UNDERSTANDING YOUR DETECTOR
How Radar Works
Traffic radar, which consists of microwaves, travels in straight lines and is easily reflected by objects such as cars, trucks, even guardrails and overpasses. Radar works by directing its microwave beam down the road. As your vehicle travels into range, the microwave beam bounces off your car, and the radar antenna looks for the reflections.
Using the Doppler Principle, the radar equipment then calculates your speed by comparing the frequency of the reflection of your car to the original frequency of the beam sent out.
Traffic radar has limitations, the most significant of these being that it typically can monitor only one target at a time. If there is more than one vehicle within range, it is up to the radar operator to decide which target is producing the strongest reflection. Since the strength of the reflection is affected by both the size of the vehicle and its proximity to the antenna, it is difficult for the radar operator to determine if the signal is from a sports car nearby or a semi-truck several hundred feet away.
Radar range also depends on the power of the radar equipment itself. The strength of the radar unit's beam diminishes with distance. The farther the radar has to travel, the less energy it has for speed detection.
Because intrusion alarms and motion sensors often operate on the same frequency as X, and K-band radar, your detector will occasionally receive non-police radar signals. These transmitters generally produce much weaker readings than will a true radar encounter. As you become familiar with the sources of these pseudo alarms in your daily driving, they will serve as confirmation that your device's radar detection abilities are fully operational.
How Laser (Lidar) Works
Laser speed detection is actually light detection and ranging (LIDAR). Laser guns project a beam of invisible infrared light. The signal is a series of very short infrared light energy pulses that move in a straight line, reflecting off your car and returning to the gun. Laser uses these light pulses to measure the distance to a vehicle. Speed is then calculated by measuring how quickly these pulses are reflected, given the known speed of light.
Laser is a newer technology whose use is not as widespread as conventional radar; therefore, you may not encounter it on a daily basis. And unlike radar detection, laser is not prone to false alarms. Because laser transmits a much narrower beam than does radar, it is much more accurate in its ability to distinguish between targets and is also more difficult to detect. As a result, even the briefest laser alert should be taken seriously.
There are limitations to laser, however. Laser is much more sensitive to weather conditions than radar, and a laser gun's range will be decreased by anything affecting visibility, such as rain, fog or smoke. A laser gun cannot operate through glass, and it must be stationary to get an accurate reading. Because laser must have a clear line of sight and is subject to cosine error (an inaccuracy that increases as the angle between the gun and the vehicle increases), police typically use laser equipment parallel to the road or from an overpass. Laser can be used day or night.
TSR Signal Ranking Software
Your radar detector includes an optional boost in anti-falsing software to eliminate excessive alerts from erroneous K-band sources. One example of this is traffic flow monitoring systems. These systems, which are becoming more widely used in several countries, generate K-band signals to measure the flow of traffic on a given road. Unfortunately most detectors see this as a real threat and will alert you to it unnecessarily. Our proprietary TSR software, intelligently sorts, ranks and rejects this type of false alarm automatically. The result is ultimate protection without excessive false alarms.

Meter Mode
MAX 4 offers five different settings for displaying information about alerts.

Operation

Operation
Standard

The Standard meter mode provides only the band information and front signal strength information of a single alert. When radar is detected, the band (X, K or Ka) and a bar graph of the signal's strength are displayed. When laser is detected, the display will simply read "Laser." If there are multiple alerts present, only the highest priority threat is displayed. Laser is the highest priority threat, followed by Ka, K, then X band radar.
Spec

The Spec meter option is an advanced display for experienced detector users. In this mode, it will display the actual numeric radar frequency being received. Even long-time detector users will require some time to get familiar with this new level of information about detected signals. To use Spec instead of the Standard bar graph meter, you must select it (Spec) in Preferences.
Expert

ESCORT's exclusive Expert meter option is designed for the advanced detector user. In this mode, MAX 3 simultaneously tracks up to four radar signals. It shows each band along with a bar graph of its signal strength. In the image above, a Ka band, K band and two X bands are being detected with the greyed-out X band being a locked out false. Expert meter mode can help you spot a change in your normal driving environment (e.g., a traffic radar unit being operated in an area where there are normally other signals present).
Simple

Simple messages replace bands and signal strengths or frequencies:
Caution used when an alert is received while you are traveling below your current Cruise Alert setting (or posted speed limit for your current location when connected to Drive Smarter).
Slow Down displayed when an alert is received while you are traveling above the current Cruise Alert setting (or posted speed limit of your current location, when connected to Drive Smarter).
Tones
Standard
The factory default Standard alert tones uses a Geiger counter-type sound to indicate the signal strength and type of radar signal being encountered. When you encounter radar, a distinct audible alert will sound and will increase as the signal gets stronger. This allows you to judge the distance from the signal source without taking your eyes off of the road. Each band has a distinct tone for easy identification:
X band = beep tone
K band = brap tone
Ka band = double-brap tone Laser = solid brap tone
POP = solid brap tone
Standard Plus
Features the Standard alert tones outlined above for the primary alert, plus double-beep tones for additional alerts.
Mild
Mild alert tones off er softer, simpler alert tones that are less obtrusive to the driving experience:
X band, K band, Ka band and POP = Doorbell chime
Low signal strength = Double chime
High signal strength = Triple chime
If alert remains in area more than 15 seconds = Single chime (as a reminder)
Laser = Solid brap tone
Since laser signals are a possible threat no matter how weak, laser alerts are always full strength.

