alarming):
• Press and hold the City button 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 City, Menu 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, the alarm sounds and the display
flashes all the LEDs.
• Press Dark 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 indi-
cates alert by illuminating the “V/L” and scrolling
the signal strength indicators from right to left or
display indicates 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 . Models XTR140/150 will flash the
Alert strength indicators at their fastest rate;
on models XTR-255/260/310/330 a “P
P” will be
displayed. After the 3-second pulse alert,
the standard alert pattern continues for as
long as the signal is present. It is important to
respond promptly to a pulse alert, since
warning time may be minimal.
