CompTIA A+ Core 1 (220-1101) — Question 405

A frequently used projector continuously shows a message to clean the air filters. The technician checks the filters, and they are dean. Which of the following preconfigured settings is causing the projector to show the message frequently?

Answer options

• A. Image calibration
• B. Hours of use
• C. Temperature
• D. Image source

Correct answer: B

Explanation

The 'Hours of use' setting is likely configured to alert the user after a certain number of operating hours, indicating that maintenance is needed, even if the filters are clean. The other options, such as Image calibration, Temperature, and Image source, do not directly relate to the maintenance notifications and would not trigger the cleaning message.
