To install the Whistler XTR105, mount the device on your windshield using the provided suction cup mount. Ensure it is placed in a location with a clear view of the road. Connect the power cable to your vehicle's cigarette lighter or power outlet. Adjust the angle for optimal detection.
If your radar detector gives frequent false alerts, try adjusting the sensitivity settings. Switch to city mode to reduce sensitivity in urban areas, and ensure the detector is not obstructed by metallic objects or tinted windows.
To test your radar detector, drive past known speed enforcement areas or use a radar gun if available. The detector should alert you as you approach the radar source. Ensure the volume is turned up and the device is powered on.
To clean your Whistler XTR105, use a soft, dry cloth to wipe the exterior. Avoid using harsh chemicals or moisture. Regularly check the suction mount for stability and reposition if necessary. Inspect the power cable for any wear or damage.
If your radar detector is not turning on, check the power connection and ensure the cigarette lighter or power outlet is functional. Inspect the power cable for any damage. If the issue persists, try using a different power source or consult the user manual.
While radar detectors are legal in most states for passenger vehicles, they are prohibited in Virginia and Washington D.C. Additionally, they are illegal in commercial vehicles over 10,000 pounds. Always check local laws before use.
The Whistler XTR105 does not support firmware updates as it is a basic model. Ensure you have the latest version at purchase, and consult Whistler support for any device-specific inquiries.
Different alert tones indicate various radar bands detected by the device. For example, X, K, and Ka bands have distinct sounds. Refer to the user manual for a detailed explanation of each tone and its corresponding frequency band.
To reduce false alerts in city driving, switch your radar detector to city mode. This setting decreases sensitivity to prevent alerts from non-police radar sources, such as automatic door openers and other electronic devices.
The Whistler XTR105 can detect radar signals from several miles away, depending on the terrain, weather conditions, and signal strength. Its range is generally sufficient for most highway and urban environments.
