment should not be used in or around water, such as a bathtub, sink, or swimming area. Also, the equipment should not be used in areas prone to flooding, such as a basement. 8.POWER SOURCES The equipment should be connected only to a power source of the same voltage and frequency as that listed on the rear panel above the power cord entry point. 9.POWER CORD PROTECTION Power cords should be arranged so they do not interfere with the movement of objects in the room: people, fan blades, utility carts, etc. Also, care should be taken that the cord is not pinched or cut, and placed so it is not in danger of being pinched or cut, as in under a rug, around a tight corner, etc. 10.POWER CORD GROUNDING The power supply cord is of a three wire grounded type, designed to reduce the risk of electric shock sustained from a live cabinet. It is assumed to be of suitable length for most uses of the equipment. The use of extension cords and power strips is discouraged unless they are of suitable rating to deliver the required total current for safe operation of all connected equip- ment. Furthermore, extension cords or power strips must providethe same three wire grounded connection. It is important that the blades of the equipmentÕs plug be able to fully insert into the mating receptacle. Never remove the round grounding pin on the plug in an attempt to mate to a two wire ungrounded receptacle: use a grounding adaptor with the grounding tab or wire suitably connected to earth ground. 11.NON-USE PERIODS During periods of extended non-use, the power cord should be unplugged from the power source. 12.CLEANING The equipment should be cleaned only as detailed in the operat- ing instructions. 13.OBJECT AND LIQUID ENTRY Care should be taken so that objects and/or liquids, such as cleaning fluids or beverages, are not spilled into the enclosure of the equipment. 14.DAMAGE REQUIRING SERVICE Hafler equipment should be serviced by qualified service person- nel when: A. The power supply cord or plug has been damaged, or B. Objects have fallen, or liquid has been spilled into the equipment, or C. The equipment has been exposed to rain, or D. The equipment does not appear to operate normally or exhibits a marked change in performance, or E. The equipment has been dropped, or the enclosure has been damaged. 15.SERVICING The user should not attempt to service the equipment beyond that which is described in the operating instructions. All other service should be referred to qualified service personnel. 16.CARTS AND STANDS The equipment should be used with carts or stands only of sufficient strength and stability for the use intended. An equipment and cart combination should be moved with care. Quick stops and starts, excessive force, and uneven surfaces may cause the equipment and cart combination to topple. Ð i Ð The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure, that may be of sufficient magni- tude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user of the presence of important operating and maintenance (servic- ing) instructions in the literature accompanying the appliance.
