PRECAUTIONS

Read the Operating Instructions carefully and completely before operating the unit. Be sure to keep the Operating Instructions for future reference. All warnings and cautions in the Operating Instructions and on the unit should be strictly followed, as well as the safety suggestions below.

Installation

1Water and moisture — Do not use this unit near water, such as near a bathtub, washbowl, swimming pool, or the like.

2Heat — Do not use this unit near heat sources, including heating vents, stoves, or other appliances that generate heat. It also should not be placed in temperatures less than 5°C (41“F)or higher than 35°C (95°F).

3Mounting surface — Place the unit on a flat, even surface.

4Ventilation — The unit should be situated with adequate space around it so that proper heat ventilation is assured. Allow 10 cm (4 in.) clearance from the rear and the top of the unit, and 5 cm (2 in.) from each side.

-Do not place the unit on a bed, rug, or similar surface that may block the ventilation openings.

-Do not install the unit in a bookcase, cabinet, or airfight rack where ventilation may be impeded.

5Objects and liquid entry —Takecare that objects or liquids do not get inside the unit through the ventilation openings.

6Carts and stands — When placed or mounted on a stand or cart, the unit should be moved with care.

Quick stops, excessive force, and uneven surfaces may cause the unit or cart to overturn or fall.

7Wall or ceiling mounting — The unit should not be mounted on a wallor-ceiling,unless specified in the Operating Instructions.

Electric Power

1Power sources — Connect this unit only to power sources specified in the Operating Instructions, and as marked on the unit.

2Polarization — As a safety feature, some units are equipped with polarized AC power plugs which can only be inserted one way into a power outlet. If it is difficult or impossible to insert the AC power plug into an outlet, turn the plug over and try again. If it is not still inserted easily into the outlet, please call a qualified service technician to service or replace the outlet, To avoid defeating the safety feature of the polarized plug, do not force it into a power outlet.

3AC power cord

-When disconnecting the AC power cord, pull it out by the AC power plug. Do not pull the cord itself.

-Never handle the AC power plug with wet hands, as this could result in fire or shock.

-Power cords should be firmly secured to avoid being severely bent, pinched, or walked upon. Pay particular attention to the cord from the unit to the power socket.

-Avoid overloading AC power plugs and extension cords beyond their capacity, as this could result in fire or shock.

4Extension cord — To help prevent electric shock, do not use a polarized AC power plug with an extension cord, receptacle, or other outlet unless the polarized plug can be completely inserted to prevent exposure of the blades of the plug.

1 ENGLISH

5When not in use — Unplug the AC power cord from the AC power plug if the unit will not be used for several months or more. When the cord is plugged in, a small amount of current continues to flow to the unit, even when the power is turned off

Outdoor Antenna

1Power lines — When connecting an outdoor antenna, make sure it is located away from power lines.

2Outdoor antenna grounding — Be sure the antenna system is properly grounded to provide protection against unexpected voltage surges or static electricity build-up.Article 810 of the National Electrical Code, ANS1/NFPA70, provides information on proper grounding of the mast, supporting structure, and thelead-inwire to the antenna discharge unit, as well as the size of the grounding unit, connection to grounding terminals, and requirements for grounding terminals themselves.

-the front speaker cords to the FRONT SPEAKERS terminals

-the center speaker cord to the CENTER SPEAKER terminals

-the surround speaker cords to the SURROUND SPEAKERS terminals.

For more powerful bass, connect a sub woofer with a built-inamplifier to the SUPER WOOFER d jack.

Speaker impedance

Front and center speakers

The SPEAKER IMPEDANCE SELECTOR on the rear should be set to the position that matches the impedance value of the front and center speakers.

When using 4 ohm speakers, set the selector to 4Q. When using 8 ohm speakers, set the selector to 8Q. Please unplug the AC cord before setting the selector.

Surround speakers and super woofer

The SPEAKER IMPEDANCE SELECTOR has no effect on the SURROUND SPEAKERS terminals and the SUPER WOOFER ~ jack. For the surround speakers and sub woofer, use speakers of 8 ohms or more.

Connecting + to +, -to- terminals

To get the proper sound effect, the speaker terminals on the unit and the speaker should be connected with proper polarity; the + terminal on the unit should be connected to the + terminal on the speaker (and – to –).

m

Be sure to connect the speaker cords correctly as shown in the illustration on the right column. Improper connections can cause shorl circuits in the SPEAKER(S) terminals.

Do not leave objects generating magnetism near the speakers.

When using a sub woofer, select the speaker system A (see page 6). Otherwise no sound can be heard from it.

POSITIONING THE SPEAKERS

Position the speakers to make the most of the Dolby Pro Logic or DSP effect (see “DOLBYPRO LOGIC).

@Front speakers

@Center speaker
