These levels determine the types of signals and signal ranges (bands) detected. Highway mode is the most sensitive level while City mode is the least sensitive. In Advanced mode, you can set the detection sensitivity level in 20% decrements from 100% to 40%.) Adjusting the sensitivity level does not shorten the range that the radar detector will detect signals. It limits the bandwidth strength that the radar detector will recognize. In other words, weaker signals will not be detected. MODE SENSITIVITY LEVELS Highway 100% (Full Sensitivity) City Ka same as Highway X and K: Reduced Advanced User-defined sensitivity levels in 20% decrements. • 100% = Full sensitivity • 80% = 3.5db attenuation • 60% = 7db attenuation • 40% = 10.5db attenuation If the X band is left on in City mode, a radar detector can pick up many X band signals (such as garage door openers) that generate false alerts. The DFR8 reduces X band sensitivity in City mode. When you are on the highway, there is less chance of picking up X band false alerts, so the DFR8 keeps the X band sensitivity on in Highway mode. - 14 -
