Before beginning a direct or indirect application, make sure the current is turned:

• A. Off
• B. On
• C. Standby
• D. Low

Answer: (A)

Safety in electrical device use requires that no current is delivered during setup and contact. Turning the current off eliminates energy in the circuit, preventing accidental shocks, burns, or unintended device activation as you position the client, attach accessories, or prepare the area. It also gives you a safe moment to inspect equipment and ensure everything is properly connected without live power. Standby or low settings can still carry energy or respond if a control is bumped, so they aren’t as reliable a safeguard as fully turning the device off. Once everything is ready, you can power the device back on and set the appropriate level for the treatment.
