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 reli-

able 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 ap-

pliance should not be placed in a built-in instal-

lation 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 indi-

cated on the marking label. If you are not sure

of the type of power supply to your home, con-

sult your appliance dealer or local power com-

pany.

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 fea-

ture. 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 electri-

cian to replace your obsolete outlet. Do not de-

feat 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.

FIGURE 1:

EXAMPLE OF ANTENNA GROUNDING AS PER NA-

TIONAL ELECTRICAL CODE, ANSI/NFPA 70

14. Outdoor Antenna Grounding – If an outside

antenna or cable system is connected to the ap-

pliance, 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-dis-

charge unit, connection to grounding elec-

trodes, 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 over-

head power lines or other electric light or

power circuits, or where it can fall into such

power lines or circuits. When installing an out-

side 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 recep-

tacles as this can result in a risk of fire or elec-

tric 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 follow-

ing conditions:

A. When the power-supply cord or plug is

damaged,

B. If liquid has been spilled, or objects have

fallen into the appliance,

Memory Preservation

This unit does not require memory preservation

batteries. A built-in memory power back-up sys-

tem preserves the contents of the memory dur-

ing power failures and even when the unit is un-

plugged. The unit must be plugged in order to

charge the back-up system.

The memory preservation period after the unit

has been unplugged varies depending on climate

and placement of the unit. On the average,

memory contents are protected over a period of

a few weeks after the last time the unit has been

unplugged. This period is shorter when the unit

is exposed to a highly humid climate.

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 non-

compressed high-quality audio data. The MP3 format, widely used over the Internet, accomplishes data

compression at near-CD sound quality.