Operation

Operation
AutoMute
Your MAX 4 also includes ESCORT's patented AutoMute feature. Once MAX 4 alerts you to a radar encounter at your selected volume level, it automatically reduces the volume to the selected AutoMute level. This keeps you informed without the annoyance of a continuous full-volume alert. If you prefer, you can turn the AutoMute feature off.
AutoLearn™ Intelligence
The AutoLearn feature analyzes (over time) the source of radar signals by location and frequency. This allows MAX 4 to determine if a fixed location signal is a real threat or a false one. If it determines that the signal is an automatic door opener, motion sensor, etc., it automatically locks out this source at this particular location. A "Stored" message will appear on the display when a signal has been automatically locked out. AutoLearn needs to encounter the exact frequency in the same location approximately three times to lock it out. Since some door openers are turned on and off routinely, some variations may occur. Variations may also occur with seasonal temperature changes that can affects the frequency that these radar sources transmit.
MAX 4 will also unlearn signals to protect you from locking out real threats. If a particular signal is no longer present at a location that was previously locked out, MAX 4 will unlock that signal. If you prefer, you can turn the AutoLearn feature off.
GPS Filter (TrueLock)
MAX 4 is equipped with a TrueLock GPS Filter to store and lock out, or ignore, fixed location false alerts in its memory. Common sources of fixed location false alerts are storefront automatic door openers and motion sensors. The TrueLock GPS Filter will not lock out moving false alerts that are commonly caused by vehicle's blind spot monitoring and collision avoidance systems.
Locking Out False Alerts
To manually lock out a fixed location false alert (X band, K band or laser only), press the MUTE button three times during an alert. Pressing the first time will silence the audio. Pressing a second time will generate a prompt on the display that will read "Lockout?" Press a third time to confirm you want to lock this signal out by location and frequency. A "Stored" message will be displayed. Once a signal has been stored, MAX 4 will not audibly alert the next time you approach this area but will display the locked-out alert in grey.
Locked Out Alert

To unlock a signal that has already been stored, simply press the MUTE button twice while receiving the locked out alert. The display will read "Unlock?" when pressing MUTE the first time. Press the MUTE button again to unlock it from memory. The display will read "Unlocked" to confirm your action.
NOTE: When the GPS Filter is set to OFF, you do not have access to MAX 4's other GPS- enabled features (e.g., Defender Database alerts, marking locations, etc.).
AutoPower
This feature automatically turns off MAX 4 after a set period of time to save unnecessary drain on your battery. This is especially useful if your vehicle has a constant-power ignition. To turn MAX 4 on again you must press the power button.
NOTE: If AutoPower is on, to save screen life the display screen goes blank after 30 minutes without moving. The display screen will turn on automatically after you reach 10MPH.
Band Enables
In the factory default setting the suggested radar and laser bands for North America are monitored and sources of some common false alerts are rejected. It is highly recommended that you use your MAX 4 in this mode.
If you modify Band Enables then this setting will show Modified. The MAX 4 will also notify you during the startup sequence with an audible alert.
WARNING: Do not turn off any Band Enables unless you are absolutely certain there are no traffic radar guns in your area using that specific band.
K Notch
Reduces sensitivity of K band in the frequency range of 24.190 - 24.210 GHz. This is effective at reducing alerts to certain vehicle collision avoidance systems.
Shifters (only available when optional ZR5 or ZW5 laser shifters are connected)
Sets the shifter mode of operation. Receive = receive-only mode. Shift4/6/8/10 puts the laser shifters into receive-only mode after 4/6/8/10 seconds from receiving an alert. After 30 seconds of not receiving a Laser alert, the shifters automatically return to shift mode. You can also manually put the laser shifters into receive-only mode by double tapping the Mute button on the detector or SmartCord.
Marker Enables
MAX 4 gives advanced warning of upcoming markers at the following distances:
Red light cameras 250 ft or 10 seconds
Red light & speed cameras 250 ft or 10 seconds
Speed cameras 500 ft when traveling below 55 mph 1,000 ft when traveling above 55 mph
Speed traps 0.3 mi or approximately 1,584 ft
Other 500 ft when traveling below 55 mph 1,000 ft when traveling above 55 mph

Operation
To Mark A Location
- Press MRK. The display will read "Mark?" Press MRK again to bring up a menu of markers to choose from.
- Use the plus and minus buttons to scroll through the markers then press MRK to select the marker that you wish to use at this location.
- The display will read "Marked!"
Air Patrol locations cannot be marked by the user.
NOTE: When a location is marked the first time, you must travel at least 1 mile away from that location to receive an alert when you return to the area.

Troubleshooting
| PROBLEM | SOLUTION |
| Detector beeps briefly at the same location every day, but no radar source is in sight. | A motion sensor or intrusion alarm is located within range of your route. If you have AutoLearn enabled, the factory default setting, then MAX 4 will store this signal after about 3 passes and no longer alert to it. |
| Detector did not alert when a police car was in view. | Offi cer may not have radar or laser unit turned on. VASCAR (Visual Average Speed Computer and Recorder), a stopwatch method of speed detection, may be in use. |
| Detector's audible alerts become softer after the first few alerts. | Detector is In AutoMute mode. See "AutoMute" In the Settings & Preferences section for details. |
| The power-on sequence reoccurs while you are driving. | A loose power connection can cause MAX 4 to be briefly disconnected and will retrigger the power-on sequence. Check all connections. |
| You wish to restore the factory default settings. | Press and hold the MRK and BRT buttons while powering on the detector. A "Factory Settings Restored" message will display, acknowledging the reset. |
| The device will not turn on. | Check that vehicle ignition is on. |
| The display is blank. | MAX 4 is in Dark mode. Press the BRT button to adjust the brightness. |
