TURN-ON SEQUENCE
(FOR K40-1000/1000P MODELS)
When starting your vehicle, the unit will go
through a full audio and visual test.
1. The red alert light will illuminate.
2. The radar audio tones will be heard:
1st tone: “Tweet” = X-band
2nd tone: “Chirp” = K-band
3rd tone: “Buzz” = Ka-band
3. The red alert light will flash and the
pulse/instant-on “beep” will sound.
4. The red alert light will flash and the continu-
ous high pitched laser “beep” will sound (for
models that integrate the Defuser EX or EX2).
5. The red alert light will go out.
This power-up test indicates the radar detector is
functioning and ready to receive radar.
TURN-ON SEQUENCE
(FOR K40-2000/2000P MODELS)
When starting your vehicle, the unit will go
through a full audio and visual test.
1. Both the front and rear red alert lights will
illuminate.
2. The front radar audio tones will be heard:
1st tone: “Tweet” = X-band
2nd tone: “Chirp” = K-band
3rd tone: “Buzz” = Ka-band
3. The front red alert light will flash and the
pulse/instant-on “beep” will sound.
4. The rear audio will sound with a “Brap” tone.
5. The rear red alert light will flash and the
pulse/instant-on “beep” will sound.
6. Both front and rear red alert lights will flash
and the continuous high pitched laser “beep”
will sound (for models that integrate the
Defuser EX or EX2).
7. The front and rear red alert lights will go out.
This power-up test indicates the radar detector
is functioning and ready to receive radar.
CITY/HIGHWAY ADJUSTMENT
When the sensitivity switch is in the HIGHWAY
mode, your radar detector will provide full sensi-
tivity and warnings to all FCC allocated radar
bands and technology. Upon selecting this mode
the optional bi-color LED will glow GREEN.
When the sensitivity switch is in the CITY mode,
your radar detector will virtually eliminate false
alerts by removing all X-band radar signal warn-
ings, the most common source of non-police
radar signals. This mode also engages a filter
system that is designed to reduce other weaker
non-police signals while remaining on total top
alert for police radar. Upon selecting this mode
the optional bi-color LED will glow YELLOW.
RADAR ALERT TONES
X-band = “Tweet”
K-band = “Chirp”
Ka band = “Buzz”
*Rear Radar = “Brap”
*(K40-2000/2000P models only)
LASER ALERT TONE
When encountering a police laser signal models
equipped with the optional Laser Defuser EX or
EX2 will respond with a continuous high pitched
“beep,” accompanied by rapid flashing of the
alert LED light (both front and rear alert LEDs
flash on K40-2000/2000P models).
INSTANT-ON RADAR WARNINGS
When your radar detector detects an instant-on
or pulse radar signal, it sounds an urgent, high
pitched “beep,” accompanied by rapid flashing
of the appropriate alert LED light (front or rear).
After a series of “beeps” the alert tone will
switch to the appropriate X, K, or Ka band tone.
LINEAR GEIGER CIRCUIT
During a radar encounter audio and visual alerts
will intensify as you get closer to the police threat
and diminish as the threat passes.
MUTE CIRCUIT
Once radar is detected system audibly alerts for
several seconds and then automatically switches
to a quiet clicking to reduce distraction during
prolonged encounters.
ALERT OVERRIDE
DETECTION CIRCUIT
To ensure total protection against police speed
measuring guns, your K40 radar detector is
designed to prioritize incoming signals and alert
you to the most urgent threat based on the type
of signal detected. Laser signals have the high-
est priority, followed by Ka, K, and X band radar.
RADAR ALERT SEQUENCE FOR
FRONT & REAR MODELS
(FOR K40-2000/2000P MODELS)
As you approach a police radar signal your radar
detector will activate the front alert LED light and
sound the appropriate radar warning tone for X,
K, or Ka band. As you enter the immediate prox-
imity of the radar source, both alert LED’s will
activate. After you pass the source the front LED
and alert tone will go silent, while your rear LED
light continues to flash and the alert tone switches
to a “Brap” tone for the duration of the encounter.
