Statement
 The product is designed compatible with the high-frequency surgical equipment, i.e. it is allowed to
keep working or standby near the high-frequency surgical equipment.
 In case of interrupted AC input voltage, the product will shut down, and once the power supply is
restored, it can be manually restored by the operator. The degradation in such case is acceptable
because it will neither cause unacceptable risks nor impair basic safety or essential performance.
 The degradation due to electrostatic discharge or electrical fast transient/burst is acceptable because
it will neither cause unacceptable risks nor impair basic safety or essential performance.
 The vertical-line flashing on the screen can automatically restore to the previous state.
