Whistler XTR658 Laser Owners Manual

To install the Whistler XTR658, mount the detector on the windshield using the suction cup mount provided. Ensure it is positioned centrally for optimal radar detection. Plug the power cord into the detector and your vehicle's cigarette lighter or power outlet. Adjust the angle for a clear view of the road.
Check the power connection to ensure it is secure. Inspect the fuse in the power cord and replace it if necessary. Verify that the vehicle's power outlet is functioning properly. If the issue persists, consult the user manual or contact customer support.
To reduce false alerts, use the City mode to filter out non-threatening signals in urban areas. Adjust the sensitivity settings and enable features like VG-2 detection to block interference from other devices. Regularly update the device's firmware for improved performance.
Use a soft, dry cloth to clean the exterior of the detector. Avoid using harsh chemicals or abrasive materials that could damage the device. Regularly check the suction cups for dirt and clean them to maintain a secure mount. Store the detector in a cool, dry place when not in use.
Visit the Whistler Group website to download the latest firmware update. Connect your radar detector to a computer using the appropriate cable. Follow the on-screen instructions to complete the update process. Ensure the device has sufficient power during the update.
Highway mode provides maximum sensitivity for long-range detection. City mode reduces sensitivity to minimize false alerts in urban areas. City 1 and City 2 modes further decrease sensitivity for heavily populated regions. Choose the mode based on your driving environment.
Radar detectors can pick up signals from non-police sources such as automatic door openers or other electronic devices. Adjusting the sensitivity settings and using the appropriate mode can help reduce these false alerts.
Yes, you can hardwire your radar detector using a hardwire kit, which connects the detector directly to your vehicle's electrical system. This allows for a cleaner installation and frees up the power outlet. Follow the kit instructions for proper installation.
Continuous beeping can occur in areas with high electronic interference or where there are many sources of radar signals. Switching to a lower sensitivity mode or City mode can help minimize these alerts.
To test the functionality, drive past a known radar source such as a speed sign or police radar. The detector should alert you as you approach the source. Ensure that the device is configured correctly with appropriate sensitivity settings.
