Power ConnectionTo apply power to the STi, plug the smallend of the power cord, (telephone-typeconnector) into the modular jack on theSTi’s right side, and plug the lighter plugadapter into your vehicle's lighter socket oraccessory socket.Your STi operates on 12 volts DC negativeground only. The lighter plug provided is astandard size and will work in most vehicles. However, some vehicles mayrequire the optional European sleeve toensure a snug fit. If so, simply call ourservice department to order one. Thissleeve slides over the Power cord’s lighterplug adapter. Of course, your lighter socketmust be clean and properly connected forproper operation.Mounting LocationWhere to mount STiFor optimum detection performance, werecommend the following:• Using the Windshield QuickMount, mountyour STi level, and high enough on yourfront windshield to provide a clear view ofthe road from the front and rear.• Mount the STi away from windshieldwipers, other solid objects, and heavilytinted areas that might obstruct the radarantenna or laser lens.6InstallationWindshield QuickMountThe STi’s QuickMount windshield bracket isdesigned for unobtrusive and hassle-freemounting. 1Depress the adjustment button on thetop of the STi (by the word BELTRONICS)and slide the QuickMount bracket into theslot until it is locked into the position whichbest fits the angle of your windshield (thereare four settings available). For extremelyhorizontal or extremely sloped windshields,the QuickMount bracket can be bent.To ensure that the suction cups adhere to the windshield firmly, be sure to keep both your windshield and the suction cups clean.2To adjust the STi on your windshield,use the QuickMount adjustment buttonlocated on the top of the STi, and slide theSTi forward or backward to obtain a level position.When installed and adjusted properly, theback top edge of the STi should rest solidlyagainst your windshield.User’s TipYou can leave the QuickMount bracket inplace on your windshield, and easilyremove STi by pressing the adjustmentbutton and sliding the STi off the mount.Again, be sure to position the bracketwhere it won’t present a hazard in the eventof an accident. Additional mounts are available.7N0TE: Depending on your vehicle, thelighter socket power may either be continuously on, or it may be switchedon and off with your ignition switch.CAUTION: A few vehicles (including somePorsches) have windshields with a softanti-lacerative coating on the insidesurface. Use of suction cups will permanently mar this coating. Consultyour dealership or the vehicle owner’smanual to determine if your windshieldhas this coating.WARNING: BELTRONICS cannot anticipate the many ways STi can bemounted. It is important that you mountSTi where it will not impair your viewnor present a hazard in case of an accident.STi Manual 3/28/05 3:39 PM Page 9
Controls and FeaturesPowerTo turn STi on or off, press the PWR buttonlocated on the front left side. When youturn STi on, it goes through a sequence ofalerts.If you prefer, you may program yourSTi for a shorter power-on sequence. Seethe Programming section for details.VolumePress and hold the VOLUME/MUTE button,located in the center of the front panel, toadjust the STi’s alert volume level. Theaudio will ramp up and down, accompaniedby a bar-graph on the display. Once you’vereached your preferred audio level, simplyrelease the button.Power-on indicationAfter STi’s start-up sequence is complete,the alphanumeric display will showHighway, AutoScan, City or City NoX toindicate which sensitivity mode is selected.If you prefer, you can select alternatepower-on displays. See the Programmingsection for details.Voice AlertsThe STi provides digital voice announcements (factory default) for alerts. If you prefer, you can turn off the voiceannouncement feature and have the STiprovide audible tones without the voiceannouncement. See programming sectionfor details.AutoMuteYour STi has our patented AutoMutefeature. After STi alerts you to a radarencounter at the volume you have selected,the AutoMute feature will automaticallyreduce the volume to a lower level. Thiskeeps you informed without the annoyanceof a continuous full-volume alert.If you prefer, you can turn theAutoMute feature off. See the Programmingsection for details.MuteThe VOLUME/MUTE button, located in thecenter of the STi’s front panel, allows you tosilence the audio alert during a radarencounter.To mute the audio for a single specificsignal, briefly press the VOLUME/MUTEbutton. After that radar