【Cautions for using electrical products】 When using electrical appliances, please note that the voltage is different from that of Japan, which may cause malfunctions. Since the plug type is Japan type(A or B type), please check the voltage and use a transformer. Please note that a transformer is different from a conversion adapter. We are not responsible for malfunctions caused by use without a transformer. Easy 4-step measurement: ① Slide the sensor cover. ② Turn on the power. ③Blow into your mouth for about 4 to 5 seconds. ④Measurement is complete. The measurement results are displayed as numerical values and notifications in three levels: ``Safety, Warning, and Danger.'' *Please refer to the instruction manual for details and precautions. Adopts a high-precision semiconductor gas sensor: Adopts a high-quality, highly sensitive semiconductor gas sensor with high reliability and quick response. Detects alcohol quickly. By heating the sensor with a heater, dirt and impurities adhering to the sensor are removed and the sensor's reaction is accelerated, allowing highly accurate measurements. Rechargeable and does not require batteries: Since it is rechargeable, there is no need to replace batteries. You can use it repeatedly by charging it with the included USB Type-C cable. Save 99 measurement results: Up to 99 measurement records can be saved on the main unit. If you miss a measurement result, you can check the results from past measurements. *Measurement records are recorded in order from 01 to 99. When 99 results are reached, the measurement results starting from 01 will be overwritten. Equipped with measurement error detection function: In order to perform more accurate measurements, this function displays Err to notify you if you do not blow or if you do not blow sufficiently. *Accuracy may vary depending on usage conditions, individual constitution, physical condition, etc. 1 year warranty for peace of mind: This product comes with a 1 year warranty. In the unlikely event that a problem occurs during use, we will repair or replace it free of charge. In order to ensure that our customers can use our products with peace of mind, we place emphasis not only on quality but also on our support system. *However, this is limited to products that have been measured less than 1500 times.
