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 sub-
urban 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 VG -2 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.