encounter haspassed, the mute will automatically resetand the audio will alert you to the nextencounter.8Sensitivity Button (SENS)The “SENS” button selects the STi’s sensitivity mode. We recommend AutoScanmode for most driving.Highway Mode (Highway)In this setting, the STi will detect all signalsat maximum range.AutoScan Mode (AutoScan)In this setting the STi's internal computercontinuously analyzes all incoming signalsand intelligently filters out unwanted X andK-band false alarms from automatic dooropeners and motion sensors. Fullsensitivity is maintained on all other bandsCity (City STD)In this setting, X and K-band sensitivity isfurther reduced to eliminate unwanted falsealarms in congested urban areas. City No X (City NoX)In this setting, K-band sensitivity is the sameas City STD, however, X-band is completelyturned off.9BrightnessThe STi’s brightness is controlled by aphotocell located behind the front displaylens. This photocell will automatically adjustthe display and backlit buttons based on theambient light in your vehicle. If you prefer,you can select a fixed brightness level,including Full Dark Mode. See the programming section for details.WARNING: Do not use the STi in thismode unless you are absolutely certainthat there are no traffic radar guns usingX-band in your area.Photocell locationSTi Manual 3/28/05 3:39 PM Page 11
Controls and Features10Power ConnectorThe STi’s power jack uses a telephone-typeconnector. This 4-conductor connectoronly works with the included SmartPlug oroptional direct-wire, or our standard powercord.For more information or to order, callus toll-free at 1-800-341-2288.Signal Strength Meter The STi’s alphanumeric display consists of280 individual LEDs, to provide an intuitiveultra-bright display of signal strength andtext messages.The STi’s standard bar-graph signalstrength meter only displays information ona single radar signal. If there are multiplesignals present, STi’s internal computerdetermines which is the most importantthreat to show on the bar-graph meter.When STi detects radar, it displays theband (X, K, Ka), and a precise bar-graph ofthe signal strength. When the STi detects alaser signal, the display will show “LASER.”When it detects a POP signal, the displaywill show “POP.”Threat DisplayYour STi’s Threat Display option is anadvanced display for experienced detectorusers. Please use the STi for a few weeks toget familiar with its other features beforeusing Threat Display.To use the Threat Display instead ofthe bar graph signal strength meter, youmust select Threat Display in the STi’sProgramming (see pages 12-15).The STi’s Threat Display simultaneously tracks multiple radar signalsand their relative signal strength. Threat Display can help you spot achange in your normal driving environment;for example, a traffic radar unit being operated in an area where there arenormally other signals present.The Threat Display is actually a miniature spectrum analyzer. It shows whatband each signal is and its signal strength.Ka9K2X1Above is the Threat Display if the STiwas detecting a strong Ka-band, a weak K-band, and a weak X-band signal.11A few more examples will help youbetter see how the Threat Display works.K9 X1Here Threat Display shows a strong K-band signal, and a weak X-band signal.Ka1 X9Here Threat Display shows a weakKa-band signal, and a strong X-bandsignal.Threat Display DetailsThe band designators (X, K, Ka) willstay on the display for a few seconds afterthe signal has passed. This allows you to seewhat the unit detected, even on very briefsignals.Tech DisplayThe STi’s Tech Display option is for theexperienced detector user. In this mode,the STi will display the actual numericfrequency of the radar signal beingreceived.K 24.150Tech Display shows one K-band signalat 24.150 gigahertz.Even long-time detector users willrequire a significant amount of time to getfamiliar with this new level of informationabout detected signals.Audible AlertsFor Radar signals:The STi uses a geiger-counter-likesound to indicate the signal strength andtype of radar signal being encountered.When you encounter radar, a distinctaudible alert will sound and occur faster asthe signal gets stronger. This allows you tojudge the distance from the signal sourcewithout taking your eyes from the road. X-band = chirpingK-band = buzzingKa-band = double-chirpPOP = full double-chirpSWS = double buzzFor Laser signals:Since laser signals are a possible threatno matter how weak, the STi alerts you tothese bands at full signal