Notes on use To protect the speakers from damage caused by excessive input, observe the following precautions: ≥ Do not apply inputs exceeding the permissible range. ≥ Avoid raising the volume level too much when enhancing the treble sound with a graphic equalizer. ≥ Avoid outputting excessively loud sound with a small power amplifier. Doing so will increase the amplifer's harmonic distortion and may damage the speakers. Protection circuitry These units incorporate protection circuitry to protect them from damage caused by excessive input or abnormal signals; when excess input is detected, input is automatically interrupted. ≥ If sound is interrupted... 1. Reduce the volume of the receiver (or amplifier). 2. Check the sound source and connections for any problems. If there is no problem, the protection circuitry will reset in a few minutes. ≥ After the protection circuit is reset... Take care not to increase the receiver's volume too high. Unit care Clean the speakers with a soft, dry 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. 10

Notes on use
To protect the speakers from damage caused by excessive input, observe the following precautions:
≥
Do not apply inputs exceeding the permissible range.
≥
Avoid raising the volume level too much when enhancing the treble sound with a graphic equalizer.
≥
Avoid outputting excessively loud sound with a small power amplifier. Doing so will increase the amplifer’s harmonic distortion
and may damage the speakers.
Protection circuitry
These units incorporate protection circuitry to protect them from damage caused by excessive input or abnormal signals; when
excess input is detected, input is automatically interrupted.
≥
If sound is interrupted...
1.
Reduce the volume of the receiver (or amplifier).
2.
Check the sound source and connections for any problems.
If there is no problem, the protection circuitry will reset in a few minutes.
≥
After the protection circuit is reset...
Take care not to increase the receiver’s volume too high.
Unit care
Clean the speakers with a soft, dry 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.
