Precautions

The supplied AC adaptor is designed exclusively for this unit. It should not be used in combination with any other devices.
Completely disconnect the AC adaptor from the AC outlet (mains) if it is not going to be used for an extended period of time. When unplugging the AC adaptor, be sure to grasp it by its adaptor section, not by its cord.
Do not remove the plug part from the AC adaptor and connect the plug to the AC outlet (mains) alone. There may be a risk of electric shock or fire.
When using a commercially available AC adaptor, use a USB PD compatible AC adaptor with a rating of 15 W or higher. Note charging may take time and that the original performance may not be obtained.
– If you use an AC adaptor other than the above, the charging indicator on the front speaker may blink and the unit may not be charged.
– When using a commercially available USB PD compatible AC adaptor, use a USB PD compatible USB Type-C® cable (USB standard compliant product).

On placement

When carrying the rear speakers on the front speaker, hold the front speaker firmly, not the rear speakers, to prevent them from slipping out of your hands.
Do not splash water onto this product and the supplied accessories. Those are not waterproof.
To eliminate the risk of malfunctions, avoid the following locations when placing or leaving this unit.
– 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 unit on a flat, level surface. When placed on a sloped surface, the unit 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 unit is placed, it may fall over or fall off the surface. Do not leave any valuables near the unit.
This unit is not anti-magnetic. Keep objects susceptible to magnetism (recorded tapes, watches, cash cards and credit cards with magnetic coding, etc.) away from the unit. When you carry around the unit, keep this in mind as well.
Do not place metal objects other than a TV around the unit. Wireless functions may be unstable.
If you use this unit for a long time, the temperature of this unit may rise, but it is not a malfunction.
At high temperature, the charging may stop or the volume may reduce to protect the battery.
Do not use or leave the unit in an extremely cold or hot environment (temperature outside the range of 5 °C – 35 °C (41 °F – 95 °F)). If the unit is used or left in outside the above range, the unit may automatically stop to protect internal circuitry.
Even if you do not intend to use the unit for a long time, charge the battery to its full capacity once every 6 months to maintain its performance.