strength.For POP signals:Since POP signals are a possible threatno matter how weak, the STi alerts you tothese bands at full signal strength.For Safety signals:The STi will alert you to these signalswith a double-beep tone, and a corresponding text message. A completelisting of the text messages is on page 23.NOTE: If you are operating the STi in theDark mode, the display will not displayanything when a signal is detected. Onlythe audio, and the flashing alert lamp onthe SmartPlug will be seen.NOTE: If you use Threat Display, the briefsignal shown in the power-on sequencewhen you turn on your STi will also bein Threat Display: an X with a decayingnumeric signal.STi Manual 3/28/05 3:39 PM Page 13

BandsMODIn this setting, STi will warn you with anaudible alert, and associated text messagestating which band has changed from theoriginal factory setting (i.e. “SWS ON”).This warning is displayed during the startup sequence (standard or fast).WARNING: Do not turn off a band unlessyou are absolutely certain that there areno traffic radar guns using that specificband in your area.STi Manual 3/28/05 3:39 PM Page 19
Technical Details18Interpreting AlertsAlthough the STi has a comprehensivewarning system and this handbook is ascomplete as we can make it, only experience will teach you what to expectfrom your STi and how to interpret what ittells you. The specific type of radar beingused, the type of transmission (continuousor instant-on) and the location of the radarsource affect the radar alerts you receive.The following examples will give youan introduction to understanding the STi’swarning system for radar, laser and safetyalerts.ExplanationYou are approaching a continuous radarsource aimed in your direction. An instant-on radar source is being used aheadof you and out of your view. An instant-on radar source or laser source isbeing used nearby. This kind of alert requiresimmediate attention!Laser is being used in the area. Because laser isinherently difficult to detect, any laser alertmay indicate a source very close by. A moving patrol car with continuous radar isovertaking you from behind. Because thesesignals are reflected (reflections are increasedby large objects), they may or may not eventually melt into a solid point even whenthe patrol car is directly behind you. AlertThe STi begins to sound slowly, then the rateof alert increases. The Signal Meter rampsaccordingly.STi emits short alerts for a few seconds andthen falls silent only to briefly alert and fallsilent again. STi suddenly sounds a continuous tone for theappropriate band received. All segments in theSignal Strength Meter are lit.A brief laser alert. STi receives weak signals. These signals maybe a little stronger as you pass large, roadsideobjects. The signals increase in frequency.19ExplanationYou are approaching a radar unit concealed bya hill or an obstructed curve.A patrol car is traveling in front of you with aradar source aimed forward. Because signalsare sometimes reflected off of large objectsand sometimes not, the alerts may seem inconsistent. A patrol car is approaching from the otherdirection, sampling traffic with instant-onradar. Such alerts should be taken seriously. You are driving through an area populatedwith radar motion sensors (door openers,burglar alarms, etc.). Since these transmittersare usually contained inside buildings or aimedtoward OR away from you, they are typicallynot as strong or lasting as a real radarencounter.AlertSTi alerts slowly for a while and then abruptlyjumps to a strong alert.STi alerts intermittently. Rate and strength ofalerts may be consistent or vary wildly. STi alerts intermittently. Rate and strength ofsignal increases with each alert. STi gives an X-band alert intermittently.CAUTION: Since the characteristics of these alerts may be similar to some of thepreceding examples, overconfidence in anunfamiliar area can be dangerous.Likewise, if an alert in a commonly traveled area is suddenly stronger or on adifferent band than usual, speed radar maybe set up nearby.STi Manual 3/28/05 3:39 PM Page 21
