What must a client do to start the Skin Wellness Pro machine?

To initiate the Skin Wellness Pro machine, the client must press the START button. This action is a fundamental step in operating the machine, as it triggers the system to begin its pre-programmed functions and treatments.

Pressing the START button is crucial because it not only signifies the client's readiness but also ensures that the machine is set to proceed with the specified procedures. Without this action, the machine remains inactive, regardless of any other settings that may be adjusted beforehand.

It's common for equipment to require a specific action to be taken to move from a standby state to active operation, making the START button an essential part of the operational process.
