On safety

  • Completely disconnect the AC power cord (mains lead) from the AC outlet (mains) if it is not going to be used for an extended period of time. When unplugging the speaker, always grip the plug. Never pull the cord itself.

On placement

  • To eliminate the risk of malfunctions, avoid the following locations when placing or leaving this speaker.

    • A place subject to high temperatures, such as under direct sunlight or lighting equipment, near a heat source, or in a sauna

    • Inside a vehicle with the windows closed (especially in summertime)

    • A place subject to excessive dust

    • A place subject to strong vibration

  • Place this speaker on a flat, level surface. When placed on a sloped surface, the speaker may fall over or fall off the surface due to its own vibration, resulting in injuries, malfunctions, or performance degradation.

  • Depending on the conditions where this speaker is placed, it may fall over or fall off the surface. Do not leave any valuables near the speaker.

  • This speaker is not anti-magnetic. Keep objects susceptible to magnetism (recorded tapes, watches, cash cards and credit cards with magnetic coding, etc.) away from the speaker. When you carry around the speaker, keep this in mind as well.


  • If you use this speaker for a long time, the temperature of this speaker may rise, but it is not a malfunction.

  • Do not use or leave the speaker in an extremely cold or hot environment (temperature outside the range of 5 °C – 35 °C (41 °F – 95 °F)). If the speaker is used or left in outside the above range, the speaker may automatically stop to protect internal circuitry.

  • At high temperature, the charging may stop or the volume may reduce to protect the battery.

  • Even if you do not intend to use the speaker for a long time, charge the battery to its full capacity once every 6 months to maintain its performance.