Technical Details20How Radar WorksTraffic radar, which consists of microwaves,travels in straight lines and is easily reflectedby objects such as cars, trucks, evenguardrails and overpasses. Radar works bydirecting its microwave beam down theroad. As your vehicle travels into range, themicrowave beam bounces off your car, andthe radar antenna looks for the reflections.Using the Doppler Principle, the radarequipment then calculates your speed bycomparing the frequency of the reflectionof your car to the original frequency of thebeam sent out.Traffic radar has limitations, the mostsignificant of these being that it typically canmonitor only one target at a time. If there ismore than one vehicle within range, it is upto the radar operator to decide which targetis producing the strongest reflection. Sincethe strength of the reflection is affected byboth the size of the vehicle and its proximity to the antenna, it is difficult forthe radar operator to determine if the signalis from a sports car nearby or a semi-truckseveral hundred feet away.Radar range also depends on the powerof the radar equipment itself. The strengthof the radar unit’s beam diminishes withdistance. The farther the radar has to travel,the less energy it has for speed detection.Because intrusion alarms and motionsensors often operate on the samefrequency as X-Band radar, your STi willoccasionally receive non-police radarsignals. Since these X-Band transmitters areusually contained inside of a building, oraimed toward the ground, they will generally produce much weaker readingsthan will a true radar encounter. As youbecome familiar with the sources of thesepseudo alarms in your daily driving, theywill serve as confirmation that your STi’sradar detection abilities are fully operational.How “POP” Works“POP” mode is a relatively new feature forradar gun manufacturers. It works by transmitting an extremely short burst,within the allocated band, to identifyspeeding vehicles in traffic. Once the targetis identified, or “POPPED,” the gun is thenturned to its normal operating mode toprovide a vehicle tracking history, (requiredby law).21How Laser (Lidar) WorksLaser speed detection is actually LIDAR(Light Detection and Ranging). LIDAR gunsproject a beam of invisible infrared light.The signal is a series of very short infraredlight energy pulses, which move, in astraight line, reflecting off your car andreturning to the gun. LIDAR uses these lightpulses to measure the distance to a vehicle.Speed is then calculated by measuring howquickly these pulses are reflected given theknown speed of light. LIDAR (or laser) is a newer technologyand is not as widespread as conventionalradar, therefore, you may not encounterlaser on a daily basis. And unlike radardetection, laser detection is not prone tofalse alarms. Because LIDAR transmits amuch narrower beam than does radar, it ismuch more accurate in its ability to distin-guish between targets and is also more difficult to detect. AS A RESULT, EVENTHE BRIEFEST LASER ALERT SHOULDBE TAKEN SERIOUSLY.There are limitations to LIDAR equip-ment. LIDAR is much more sensitive toweather conditions than RADAR, and aLIDAR gun’s range will be decreased byanything affecting visibility such as rain, fog,or smoke. A LIDAR gun cannot operatethrough glass and it must be stationary inorder to get an accurate reading. BecauseLIDAR must have a clear line of sight and issubject to cosine error (an inaccuracy,which increases as the angle between thegun and the vehicle, increases) police typically use LIDAR equipment parallel tothe road or from an overpass. LIDAR can beused day or night.STi Manual 3/28/05 3:39 PM Page 23
Technical Details22How TotalShield™Technology WorksBel’s TotalShield Technology keeps RFsignals from radiating from the detector’santenna. Unlike other detectors, whichmerely move their RF signals (local oscillators) to another frequency (whichwill be detectable by future detector-detectors), this revolutionary design keepsyou unseen by the current VG-2, Spectre,etc. This unique design will also keep youunseen from any future radar detectordetectors as well.Although the Bel STi is a completely undetectable radar, laser and safetydetector, driving techniques and reactionsto alerts can still draw unwanted attention.Here are a few examples:1. Hitting the brakes immediately whenthe STi provides an alert can broadcast useof a detector.2. Visible power cords, brackets andsuction cup marks on the glass can alsoadvertise to others that you have a detector.3. Traveling at night with a bright redglow from a radar detector’s display visiblefrom outside your vehicle can also drawunwanted attention. The STi offersadjustable brightness, including a full darkmode which will provide audio alerts, butno visual indication except for the alert LEDon the SmartPlug.How Safety Radar WorksSafety Warning System, or SWS, uses amodified K-band radar signal. The SWSsafety radar system has 64 possiblemessages (60 