To install the Whistler Z31R Plus, mount the detector on the windshield using the provided suction cups and bracket. Ensure it is positioned low enough for a clear view of the road but high enough to avoid obstruction. Connect the power cord to the detector and plug it into the vehicle's cigarette lighter socket.
If the detector is not powering on, check the power connection to ensure the cord is securely plugged into both the device and the power source. Test the cigarette lighter socket with another device to confirm it is working. If the issue persists, inspect the fuse in the power cord for damage and replace if necessary.
To reduce false alerts, ensure the detector is mounted correctly. Use the City mode to minimize alerts from non-police radar sources in urban areas. Regularly update the detector’s firmware to improve filtering capabilities.
Regularly clean the lenses with a soft, lint-free cloth to maintain detection performance. Check for firmware updates periodically and install them to ensure optimal functionality. Store the detector in a cool, dry place when not in use to prevent damage.
To update the firmware, visit the Whistler Group’s official website and download the latest firmware version for the Z31R Plus. Follow the included instructions to connect the device to a computer via USB and complete the update process.
Continuous beeping may be caused by interference from other electronic devices or a faulty power connection. Ensure the detector is away from other electronic devices and check the power cord and connection for any issues.
