Loading the batteries

The batteries included with the unit are to check initial operations; they may not last over a long period. We recommend using alkaline batteries that have a longer life.

•

Do not use or store batteries in direct sunlight or other excessively hot place, such as inside a car or near a heater. This can cause batteries to leak, overheat, explode or catch fire. It can also reduce the life or performance of batteries.

•

Incorrect use of batteries may result in such hazards as leakage and bursting. Observe the following precautions:

Never use new and old batteries together.

Insert the plus and minus sides of the batteries properly according to the marks in the battery case.

Batteries with the same shape may have different voltages. Do not use different batteries together.

When disposing of used batteries, please comply with governmental regulations or environmental public institution’s rules that apply in your country/area.

When inserting the batteries, make sure not to damage the springs on the battery’s (–) terminals. This can cause batteries to leak or overheat.

Operating range of remote control

The remote control may not work properly if:

•

There are obstacles between the remote control and the receiver’s remote sensor.

•

Direct sunlight or fluorescent light is shining onto the remote sensor.

•

The receiver is located near a device that is emitting infrared rays.

•

The receiver is operated simultaneously with another infrared remote control unit.

CAUTION

5.1 channel surround system:

Connecting your equipment

Placing the speakers

By connecting the left and right front speakers (L/R), the center speaker (C), the left and right surround speakers (SL/SR), and the subwoofer (SW), a 5.1 ch surround system can be enjoyed. To achieve the best possible surround sound, install your speakers as shown below.

120

Hints on the speaker placement

Where you put your speakers in the room has a big effect on the quality of the sound. The following guidelines should help you to get the best sound from your system.

•

The subwoofer can be placed on the floor. Ideally, the other speakers should be at about earlevel when you’re listening to them. Putting the speakers on the floor (except the subwoofer), or mounting them very high on a wall is not recommended.

•

For the best stereo effect, place the front speakers 2 m to 3 m apart, at equal distance from the TV.

•

If you’re going to place speakers around your CRT TV, use shielded speakers or place the speakers at a sufficient distance from your CRT TV.

•

If you’re using a center speaker, place the front speakers at a wider angle. If not, place them at a narrower angle.

•

Place the center speaker above or below the TV so that the sound of the center channel is localized at the TV screen. Also, make sure the center speaker does not cross the line formed by the leading edge of the front left and right speakers.

•

It is best to angle the speakers towards the listening position. The angle depends on the size of the room. Use less of an angle for bigger rooms.

•

Surround speakers should be positioned 60 cm to 90 cm higher than your ears and titled slight downward. Make sure the speakers don’t face each other. For DVD-Audio, the speakers should be more directly behind the listener than for home theater playback.

•

Try not to place the surround speakers farther away from the listening position than the front and center speakers. Doing so can weaken the surround sound effect.

•

Make sure that all speakers are securely installed. This not only improves sound quality, but also reduces the risk of damage or injury resulting from speakers being knocked over or falling in the event of external shocks such as earthquakes.

Connecting your equipment

Connecting the speakers

The receiver will work with just two stereo speakers (the front speakers in the diagram) but using at least three speakers is recommended, and a complete setup is best for surround sound.

Make sure you connect the speaker on the right to the right (R) terminal and the speaker on the left to the left (L) terminal. Also make sure the positive and negative (+/–) terminals on the receiver match those on the speakers. You can use speakers with a nominal impedance between 6  and 16 .

Be sure to complete all connections before connecting this unit to the AC power source.

Bare wire connections

Twist exposed wire strands together.

Push open the tabs and insert exposed

wire.

Release the tabs.

•

These speaker terminals carry HAZARDOUS LIVE voltage. To prevent the risk of electric shock when connecting or disconnecting the speaker cables, disconnect the power cord before touching any uninsulated parts.

•

Make sure that all the bare speaker wire is twisted together and inserted fully into the speaker terminal. If any of the bare speaker wire touches the back panel it may cause the power to cut off as a safety measure.
