1. If you notice any abnormality, please turn off the machine immediately. If you notice smoke, flames, unusual odors, or abnormal noises coming from the machine, please turn it off immediately and unplug the power cord.
2. Never open the back cover (main unit, instruments). There is a very high voltage inside. Opening the back cover may result in electric shock. Only qualified personnel should open the back cover.
3. Do not put any objects inside the machine. The main unit and instruments contain numerous integrated circuits. The through-holes in the instruments are for heat dissipation. If they are blocked, the instruments may be damaged due to the inability to dissipate heat properly. Inserting metal objects may damage the internal circuitry of the machine. Furthermore, blocking the through-holes with metal objects may also cause electric shock.
