INSTALLATION  
MOUNTING GUIDELINES  
Follow these guidelines when selecting a location.  
• Choose a location that does not block the driver’s view of  
the road.  
• Mount the detector in a level position with a clear view to  
both the front and rear.  
• The detector’s view of the road must not be blocked by any  
metal object.  
• Some vehicles have InstaClear or ElectriClear defogging  
windshields, which have metal coatings that block signals.  
General Motor’s APV vans have a solar shield that keeps  
the vehicle cooler during the summer, but also blocks sig-  
nals. A detector installed in a vehicle with any of these fea-  
tures will probably not detect a signal.  
• Since window tinting reduces the received strength of laser  
signals, you should not mount the detector behind any  
tinted glass.  
• Do not mount the detector where the driver or a passenger  
might hit it in a sudden stop or accident.  
Caution: Whichever mounting method you choose, place the  
detector out of view when you leave the vehicle. This keeps  
the detector out of sight of thieves and prevents exposing it to  
extremely high temperatures, which can temporarily impair  
performance.

HOOK-AND-LOOP TAPE MOUNTING  
For some dashboards, the hook-and-loop tape included with  
your detector might be best for mounting. Follow these steps to  
use the hook-and-loop tape.  
1. Use a damp cloth to clean the bottom of the detector and  
the dashboard. Let both surfaces dry.  
Note: The tape’s adhesive might not stick to a surface  
treated with vinyl cleaner or protectant.  
2. Remove the tape’s backing and stick the tape to the bottom  
of the detector.  
Note: Do not place the hook-and-loop tape over the detec-  
tor’s serial number.  
Serial  
Number  
On a curved dashboard, cut the supplied strip in half and  
use one strip on each side of the bottom of the detector.  
3. Remove the backing from the other side of the tape and  
press the detector onto the dashboard.

WINDSHIELD MOUNTING  
The supplied suction-cup windshield bracket lets you easily  
mount the detector on the windshield.  
Caution: Do not use the bracket in a vehicle that has a plastic  
coating on the windshield designed to protect passengers dur-  
ing an accident. If you use the bracket on this type of wind-  
shield, you might permanently mar the windshield’s surface.  
1. Align the groove in each suction  
cup with the slots in the wind-  
illus of suction cup  
shield bracket and slide the suc-  
installation in  
tion cups out until they lock into  
place.  
windshield bracket  
2. Clean the selected windshield  
area, position the bracket on the  
windshield, and press firmly on  
each suction cup to secure it in  
place.  
3. Slide the detector onto the base  
plate until it snaps into place.

CONNECTING POWER  
Caution:  
• Use only the supplied power cord. If your power cord is lost  
or damaged, you can order a replacement cord from your  
local RadioShack store.  
• Before plugging the power cord’s cigarette-lighter plug into  
your vehicle’s cigarette-lighter socket, make sure the plug’s  
tip is screwed firmly onto the plug. See “Replacing the  
Fuse” on Page 23 for more information about the cigarette-  
lighter plug.  
• Unplug the power cord’s cigarette-lighter plug from your  
vehicle’s cigarette-lighter socket when you turn off the igni-  
tion. This prevents your vehicle’s battery from being drained  
if you leave the detector on when you turn off the ignition.  
Plug the supplied power cord’s barrel plug into the detector’s  
power jack. Then plug the cord’s cigarette-lighter plug into your  
vehicle’s cigarette-lighter socket.  
Note: If the detector does not operate when you turn it on,  
remove the cigarette-lighter plug from your vehicle’s socket  
and check the socket for ashes and other debris. Also check  
the fuse in the cigarette-lighter plug and your vehicle’s fuse  
block (see “Replacing the Fuse” on Page 23).

