OPERATION
City/City 1/City 2 Modes
Whistler’s City Modes are designed to reduce the annoyance
of automatic door openers, intrusion alarms and other devices
which share frequencies with police radar. Generally, X band is
used for these devices.
• Press City to cancel Highway Mode and engage City Mode.
• Press City again to enter City 1 Mode.
• Press City again to enter City 2 Mode.
• Press City a fourth time to cancel City 2 Mode and returns the
unit to Highway Mode.
In City Mode, weak speed/safety radar signals give an initial alarm
of two beeps, and then remain quiet until the signal becomes very
strong. When the signal strength increases, two additional beeps
are provided. City 1 and City 2 Modes operate the same as Highway
Mode, but in City 1 Mode, only the X band is lowered. In City 2
Mode, X-band is not detected.
CAUTION: Some towns/small cities may still be using X band
radar. City Modes do not change the audio alert for laser.

OPERATION
Highway Mode
Highway mode provides full audio warnings any time radar (X,
K, Ka, and Safety Radar) or laser signals are detected, and is
recommended for open road driving. For more information on
City and Highway modes, please visit our FAQ page on our
website: www.whistlergroup.com
Selectable Signal Strength Display
There are two settings available in Option Mode that effect how
a received radar signal strength is displayed. The “RMP STD”
(ramp standard) option uses our standard signal progression
from level 1 to 9. The “RMP FST” (ramp fast) option increases the
progression from level 1 to 9. RMP FST increases the response of
the signal strength meter for all bands.
1 = weak signal, 9 = strong signal

14
OPERATION
Horizontal/Vertical Viewing
The display can be mounted in 3 different ways:
• Horizontally
• Upside Down
• Vertically
Refer to "Option Select Mode" to change display viewing.

15
OPERATION
Vehicle Battery Saver Mode
Vehicle Battery Saver Mode automatically shuts off the
detector if the unit has constant power.
The timer is reset:
1. Each time the detector is turned off.
2. The power cord is disconnected or power is removed to the
unit.
3. Any button is pressed before the timer has expired. The
detector will alert you with an audible and visual warning
before it shuts off. This auto off function can be programmed
for the following: Off, 1, 3, or 6 hours. During this warning
you can reset the timer by pressing any button. If the unit has
automatically turned itself off, press the Power button to turn
the unit back on.
Field Disturbance Sensor Rejection (FDSR)
Traffic Flow Sensor Rejection (TFSR)
Recently many new products that operate on police radar
frequencies have been causing nuisance alerts to radar detectors.
These radar based sensors are installed alongside the Highway
and more recently on vehicles used as lane change assist / blind
spot detectors / collision avoidance systems. TFSR when turned
ON is designed to eliminate alerts from specific Traffic Flow
sensors. FDSR when turned ON is designed to identify all radar
based collision avoidance systems that operate within the same
band as police radar and provide a brief less intrusive alert
to keep you informed and aware. A signal strength indicator
will help determine your proximity to the source without the
continued annoyance of audio.
We suggest you turn FDSR ON if you are experiencing
excessive random false alerts when behind select vehicles.

16
OPERATION
Security Mode
When the unit is powered off by the Vehicle Battery Saver
Mode or by pressing the power button, the Security LED will
begin to flash if the security LED option is turned on. This
simulates a vehicle alarm system.
X/K and Ka Filter Modes
There are times when a radar detector in another vehicle, can
emit a frequency which can cause your detector to falsely alert.
These Filter Modes allow you to select the level needed for your
area to minimize the occurrences of these false alerts. X/K and
Ka Filter Mode factory default settings should provide adequate
filtering for most conditions. If you experience excessive alerts
due to radar detectors in other vehicles, increase the Filter level
for the band received. See Option Selection Mode to change the
filter settings.
NOTE: Speed selectable Filter is available with the optional GPS
module.
Ka Max Mode
Ka Max Mode provides enhanced Ka sensitivity - increased
detection. This mode can be selected with or without RSID. See
Option Select Mode for changing Ka options.
VG-2 Detection Mode
See Option Select Mode to turn this feature on/off. When a VG-2
signal is detected, the VG-2 alert is sounded and the display
flashes “VG-2”. After 3 seconds the audio is canceled and the
display no longer flashes. This cycle is repeated if the VG-2 signal
is detected again.
During the period a VG-2 signal is detected, a radar signal
cannot be detected.
However, because the VG-2 alert has confirmed that a patrol
car is nearby, you are already aware of the potential for speed
monitoring and can adjust your speed accordingly. Laser
detection is not affected while a VG-2 signal is detected.

17
OPERATION
Radar Signature ID (RSID) with Voice Prompts
Identify the difference between the likelihood of a Ka threat vs.
the likelihood of a Ka false from another source (possible radar
detector).
The Ka RSID feature will educate you to the common Ka speed
radar guns by displaying and announcing the nominal police
radar frequencies of 33.8GHz / 34.0GHz / 34.3GHz / 34.7GHz /
35.5GHz. The Ka alerts that do not fall into the common Ka
speed radar windows will be reported only as Ka.
NOTE: This product is not a frequency counter. The unit will
categorize the received Ka signal and select the appropriate
information. Treat every Ka alert with caution.
Laser Signature ID (LSID)
Identify the Laser gun’s pulse rate or PPS (Pulses per Second)
that is transmitted by the speed laser gun. LSID may also be
used to identify other forms of laser sources such as LACC
(Laser Assisted Cruise Control) systems found in some high end
vehicles. If the Laser PPS information displayed is due to
another source such as local airports or LACC, LSID allows you
to Lock Out this rate from giving you the continuous audio alert
during this and any new encounter of the same rate. To lock out
a PPS, press the Quiet button during the Laser alert. This will
place an * on the screen beside the PPS rate and Lock Out this
signature ID. Any new encounter with the same Laser Signature
ID will provide the display information and two quick beeps.
Note: Common Laser PPS rates used in the USA are 100 / 125
/ 130 / 200 / 238 / 380Hz. Currently other Laser PPS rates used
outside the USA include 600Hz.
CAUTION: Do not lock out a PPS rate if it is close to known
speed laser guns.

18
Adjustable Laser Receiver
If these alerts are bothersome, you may wish to turn on the
LSID feature and make note of the PPS rate for these
occurrences.
The laser validation windows are separated into 4 groupings
allowing for customization to eliminate and/or make less
frequent the number of laser alerts from these non police
sources such as airports, laser assisted cruise control systems
and more.
An example of this may be to shorten the first window from
.05-1.0 to .05-.90, the second window can be adjusted from
1.0-2.0 to 1.2-2.0. You now have ignored any laser that has
an average PPS rate between 900Hz and 1200Hz. Validation
will occur from 50Hz to 900Hz, and resume from 1200Hz to
2000Hz.
If laser within a group is not used in your country, you may shut
off that group (change the selection from Y to N while in Option
Select Mode) by pressing the PWR and DARK button at the same
time then releasing.
Red Light/Speed Camera Detection
The PRO3700 is capable of alerting to these locations with the
optional RLC-360 GPS module and an updatable database.
