ALERT: The exclamation point within an equilateral triangle is intended to alert the user of the presence of important operating and maintenance (servicing) instruction s in the literature accompanying the component.
1. READ ALL INSTRUCTIONS: All the safety and operating instructions of your Cary Audio 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 WARNING: All warnings on the unit and in the operating instructions should be adhered to.
4. FOLLOW INSTRUCTIONS: All operating and use instructions should be followed.
5. CLEANING: Unplug the unit from the wall outlet before cleaning. The unit should be cleaned only as recommended by the manufacturer.
6. ATTACHMENTS: Do not use attachments not recommended by the unit manufacturer as they may cause hazards.
7. WATER AND MOISTURE: Do not use the unit near water - for example, near a bath tub, wash bowl, kitchen sink, or laundry tub; in a wet basement; or near a swimming pool.
8. ACCESSORIES: Do not place the unit on an unstable cart, stand, tripod, bracket, or table. The unit may fall, causing serious injury to a child, an adult, or da m a ge to the unit. Mounting of the unit should fol low the manufacturer's instructions and should use a mounting accessory recommended by the manufactur er.
9. VENTILATION: Slots and openin g s in the cabinet are provided for ventilation to ens ure reliable operation of the unit and to protect it from overheating. These openings must not be blocked or covered. The top or bottom panel openings should never be blocked by placing the unit on a bed, sofa, rug, or other similar surface. The unit should not be installed in a built-in location such as a bookcase or rack unless proper ventilation is pro vid ed. There should be free space of at least 6 inches (16cm) above the unit and an opening behind the unit.
10. GROUNDING OR POLARIZATION: The unit may be equipped with a polarized alternating current line plug (a plug having one blade wider than the other). This plug will fit into the power outlet only one way. This is a safety feature. If you cannot insert the plug fully into the outlet, try reversing the plug. If the plug should fail to fit, contact a licensed electrician to replace your obsolete ou tlet. Do not defeat the safety purpose of the polarized plug.
11. POWER SOURCES: The unit should be operated only from the type of power source indicated on the marking label. If you are not sure of the type of power supplied to your home, consult your unit dealer or local power company.
12. POWER CORD PROTECTION: Power supply cords should be routed so that they are unlikely to be walked on or pinched by items placed on or against them. Pay close attention to cords where they enter a plug, or a convenience receptacle, and the point where they exit from the unit.
13.
OUTDOOR ANTENNA GROUNDING: If an outside antenna or cable system is connected to the unit, be sure the antenna or cable system is grounded so as to provide protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code, NSI/NFPA 70, provides information regarding proper grounding of the mast and supporting structure, grounding of the lead-in wire to an Antenna-discharge unit, size of grounding conductors, location of antenna-discharge u nit, connection to grounding electrodes, and requirements for the grounding electrode.
IMPORTANT SAFETY INSTRUCTIONS
14. LIGHTNING: For added protection for the unit during a lightning storm, or when it is left unattended and unused for long periods of time, unplug it from the wall outlet and disconnect the antenna or cable system. This will prevent damage to the unit due to lightning and power line surges.
15. POWER LINES: An outside antenna system should not be locat e d in the vicinity of overhead power lines or other electric light or power circuits, or where it can fall into such power lines or circuits. When insta lling an outside antenna system, take extreme care to keep from touc hing such power lines or circuits as contact with them mig ht be fatal.
16. OVERLOADING: Do not overload wall outlets, extension cords, or integral convenience receptacles as this can result in a risk of fire or electric shock.
17. OBJECT AND LIQUID ENTRY: Never push objects of any kind into the unit through openings as they may touch dangerous voltage points or short-out parts that could result in a fire or electric shock. Never spill liquid of any kind on the unit.
18. SERVICING: Do not attempt to service the unit yourself as opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel.
19. REPLACEMENT PARTS: When replacement parts are required, be sure the service technician has used replacement parts specified by the manufacturer or have the same characteristics as the original part. Unauthorized substitutions may result in fire, electr ic shock or other hazards.
20. SAFETY CHECK: Upon completion of any service or repa irs t o the unit, ask the service technician to perform safety checks to determine that the unit is in proper operating condition.
21. WALL OR CEILING MOUNTING: The unit should be mounted to a wall or ceiling only as recommended by the manufacturer.
22. HEAT: The unit should be situated away from heat sources such as radiators, heat registers, stoves, or other units (including amplifiers) that produce heat.
23. IMPORTANT SAFETY NOTE: Before connecting a new component such as the DVD 7 to your audio or hom e
theater system it is always good practice to make certain that all components are turned off, and preferably unplugged from their AC power source. Many modern electronics products feature automatic turn-on circuits that may be activated during an installation, causing the potential for damage to electronic c omponents and/or speakers. Such damage is not covered by product warranties and Cary Audio specifically disclaims responsibility for any such damage.
Power Cord: The removable power cord that is shipped with the player is specifically designed to be used with this product. Other AC cords may be used, so consult your dealer for advice on AC power cords and high quality wire in your system.
Wiring: Cables that run inside of walls should have the appropriate markings to indicate compliance with, and listing by the UL, CSA or other standards required by the UL, CSA, NEC or your local building code. Questions about cables inside of walls should be referred to a qualified custom installer, or a licensed electrician or low-voltag e contractor.
Do Not Open the Cabinet: There are no user serviceable components inside this product. Opening the cabinet may present a shock hazard, and any modification to the product will void your warranty. If water or any m e tal object, such as a paper clip, coin, or staple accidentally falls inside the unit, disconnect it from the AC power source immediately and contact Cary Audio for further instructions.
24.
RECORDING COPYRIGHT: Recording of copyrighted material for other than personal use is illegal without permission of the copyright holder.
25. NOTE TO CATV SYSTEM INSTALLER: This reminder is provid ed to call the CATV system installer's attention to article 820-40 of the NEC, ANSI/NFPA 70, which provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical.
AC Fuse: The fuse is located inside the chassis and is not user serviceable. If power does not come on, contact your authorized service representative.