MUTING ALERTS  
While a radar, laser, or safety warning alert is sounding, you  
can press MUTE to temporarily silence the detector for the cur-  
rent alert and any new alert that it receives within 20 seconds.  
Visual alerts are not affected.  
USING AUTO QUIET  
Auto Quiet reduces the selected audio level to a clicking alert  
about 5 seconds after it detects a radar signal. The clicking  
alert sounds at the minimum level for any new signal received  
within 20 seconds. VG-2 or laser alerts are not affected.  
To turn on Auto Quiet, press MUTE when the detector is not  
sounding an alert. The detector displays AUTOthen QUIET.  
To turn off Auto Quiet, press MUTE when the detector is not  
sounding an alert.  
SELECTING THE CITY AND  
HIGHWAY MODES  
Your detector’s CITY and CITY 1 modes are designed to  
reduce annoying false alerts triggered by automatic door  
openers, intrusion alarms, and other devices that share fre-  
quencies with police radar. In the CITY 1 mode, only X-band  
sensitivity is lowered.  
Note: The city modes have no effect on laser or VG-2 opera-  
tion.  
13  
 
To select the CITY mode, press CITY once. The detector dis-  
plays CITY. If the detector receives a weak speed/safety radar  
signal in the CITY mode, it beeps twice, then remains quiet  
unless the signal becomes very strong. If the signal strength  
increases, the detector again beeps twice.  
To select the CITY 1 mode, press CITY twice. The detector dis-  
plays CITY 1.  
To cancel the city modes, press CITY a third time. The detector  
displays HIGHWAY. The highway mode provides maximum  
alert response for open-road driving.  
DIMMING THE DISPLAY  
To dim the display, press DARK once. The detector displays  
DIM, then the display dims.  
To make the display black out, press DARK again. The detector  
displays DARK, then blacks out. The display dims when it is  
not detecting a signal, and blacks out entirely while it is receiv-  
ing a signal and for 20 seconds after the signal.  
Press DARK a third time to restore the display to full bright-  
ness.  
14  
 
SETTING THE VG-2 OPTION  
VG-2 is a system used by some law enforcement agencies to  
detect the use of radar detectors in vehicles. The VG-2 system  
detects the weak radio signals used in radar detectors. Your  
radar detector can sense a VG-2 system and shift its operating  
frequencies out of the range detected by VG-2, making your  
radar detector essentially invisible to this system.  
To turn on the VG-2 option, hold down DARK for 2 seconds.  
The detector displays VG2ON.  
Press DARK again to turn off the VG-2 option. The detector  
displays VG2OFF.  
Notes:  
Your detector does not detect speed radar when VG-2 has  
been detected.  
• If you want to use the VG-2 option, you must turn it on when  
you turn the detector on.  
RECEIVING AND IDENTIFYING  
ALERT SIGNALS  
Your detector gives different audible and visual alerts for each  
signal. In addition, the alert tone pulse rate increases with sig-  
nal strength and the detector displays a digit from 1 to 9 to indi-  
cate the signal strength (1 is weakest and 9 is strongest).  
When your detector senses instant-on radar, it sounds an  
intense, 3-second tone and displays PULSE.  
15  
 
Safety Radar Alerts  
Your radar detector detects all safety radar including the new  
Safety Warning System. This system provides advanced warn-  
ing of hazards and lets you respond appropriately to potentially  
dangerous conditions.  
Note: Not all areas have Safety Warning System transmitters.  
Your radar detector only alerts you to hazards if the area you  
are in has transmitters sending signals.  
When your radar detector encounters safety radar, it sounds a  
distinctive tone and displays the signal strength. In addition,  
your radar detector displays CAUTIONand informs you of the  
type of hazard by displaying one of 60 defined messages.

