Ultrasonic cleaners designed to clean personal belongings (watches, glasses, toothbrushes, jewelery, etc.) at home.
The most important thing to consider when using it is that the digitally adjusted time is the maximum usage time.
Since these types of devices are closed devices, they do not have any natural air flow or fan cooling feature while operating.
At the end of the maximum period of use, it is necessary to let the device cool down to return to its initial operating temperature.
If the operating setting time is exceeded by repeatedly running, it is inevitable that you will encounter crystal breakage or card failure due to overheating.
This situation is not guaranteed. Because exceeding the ideal usage time limits is a mistake of the user.
In this case, the device repair is made against a fee.
