International safety notice

An alarm is issued when one of the two processors that monitors each other goes into forced shutdown during ventilation operation. An exceptional event in which ventilation stopped without any warning was discovered during an in-house bench test at an overseas manufacturer, and a firmware countermeasure was developed. Since April 12, 2022, we have carried out a recall for upgrading to We have issued a new warning and confirmed several cases where ventilation stopped. Investigation revealed that this issue was a combination of hardware and firmware issues, and primarily occurred when charging the removable battery. I found out what you're doing. It turns out that there are times when the ventilation stops, resulting in a forced shutdown. Due to a shortage of supply of signal buffers on circuit boards, substitute parts were temporarily adopted, but the substitute parts had noise It has also been confirmed that failures caused by these parts occur at a higher rate than with genuine parts. To address this issue, firmware upgrades are available to minimize the effects of noise interference on the communication bus. do the following.
