cty (City X/Highway) Button The cty X mode has been designed to effectively reduce unwanted audio alerts caused by intrusion alarms, door openers, and other devices which share X band with police Radar-without reducing sensitivity. Signals from non-police Radar sources are frequently encountered in urban and suburban areas, making use of this mode ideal in these areas. Pressing the cty button once engages the cty X mode which is confirmed by "CITY" in the display coupled with a single audio "beep". Pressing the cty twice returns you to highway mode; "HIGHWAY" will appear in the display coupled with two"beeps". Once cty X mode is engaged, weak X band signals encountered will produce no audible alert until the signal strength reaches a preset level. However, visual alerts are processed the instant an X band signal is detected, keeping you quietly informed. Since most "false" X band signals are weak, the use of the cty mode allows you to drive out of their range before they reach the preset level and trigger a full audio alert. In contrast, signals from X band traffic Radar are generally stronger and will exceed the preset level, causing a full X band audio alert. Activating the cty mode will not change Super Wideband Ka, K or instant-on X band Radar alert patterns. Note-the cty mode does not change the presentation of alerts for Laser sws™ or - signals. City ALL (X/K/Ka) City ALL provides an alternated approach for improving X, K and Ka band selectivity and is ideal for use in areas with a high level of microwave transmissions which can cause falsing on all three bands. To engage City ALL mode, press cty until the Display shows "CITY ALL". Once engaged, weak X, K or Super Wideband Ka signals encountered will provide no audible alerts until the signal strength reaches a preset level. Visual alerts are processed the instant an X, K or Super Wideband Ka signal is detected, keeping you quietly informed. 
