radio or television reception (which you can determine by unplugging the unit), try to correct the interference by one or more of the following measures:

•Re-orient the receiving antenna (that is, the antenna for the radio or television that is "receiving" the interference).

•Move the unit away from the equipment that is receiving interference.

•Plug the unit into a different wall outlet so that the unit and the equipment receiving interference are on different branch circuits.

For Your Safety

The AC power plug is polarized (one blade is wider than the other) and only fits into AC power outlets one

way. If the plug won’t go into the outlet completely, turn the

plug over and try to insert it the other way. If it still won’t fit, contact a qualified electrician to change the outlet, or use a different one. Do not attempt to bypass this safety feature.

Headset Safety

• Do not play your headset at a high volume.
	Hearing experts warn against extended
	high-volume play.
•	If you experience a ringing in your ears,
	reduce volume or discontinue use.
• You should use extreme caution or
	temporarily discontinue use in potentially
	hazardous situations.
•	Even if your headset is an open-air type
	designed to let you hear outside sounds,
	don’t turn up the volume so high that you
	are unable to hear what is around you.

Connecting to Audio Components

Connecting the Speakers

Speaker wires are color-coded to match the terminals. Connect the speaker wire from the back of each speaker to the corresponding color terminal at the back of the unit. Press down the tab to open the terminal and insert the wire. Release the tab to lock wire in

the terminal.

When connecting the speakers, make sure the polarities (“+” speaker wire to “+” on the unit. For example, red wire to red terminal on the unit) of speaker wires and terminals match.

If the cords are reversed, the sound will be distorted. Do not let the speaker wires touch each other, it will damage

the speaker.

When connecting subwoofer, connect subwoofer control cable (red/black striped) at the back of the subwoofer to the subwoofer control jack on the unit’s rear panel, then press POWER ON/OFF on the subwoofer speaker to turn it on.

• Do not install near any heat sources such as

radiators,heat registers, stoves, or other

apparatus (including amplifiers) that

produce heat.

• Do not defeat the safety purpose of the

polarized or grounding-type plug. A

polarized plug has two blades with one

wider than the other. A grounding type plug

Protect your Components from Overheating

•Do not block ventilation holes in any component. Arrange the components so that air can circulate freely.

•Do not stack components directly on top of each other.

•Do not place the unit near other components that generate heat such as heating vents.

•Allow adequate ventilation when placing your components in a stand.

•Place an amplifier near the top shelf of the stand so heated air rising from it will not affect other components. If you have a satellite receiver, you should place it on the top shelf.

Connecting the Antennas

Connect the AM and FM antennas to the AM and FM terminals on the system’s back panel.

They must be hooked up in order to receive clear reception. For FM reception, extend antenna to its full length. For AM reception, rotate the antenna horizontally to get better reception.

AM Loop Antenna and FM Indoor Antenna

1. Uncoil the antenna wire and locate the base

end of the AM antenna.

2. Press down on the antenna tab to open

the terminal.

3. Insert the antenna wires into the terminal

and release the tabs to secure the wires

in place.

4. Make sure the white wire on the AM loop

2. Center

In surround mode, the center speaker carries most of the dialog as well as music and effects. It should be set between the left and

right speakers.

3. Surround (Rear Speakers)

The rear speakers’ overall sound balance should be as close as possible to the front speakers. Proper placement is vital to establish an evenly distributed sound field.

Subwoofer

A subwoofer is designed to reproduce powerful low bass effects (explosions, the rumble of spaceships, etc.) which dramatically heighten the action on the screen.

Magnetic Shielding

Speakers placed less than two feet from the TV set must be magnetically shielded in order to prevent picture distortion. Front speakers provided with this unit are magnetically shielded to protect your TV set.

Note: Place the rear speakers and

Angle

Place the left and right speakers to form a 45- degree angle with your favorite viewing position to duplicate the soundtrack mixer’s perspective.

Height

The mid- and high-frequency drivers of the three front speakers should be as close as possible to the same height. This often requires placing the center speaker directly on top (A) or beneath (B) the TV set.
