Output sound pressure level: 101dB / mW. Play frequency band: 5 40000Hz. Please do the cancellation order when the address correction is necessary. Most of my products follow the Japanese electrical standard. All Japanese electric machineries operate at 95V-105 V (50Hz-60 Hz).Therefore, please do not use this product at a voltage over 105V! Since the United States uses voltages of 110V-120V, it cannot be used in the US. It also cannot be used at 220V-240V. One way to deal with this problem is to use a step-down transformer. There are important points in using a step-down transformer. If a machine you are using a transformer with has motor or generates heat, you will need a transformer with three times the wattage of the machine. For example, if the product operates at 100W, you will need a transformer with a capacity of 300W. This is because the machine needs two to three times the amount of electric power than normal to start up.
Please be aware that deficiencies in capacity can lead to breakdown of the transformer or the product, and, in the worst case, can cause a fire. The plug type in Japan is type A. Plug types also differ across countries, so please use a conversion adapter to change the plug to type A if plug types are different.Conversion adapters also have electric power limits, so please use them accordingly. There are some conversion adapters that are originally designed to handle 100V-240V, so you can check the instructions on them about electrical outputs. If a conversion adapter can handle the electric power, all you need to do to use the product in your country is to change the plug to type A. In addition, most issues that result in being unable to turn on the product is due to the breaking down from using the incorrect transformer. If you insist on exchanging or returning the product, I will send the product to the factory for inside inspection. Caution: I will not be held responsible for any accident caused by using a wrong step-down transformer.
