For monthly maintenance, select the activity that addresses wear and tear on cables.

• A. Recalibration
• B. Update firmware
• C. Check power cords for fraying or wear
• D. Clean outer surface

Answer: (C)

Regular monthly maintenance prioritizes the physical health of the device, especially its power cables. Inspecting power cords for fraying, cracks in insulation, or damaged plugs targets the exact issue of wear and tear that can lead to electrical hazards or unexpected failures. Catching damaged cords early allows you to replace them before problems arise, keeping the equipment safe and reliable.

Recalibration serves to ensure accuracy of performance settings, not the condition of cables. Firmware updates involve software changes rather than the hardware’s insulation or integrity. Cleaning the outer surface addresses appearance and hygiene but does not protect against electrical faults from worn cables.
