Notes on speaker use
- You can damage your speakers and shorten their useful life if you play
sound at high levels over extended periods.
- Reduce the volume in the following cases to avoid damage.
- When playing distorted sound.
- When the speakers emit strange noise (howling) from a / microphone or
record player, noise from FM broadcasts, or continuous signals from
an oscillator, test disc, or electronic instrument.
- When adjusting the sound quality.
- When turning the unit on or off.
Positioning for best effect
1. You cannot take the front net off the speakers.
2. Set the speakers up on an even surface to prevent them from falling.
Take proper precautions to prevent the speakers from falling if you
cannot set them up on an even surface.
3. Placing speakers too close to floor, walls, and corners can result in
excessive bass.

4. Cover walls and windows with a thick curtain.
5. Keep your speakers at least 10 mm away from the system for proper
ventilation.
6. Place the subwoofer on the floor or a strudy shelf so that it would not
cause vibration. Leave 10 cm at the rear for ventilation.
If irregular coloring occurs on your television
These speakers are designed to be used close to a television, but the picture may be affected with
some televisions and set-up combinations.
If this occurs, turn the television off for about 30 minutes
The television’s demagnetizing function should correct the problem. If it persists, move the speakers
further away from the television.
