turer.

9. An appliance and cart combination should be moved with care. Quick stops, excessive force, and uneven surfaces may cause the appliance and cart combination to overturn.

10. Ventilation – Slots and openings in the cabinet are provided for ventilation and to ensure reliable operation of the appliance and to protect it from overheating, and these openings must not be blocked or covered. The openings should never be blocked by placing the appliance on a bed, sofa, rug, or other similar surface. The appliance should not be placed in a built-in installation such as a bookcase or rack unless proper ventilation is provided. There should be free space of at least 20 cm (8 in.) and an opening behind the appliance.

11. Power Sources – The appliance should be op- erated only from the type of power source indicated on the marking label. If you are not sure of the type of power supply to your home, consult your appliance dealer or local power company.

12. Grounding or Polarization – The appliance 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 are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug.

13. Power-Cord Protection – Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the appliance.

Important Safeguards

14. Outdoor Antenna Grounding – If an outside antenna or cable system is connected to the appliance, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information with regard to 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 unit, connection to grounding electrodes, and requirements for the grounding electrode. See Figure 1.

15. Lightning – For added protection for the appli- ance 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 appliance due to lightning and power-line surges.

16. Power Lines – An outside antenna system should not be located 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 installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them might be fatal.

17. Overloading – Do not overload wall outlets, extension cords, or integral convenience receptacles as this can result in a risk of fire or electric shock.

18. Object and Liquid Entry – Never push ob- jects of any kind into the appliance 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 appliance.

19. Servicing – Do not attempt to service the appli- ance yourself as opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel.

20. Damage Requiring Service – Unplug the ap- pliance form the wall outlet and refer servicing to qualified service personnel under the following conditions: A. When the power-supply cord or plug is

damaged,

B. If liquid has been spilled, or objects have

fallen into the appliance,

C. If the appliance has been exposed to rain or

water,

D. If the appliance does not operate normally

by following the operating instructions. Adjust only those controls that are covered by the operating instructions as an improper adjustment of other controls may result in damage and will often require extensive work by a qualified technician to restore the appliance to its normal operation,

E. If the appliance has been dropped or dam-

aged in any way, and

F. When the appliance exhibits a distinct

change in performance – this indicates a need for service.

21. 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, electric shock, or other hazards.

22. Safety Check – Upon completion of any ser- vice or repairs to the appliance, ask the service technician to perform safety checks to determine that the appliance is in proper operation condition.

23. Wall or Ceiling Mounting – The appliance should be mounted to a wall or ceiling only as recommended by the manufacturer.

24. Heat – The appliance should be situated away from heat sources such as radiators, heat registers, stoves, or other appliances (including amplifiers) that produce heat.

25. Liquid Hazards – The appliance shall not be exposed to dripping or splashing and no objects filled with liquids, such as vases shall be placed on the appliance.

Connecting the NAC-2.3

Connecting for listening to Internet radio and the Audio Network Server

Listening to Internet radio stations requires the following:

■ Modem (a device that provides Internet connections via leased lines; e.g., a cable modem, xDSL modem, terminal adapter)

* To have access to Internet, you typically need to make a contract with an Internet service provider

(ISP). Modem requirements differ from ISP to ISP; for detailed information, consult with your ISP or PC retailer.

■ Router (gateway) (gateway) (a device that enables multiple PCs or devices to connect to the Internet simultaneously)

An IP address can be obtained automatically by using the router’s DHCP function.

* Some routers have built-in modem functionality. Router requirements differ from ISP to ISP; for

detailed information, consult with your ISP or PC retailer.

■ Ethernet CAT-5 cable

■ Minimum Internet Connection Requirements:

• Broadband Internet Connection

• DHCP (Dynamic Host Configuration Protocol) based network (requires a DHCP-enabled router)

• 100Base-TX switch built-in broadband router (recommended)

Connecting for listening to both Internet radio stations and music files saved on Audio Network Server such as NAS-2.3 requires setting up the Audio Network Server as well as completing connections and meeting the requirements described above.

What is Audio Network Server with Net-Tune System Protocol?

Audio Network Server streams digitally recorded music files over a LAN so that they can be played by NAC-2.3 functionality. One server can stream to multiple units of NAC-2.3 at the same time.

The music streaming service is build on Onkyo’s proprietary NTSP protocol, which is an extension to TCP/IP, thereby providing high response times.

In addition to providing the music streaming server functionality, the Audio Network Server allows you to automatically searches music files saved on its hard disk, then easily register the files with the server.

Supported music formats include WAVE (PCM) and MP3. The WAVE (PCM) format provides noncompressed high-quality audio data. The MP3 format, widely used over the Internet, accomplishes data compression at near-CD sound quality.
