CTY (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. Pressing the CTY button once engages the City X mode which is confirmed by a single "beep" and the illumination of the yellow city LED labeled H/C. Once 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 X mode will not change Super Wideband Ka, K or instant-on X band Radar alert patterns. Note-the city mode has no effect on the reception of Laser or SWS. City X/K/Ka City X/K/Ka provides an alternate 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 X/K/Ka mode, press the City button twice. City X/K/Ka is confirmed by the alternate flashing of the green/amber H/C LED for one second. After the one second, the LED returns to solid amber illumination. 8 Once engaged, weak X, K or Super Wideband Ka signals encountered will produce 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. Pressing CTY a third time returns you to highway mode; two beeps and the illumination of the green H/C LED confirms highway mode. Reset to Factory Settings You can reset your unit to factory settings for volume, DRK, AUDIO, CITY and Selectable Features. With the unit OFF press and hold the AUD and CTY buttons, then press the PWR button. Two "beeps" will confirm factory settings are reset. Your unit is now ON and ready for operation. Selectable Features Auto-Mute, Safety Warning System, X, K, Super Wideband Ka ON/OFF and the four Ka Narrow frequencies: 33.8 GHz, 34.3 GHz, 34.7 and GHz, 35.5 GHz, are all features that may be selected ON or OFF, depending upon your preference. Auto-Mute On/Off When activated, unit will provide several X, K, Super Wideband Ka audio alerts followed by a "clicking" tone to keep you quietly informed for as long as the signal is present. The clicking becomes more rapid as the strength of the Radar signal increases. Auto-Mute enables you to conveniently monitor extended encounters without having to manually mute or adjust the volume setting. Note-because of their urgency, Laser alerts are not affected. 9
