To mount the Whistler 1640, use the suction cup bracket included in the package. Attach the bracket to the windshield, ensuring it is positioned so the detector has a clear, unobstructed view of the road. Adjust the angle as needed for optimal detection.
The Whistler 1640 can be powered using the included power cord that plugs into your vehicle's 12V outlet. Ensure the connection is secure and the cord is not obstructing any controls or vents.
To test the radar detector, drive past a known police radar site or use a radar gun if available. The detector should alert you when it detects radar signals. Ensure volume and sensitivity settings are appropriately configured.
Ensure the power cord is securely connected and check the fuse in the power cord plug. If the fuse is blown, replace it with a 2-amp fuse. Also, check your vehicle’s outlet to ensure it is providing power.
Press the "SEN" button to cycle through sensitivity modes: Highway, City, and City 1. Highway mode provides maximum sensitivity, while City modes reduce sensitivity to minimize false alerts in urban areas.
Regularly clean the detector's lens with a soft, lint-free cloth to ensure optimal performance. Check the mounting bracket and power cord for wear and tear, replacing them if necessary.
Yes, the Whistler 1640 is capable of detecting laser signals. Ensure the detector is positioned properly for an unobstructed view to maximize laser detection capability.
The Whistler 1640 is not designed for firmware updates. It operates with pre-installed firmware optimized for current radar and laser detection.
False alerts can occur due to non-police radar sources like automatic doors. Try switching to a City sensitivity mode to reduce false alerts, and ensure the detector is properly mounted.
The Whistler 1640 is pre-calibrated and does not require user calibration. Regular maintenance, such as cleaning the lens, will help maintain its accuracy.
