LED SIGNAL STRENGTH METER IN CITY MODE The LED signal strength meter gives you instant information about the strength of the signal being detected. A weak signal causes the first LED to light, but as signal strength increases, more LEDs light. All three LEDs light when full signal strength is received. Use this meter to judge the distance from the signal source.

The LRD 747/LRD 757 is capable of detecting the SWS signal broadcast on the K-band by either law enforcement or local departments of transportation. The green SWS LED blinks while an audible alert sounds. When this alert sounds, you should tune to local radio traffic reports or prepare to slow down or stop your vehicle because you could be approaching an accident, bad road conditions caused by weather, or road crews or construction.
