To install the Whistler XTR140, mount the unit on the windshield using the provided suction cups. Plug the power cord into the detector and then into the vehicle's 12V power outlet. Ensure it has a clear view of the road ahead for optimal performance.
To test the detector, drive in an area known for radar activity and observe if the unit alerts you as you approach radar sources. Additionally, you can use a radar gun or visit a location where radar speed signs are present.
Press the volume button on the unit to cycle through the available volume levels. Continue pressing until you reach the desired volume setting.
False alerts can occur due to automatic door openers or other electronics. Use the filter modes available in the detector to reduce false alerts and adjust the sensitivity settings accordingly.

Different alert tones correspond to different types of radar bands detected. The manual provides a detailed guide to the tones and their corresponding radar bands.
To clean the detector, use a soft, dry cloth to wipe the exterior. Avoid using any harsh chemicals or water. Regularly check the mounting to ensure it is securely attached.
If the detector does not power on, check the power connection and ensure the 12V outlet is functioning. Inspect the power cord for any damage. If the problem persists, consult the user manual or contact customer support.
