Notes on use
To protect the speakers from damage caused by excessive input, observe the following precautions:
≥
Reduce the volume in the following cases to avoid damage:
j
When playing distorted sound.
j When the speakers are receiving howling from a microphone or record player, noise from FM broadcasts, or continuous
signals from an oscillator, test disc, or electronic instrument.
j
When adjusting the sound quality.
j
When turning the amplifier on or off.
≥ Avoid raising the volume level too much when enhancing the treble sound with a graphic equalizer or any other controls.
≥ Avoid outputting excessively loud sound with a small power amplifier. Doing so will increase the amplifer’s harmonic distortion
and may damage the speakers.
≥
You can damage your speakers and shorten their useful life if you play sound at high levels over extended periods.
≥ Do not touch the speaker terminals with your hands or other objects while the speakers are in use. Depending on the conditions
of use, doing so may expose you to high voltage.
Unit care
Wipe the speakers with the supplied cleaning cloth.
≥ When dirt is heavy, wring a wet cloth tightly to wipe the dirt, and then wipe it with a dry cloth.
≥
Do not use solvents including benzine, thinner, alcohol, kitchen detergent, a chemical wiper, etc. This might cause the exterior
case to be deformed or the coating to come off.