currently allocated). The SWSmessages your STi can display are listed onthe facing page.From the factory, your STi isprogrammed with SWS decoding ON. IfSWS is used in your area, your STi willdisplay the safety messages associated withthe signal. If you do not wish to detect thissystem, use the Programming feature toturn STi's SWS decoding OFF.Note: some of the safety messages havebeen condensed, so that each message canbe displayed on one or two screens on STi’seight-character display.Since Safety radar technology is relatively new, and the number oftransmitters in operation is not yet wide-spread, you will not receive Safety signalson a daily basis. Do not be surprised if youencounter emergency vehicles, roadhazards and railroad crossings that areunequipped with these transmitters. AsSafety transmitters become more prevalent(the number of operating transmitters isgrowing every day), these Safety radarsignals will become more common.For more information and details aboutSWS safety radar, visit their web site atwww.safetyradar.com.23SWS Text MessagesHighway Construction or Maintenance1WorkZone2Road Closed3Bridge Closed4WorkCrew Highway5WorkCrew Utility6Detour7Truck Detour8MustExit9Rtlane Closed10 CntrLane Closed11 LeftLane Closed12 Future useHighway Hazard Zone Advisory13 Police14 Train15 Low Overpass16 BridgeUp17 Bridge Wt Limit18 RockSlid Area19 School Zone20 Road Narrows21 Sharp Curve22 Croswalk23 Deer Crossing24 Blind or Deaf Kid25 SteepUse LowGear26 Accident27 PoorRoad Surface28 Loading SchoolBus29 DontPass30 Dangrous Intrsect31 Emergncy Vehicle32 Future useWeather Related Hazards33 HighWind34 Severe Weather35 HeavyFog36 Flooding37 BridgIce38 RoadIce39 Dust Blowing40 Sand Blowing41 Blinding Snow42 Future useTravel Information/Convenience43 RestArea44 RestArea w/servic45 24hrFuel46 Insp Stn Open47 Insp Stn Closed48 Reduced Speed49 Speed Enforced50 HazMatls Exit51 Expect Delay52 10 Min Delay53 20 Min Delay54 30 Min Delay55 1 Hour Delay56 Traffic TunRadio57 Pay Toll58 Trucks ExitRght59 Trucks ExitLeft60 Future useFast/Slow Moving Vehicles61 Emerg Veh Moving62 Police Pursuit63 Oversize Vehicle64 SloMovng VehicleSTi Manual 3/28/05 3:39 PM Page 25
Troubleshooting24ProblemSTi beeps briefly at the same location every day, but no radarsource is in sight.STi does not seem sensitive to radaror laser.STi did not alert when a police carwas in view.STi did not provide a Safety signalwhile within range of an emergencyvehicle.STi’s display is not working.STi’s audible alerts are less loud afterthe first few alerts.STi bounces or sags on windshield.STi’s power-on sequence reoccurswhile you are driving. Your 14-year old son has changed all9 of the Programming options.Solution• An X-band motion sensor or intrusion alarm is located withinrange of your route. With time, you will learn predictablepatterns of these signals.• Make sure that windshield wipers do not block ST i’s radarantenna and that the laser lens is not behind tinted areas.• Determine if your vehicle has an Instaclear®, ElectriClear®orsolar reflective windshield which may deflect radar or lasersignals.• STi may be in City Mode.• VASCAR (Visual Average Speed Computer and Recorder) astopwatch method of speed detection, may be in use.• Officer may not have radar or laser unit turned on.• Safety transmitters may not be commonly used in your area.• Press the SENS button to deactivate Dark Mode.• STi is in AutoMute Mode. See page 8 for details.• STi is not making contact with the windshield to providestability. While holding down STi’s QuickMount button, slideSTi toward the windshield so that the back top edge makesfirm contact.• A loose power connection or dirty lighter socket can causeSTi to be briefly disconnected.• You can return all of the programming options to the factorydefaults by holding down the VOLUME/MUTE and SENSbuttons while you turn the STi on.25ProblemSTi will not turn on.STi feels very warm. Solution• Check the PWR is on.• Check that vehicle ignition is ON.• Check that vehicle lighter socket is functional.• Try STi in another vehicle.• It is normal for STi to feel warm.Explanation of DisplaysNo display STi is in the Dark mode (page 9, 16)PilotHWY One of the many programming messages (pages 12-16)WorkZone One of the many Safety Radar messages (pages 22-23)Caution STi has detected a Safety Radar Signal, but the signal isn’t yet strong enough to decode the specific safety message (page 22-23)Self Cal STi is running a self-calibration test Service STi has failed the calibration test.
