Whistler XTR135 Laser Owners Manual

To install the Whistler XTR135, mount the device on your windshield using the provided suction cups. Make sure it's positioned high enough for a clear view of the road. Connect the power cord to your vehicle's 12V power outlet.
Ensure that the power cord is securely connected to both the device and the vehicle's power outlet. Check the fuse in the power cord if the problem persists.
Use the City mode to reduce false alerts in urban areas. Adjusting the sensitivity settings can also help minimize erroneous signals.
The 'VG-2' alert indicates that a VG-2 radar detector detector is nearby. The XTR135 is equipped with VG-2 cloaking technology to prevent detection.
The Whistler XTR135 does not support software updates, as it is a standalone device without upgradeable firmware.
Continuous beeping may indicate a strong radar signal or interference. Ensure the detector is correctly mounted and try moving it to a different location on your windshield.
The Whistler XTR135 typically has a range of up to several miles for radar detection, depending on terrain, weather conditions, and the type of radar being used.
To reset the device, turn it off, then press and hold the 'Power' and 'Quiet' buttons simultaneously until the display shows 'Reset'.
An 'Err' message may indicate a problem with the device's internal components. Try resetting the device or consult the user manual for further troubleshooting.
To clean your Whistler XTR135, use a soft, damp cloth to gently wipe the exterior. Avoid using any harsh chemicals or abrasive materials. Regularly check and clean the lens to ensure optimal performance.
