Which action is described as part of annual equipment upkeep?

• A. Inspect general cleanliness
• B. Recalibration
• C. Test alarm sounds
• D. Replace battery packs

Answer: (B)

Recalibration is central to annual upkeep because it directly maintains the device’s accuracy and safety. Over time, components can drift, causing output parameters like intensity, frequency, or duration to deviate from the manufacturer’s specifications. Scheduling a recalibration opportunity with a qualified technician restores alignment to a trusted reference, ensuring the equipment delivers consistent, expected therapeutic effects and remains compliant with standards.

Inspecting cleanliness is important for general hygiene and upkeep but is typically handled through routine cleaning or more frequent checks, not strictly tied to yearly calibration. Testing alarm sounds and replacing battery packs are common safety and maintenance tasks that occur on a more frequent basis or as-needed, rather than as a standard annual calibration activity.