Laser Audio/Visual Alerts  
When your radar detector detects a laser signal from ahead or  
behind, the laser audio sounds and the radar detector displays  
LASERfor as long as the signal is present (for a minimum of 3  
seconds).  
Any laser alert, regardless of duration, requires immediate  
action! If you are the targeted vehicle, a laser gun can often  
determine your speed within seconds after you receive an  
alert. However, if you are traveling near or behind the targeted  
vehicle and receive an alert, you should have time to respond.  
19  
 
USING STAY ALERT  
Stay Alert helps you test your alertness behind the wheel by  
sounding beeps and asking if you are alert.  
Warning: Stay Alert is not intended as a substitute for ade-  
quate rest. You should not operate a motor vehicle if you are  
drowsy. During extended periods of vehicle operation, you  
should take frequent breaks. Improper reliance on the Stay  
Alert feature might result in vehicle damage, personal injury, or  
death. Never operate a vehicle if you are drowsy.  
1. Hold down CITY for 2 seconds until the detector displays RU  
ALERT, then rings.  
2. When the detector rings, press DARK, CITY, or MUTE within  
3–5 seconds.  
If you press DARK, CITY, or MUTE within 3–5 seconds, the  
detector rings again every 30–60 seconds.  
If you do not press a button within 3–5 seconds, an alarm  
sounds and the detector displays GET REST.  
3. To turn off Stay Alert, turn off the detector.

TROUBLESHOOTING  
If you have problems operating your radar/laser detector, the  
suggestions in this section might help. If you cannot solve the  
problem after trying these suggestions, take your detector to  
your local RadioShack store for assistance.  
If the detector does not turn on:  
• Be sure all power connections are secure.  
• Check the fuse that controls power to the cigarette-lighter  
socket. See your vehicle’s owner’s manual.  
• Check the fuse in the cigarette-lighter plug. See “Replacing  
the Fuse” on Page 23.  
• The cigarette-lighter socket might be dirty. Clean it to give a  
good, clean connection.  
Caution: Do not place any metal object other than the ciga-  
rette lighter or a cigarette-lighter plug in the cigarette-lighter  
socket. Doing so could blow a fuse in your vehicle or cause  
the metal object to become very hot.  
If the detector gives a false alert when the vehicle hits  
bumps in the road:  
• Check the power connections.  
21  
 
If the detector gives a false alert when you use accesso-  
ries such as power windows, motorized mirrors, brakes,  
and so on:  
• Check the vehicle’s electrical system, including the main  
battery cable and alternator connections.  
• Install a filter capacitor (1,000 µf, 35 volts, such as Cat. No.  
272-1032) on the back of the cigarette-lighter socket, across  
the power connections.  
If the detector performs the power on self-test (see “Turn-  
ing the Detector On and Off” on Page 12), but does not  
respond to radar signals when you see a police car:  
• A police car might not be equipped with radar, or might be  
using instant-on radar and not have the radar gun triggered  
(see the separate booklet Questions and Answers About  
Vehicle Speed Detection).  
• Police might be using VASCAR-type speed detection (see  
the separate booklet Questions and Answers About Vehicle  
Speed Detection).  
If the detector has poor laser detection range:  
• Be sure the laser detection lenses are not blocked.  
• Use lens-cleaning solution to clean the laser detection  
lenses and the windshield.  
22  
 
REPLACING THE FUSE  
If the detector stops operating, check the fuse in the DC power  
cord’s cigarette-lighter plug. If it has blown, follow these steps  
1
to replace it with a 2-Amp, 11/4 × /4 mm, fast-acting fuse (Cat.  
No. 270-1007).  
Caution: Using a fuse that does not meet these ratings or  
defeating the fuse protection can damage your detector or the  
vehicle’s electrical system.  
1. Carefully unscrew the tip of the cigarette-lighter plug.  
2. Remove the tip from the cigarette-lighter plug, then remove  
the old fuse.  
Note: Take care not to lose the spring inside the holder or  
the metal ring.  
3. Replace the fuse.  
4. Press the cigarette-lighter plug’s tip down into the body,  
then screw it back in.  
Caution: Be sure you press the cigarette-lighter plug’s tip  
down before screwing it in, or you might damage the plug.
