OPERATION
City Mode (Continued)
In City Mode, weak speed/safety radar
signals give an initial alarm of two beeps,
and then the unit remains quiet unless the
signal becomes very strong. When the signal
strength increases, two additional beeps are
provided. In City 1 Mode, only the X band
sensitivity is lowered. In City 2 Mode, X-band
is not detected.

Some towns/small cities may still
be using X band radar. City Modes do not
change the audio alert for laser or VG-2.
Highway Mode
Highway mode provides full audio warnings any
time radar (X, K, Ka, Safety Radar) or laser
signals are detected, and is recommended for
open road driving.
Dim/Dark Mode (1734 Only)
Dim/Dark Mode reduces the illumination of the
display.
• Press and hold Power for 2 seconds to
reduce illumination to a Dim setting.
• Pressing and holding the power button for 2
seconds a second time engages Dark Mode.
The display illumination is further reduced.
Dim or dark can be engaged during an
alert. In Dark Mode, the display goes dark
for as long as a signal is being detected
and for 20 seconds
after
, then the display
returns to the dimmer setting.
• Pressing and holding the power button a
third time restores full illumination to the display.
Engaging/Disengaging VG-2
See VG-2 detection mode to turn this feature on.
Vehicle Battery Saver Mode
The Vehicle Battery Saver Mode automatically
shuts off your detector after 6 hours if you
forget to turn it off. The timer is reset if the
detector is turned off, unplugged or any
button is pressed before the time has expired.
The detector will alert you with an audible and
visual warning before it shuts off.During this
warning you can momentarily reset the unit by
pressing any button. This will reset the timer. If
the unit has automatically turned itself off,
press any button to turn the unit back on.
Stay Alert Feature (1734 Only)
The Stay Alert Feature is designed to test a
driver’s alertness. To engage (when unit is not
alarming):
• Press and hold City for less then 2 seconds. The ”H” or
“C” will flash indicating Stay Alert is activated.Within
30-60 seconds two beeps are sounded; to show
alertness, the driver must press either the Volume, City
or Quiet button within 3-5 seconds. If the button is
pressed within 3-5 seconds, the cycle is repeated. If a
button was not pressed within 3-5 seconds, alarm
sounds and the display will flash all LEDs.
• Press Power to cancel Stay Alert.
WARNING!!! Stay Alert is NOT intended as a
substitute for adequate rest. You should NOT operate a
vehicle if you are drowsy. During extended periods of
vehicle operation, you should take frequent breaks.
Improper reliance on the Stay Alert may result in vehicle
damage, personal injury or death.
NEVER OPERATE A VEHICLE IF YOU ARE DROWSY.
OPERATION
Laser Audio / Visual Alerts
When a laser signal is detected, the display
indicates a laser by scrolling the alert LED’s
from right to left or displaying an “L” on the
display. The audio alert is continuous for a
minimum of 3 seconds.
Laser Tips
If you are the targeted vehicle, a laser gun
can often determine your speed within a few
seconds after you receive an alert. In this
situation there is generally no time to safely
adjust your speed. However, if you are
traveling near or behind the targeted
vehicle and receive an alert, response time
should be sufficient. Any laser alert, regardless
of duration, requires immediate action!
Pulse Protection
®
Pulse (or instant-on) radar is more difficult to
detect than conventional radar because it
remains “off” until activated to measure the
speed of a targeted vehicle. When a pulse
type transmission is detected, your Whistler
detector sounds an urgent 3-second audio
warning and flashes the Alert strength
indicators at their fastest rate. (The 1734
model displays “P”.) After the 3-second
pulse alert, the standard alert pattern contin-
ues for as long as the signal is present. It is
important to respond promptly to a pulse
alert, since warning time may be minimal.
