CITY (City Highway) Button The CITY 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. CITY X Mode Pressing the CITY button once engages the CITY X mode which is confirmed by "CITY" in the display coupled with a single audio "beep". Pressing the CITY button twice returns you to highway mode; "HIGHWAY" will appear in the display coupled with two "beeps". Once CITY 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 CITY 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 CITY mode will not change Super Wideband Ka, K or instant-on X band Radar alert patterns. Note-the CITY mode does not change the presentation of alerts for Laser sws™ or VG-2 signals. City ALL (X/K/Ka) City ALL provides an alternative approach for improving selectivity on all three bands, 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 CITY until the Display shows "CITY ALL". Once engaged, weak X, K or Super Wideband 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. 8
