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:
•
•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.

•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.

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.
