How GPS Works
The Global Positioning System (GPS) is made up of
twenty four orbiting satellites and was developed by the U.S. military. There are at least four satellites visible at any given time every day.
A GPS receiver is designed to locate and receive data from four of these satellites. This data includes the distance to your location from each of the satellites. Once the distance from each satellite is known, the receiver can calculate and pinpoint your exact location.
How TotalShield Works
ESCORT’s TotalShield Technology keeps RF signals from radiating from the detector. Unlike other radar and laser detectors, which merely move their RF signals (local oscillators) to another frequency (which will be detectable by future
Although the PASSPORT 9500ci is a completely undetectable radar, laser and safety detector, driving techniques and reactions to alerts can still draw unwanted attention. Here are a few examples:
1.Hitting the brakes immediately when the 9500ci provides an alert can broadcast use of a detector.
2.Traveling at night with a glow from a radar detector’s display visible from outside your vehicle can also draw unwanted attention. The 9500ci offers adjustable brightness, including a full dark mode which will provide audio alerts, but no visual indication.
How TrueLock Works
TrueLock uses exact position and the actual frequency of a signal to eliminate it as a false alarm. Once a signal is locked out, a box is created (approximately a 1⁄2 mile radius) around that location to lock it out from all directions.
NOTE: Thoroughly look around and make sure that no real radar is being used to monitor your speed before you manually lock out a signal.
Automatic door openers use more than one source, so TrueLock will automatically lock out other X and
If you accidentally lock out a real threat, (visually see the officer) simply press and hold the Mute button to unlock it from PASSPORT’s memory.
How AutoLearn Works
AutoLearn uses TrueLock to lock out false alerts, however signals are locked out automatically over time vs. manually using the Mute button.
As you drive, PASSPORT records location and frequency for each signal detected. If that same signal (by frequency) is in the same location approximately three (3) times, AutoLearn will automatically lock it out as a false alarm. A “stored” message will be displayed, accompanied by a
How Auto Unlearn Works
Auto Unlearn automatically unlocks stored TrueLock signals if they are not present in the same location. This is particularly useful if you accidently lock out a true threat, or if an officer is parked in a shopping mall with automatic door openers.
