What to do if my Uniden Radar Detector has signal but no audio?
If your Uniden Radar Detector's signal strength meter registers but there's no audio, ensure City Mode is OFF for highway use and increase the volume.
How to fix a Uniden Radar Detector that won't turn on?
If your Uniden Radar Detector is not operating and the power LED is off, check the power cord and ensure the connectors are properly installed. Make sure the ignition key is ON or in the accessory position. Check and replace the fuse if necessary. Also, verify power to the lighter socket, ensure the volume control is ON, and clean the cigarette lighter socket. If a vehicle electrical problem exists, it needs to be addressed.
Why does my Uniden LRD747 beep at the same location?
If your Uniden Radar Detector is beeping at the same location, it's likely falsing due to passing a motion sensor or alarm.
Why does my Uniden Radar Detector beep on bumpy roads?
If your Uniden Radar Detector beeps over bumps or rough roads, check that the power cord is securely connected at both ends and clean the cigarette lighter socket.
Why is my Uniden LRD747 Radar Detector not detecting signals well?
If your Uniden Radar Detector demonstrates weak detection, check the unit's angle, ensuring it points to the horizon. Move the unit clear of any obstructions outside the windshield, such as a wiper blade, and also ensure it is clear of any window tint.
