I have a problem with my new uscutter MH 871 that I recently bought. The problem could be summarized as follow:
1. There is a big loud sound once the power switch is turned on.
2. Once the test button is pressed the cutter produce some strange drawing. I am attached sample.
3.At the pressing of setup button on the control panel, the machine produce big and load sound.
I am looking for your help as I have tried many ways but without success.
