Power Connection

• Plug the small end of the power cord into the 

unit’s power jack.

• Plug the large end into the vehicle’s cigarette 

lighter.

Fuse Replacement

The lighter socket plug is equipped with a replaceable
2 amp 3AG fuse located behind the silver tip. To
replace the fuse, carefully unscrew the tip of the plug.

IMPORTANT: 

Unscrew slowly.  The tip 

contains a spring which may fly out when disas-
sembling. Insert the new fuse with the spring and screw
on the tip. With use, the screw cap on the plug
may loosen. Retighten it occasionally. 

Power On Self Test & Volume

Each time your Whistler detector is turned on, an
automatic self-test sequence confirms that the speak-
er and visual displays are functional. To increase the
volume, continue turning the 
volume knob.

sequence to cancel the self-test audio.  This will

test audio, simply press the Quiet button during

the next self-test.

Setting Saver (XTR-255/260/330) 

Setting Saver saves your personalized settings so

that when the detector is turned off and then on

again, you do not have to re-enter them.

Auto Quiet Mode

Pressing QUIET before a radar signal is detected

provides an alternate alert pattern, consisting of four

beeps (indicating X, K, Ka or Safety Radar) followed

by clicking.  The clicking will continue for as long as

the detected signal is present or any new signal is

detected within 20 seconds, becoming more rapid

as the strength of the signal increases.

• Press Quiet (before a signal is detected) to 

engage Auto Quiet. 

• Once the Auto Quiet mode is engaged, you 

may cancel the audio alarm by pressing Quiet.

• Press Quiet (when the unit is not alarming) to

cancel Auto Quiet mode.

Quiet Mode

Pressing Quiet cancels the audio during an alert and

any new alert within 20 seconds. After approximately

20 seconds,  2 beeps are provided on any new alert,

and the unit then remains quiet.

• Press Quiet to cancel the audio.
• Press Quiet a second time during an alert to restore the 

standard audio alert pattern; or turn the unit off, then on.

City/City I/City II Mode

Whistler’s Three Stage City Mode is designed to
reduce the annoyance of automatic door openers,
intrusion alarms and other devices which share fre-
quencies with police radar. Generally, X band is
used for these devices.

engage City Mode. The display will switch from
“H

otte

e: After 3 seconds, “II” or “IIII” City Mode

indicator turns off on the XTR-140.

• Pressing City button a fourth time cancels City IIII

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

remains quiet unless the signal becomes very

strong.  When the signal strength increases, two

additional beeps are provided. City II and City IIII

Modes operate the same as Highway Mode, but

in City II Mode, only the X band sensitivity is low-

ered. In City IIII 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 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.
