Show answer and explanation
Correct answers: B, C
Explanation
Wireless mouse issues like disconnections and delays are often caused by signal interference or low battery levels. Moving the USB receiver closer to the mouse can improve the connection, while replacing the low batteries ensures the mouse operates smoothly. These two actions directly address the reported problem without requiring unnecessary replacement or impractical adjustments.
- A. Incorrect.
Replacing the mouse with a wired model may resolve the issue but is not the most practical or cost-effective solution. The problem can likely be fixed without replacing the device.
- B. Correct.
Moving the USB receiver to a front USB port closer to the mouse can help improve the signal strength and reduce interference, making it a valid solution.
- C. Correct.
Replacing the mouse's batteries is essential, as low battery levels can cause intermittent disconnections and delays.
- D. Incorrect.
Adjusting the wireless channel of the mouse is not a standard feature for wireless mice, and most do not allow this adjustment.
- E. Incorrect.
Asking the user to reduce the number of nearby wireless devices may help slightly, but it is not a direct or practical solution in this scenario.
