Power Connection
• Plug the small end of the power cord into the
unit’s power jack.

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.

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.

may cancel the audio alarm by pressing Quiet.
• Press Quiet (when the unit is not alarming) to
cancel Auto 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.
OPERATION
City/City I/City II Mode

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.

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.
