[. . . ] The Communications Act of 1934 guarantees your right to receive radio transmissions on any frequency. Local laws that contravene the Communications Act of 1934, while illegal, may be enforced by your local law enforcement officials until and unless they are prohibited from doing so by Federal Court action. WARNING: Before leaving your car, make sure that you conceal your radar detector. This will reduce the possibility of break-in and theft of your unit. Use of this product is not intended to, and does not, ensure that the motorist and any passenger will not be involved in a traffic accident. It is only intended to alert the motorist that an emergency or service vehicle equipped with a CODE 3 or Cobra Safety Alert Transmitter is in the area as defined by the range of the product. [. . . ] These sounds are demonstrated during the power-on sequence each time you turn your Cobra ESD-6000 on. Instant-on Detection The Cobra ESD-6000 is also designed to detect Instant-on speed monitoring signals. Power/Volume Control Plug the Cobra ESD-6000 power adapter cord into POWER connector. The POWER/VOLUME CONTROLon the left side of the Cobra ESD-6000 controls power and regulates the audible alert volume. Each time the unit is turned on, an automatic test pattern takes place: · This pattern consists of the Alarm Indicators and SIGNAL STRENGTH METER illuminating in unison with the audio alarm for two seconds. · The green POWER LED remains illuminated after the test sequence is completed. VG-2 Undetectable Some states or municipalities use devices referred to as "VG-2". The VG-2 device detects low level energy radiated by the internal oscillators of radar detectors. The ESD-6000 detects the VG-2's radiation before the VG-2 can detect the ESD-6000. The ESD-6000 then briefly turns off its internal oscillator, rendering it invisible to the VG-2, and alerts you to VG-2's presence. During these short intervals, the ESD-6000 is not able to receive radar or Safety Alert signals (laser reception is not affected). Band Alarm Indicators When the Cobra ESD-6000 detects an X-band radar signal, the red "X" Visual Alarm Indicator (LED) will flash in unison with the X-Band audio tone. When the ESD-6000 detects either a K-band or a Ka-band radar signal, the amber "K/Ka" Visual Alarm Indicator will flash in unison with the K or Ka Band audio tone. When the ESD-6000 detects pulses of laser light, the yellow "L" LED will flash in unison with the Laser tone. When VG-2 is detected, the amber "VG-2" LED will flash with an audio tone. When a Safety Alert signal is detected, all LEDs except POWER will flash. The detector will automatically reset to normal operation after the alert has passed. City/Highway The Highway/City function is controlled by a 2-step momentary button. The Highway mode is automatically engaged when the unit is powered up. To reactivate the Highway Mode simply press down on the Highway/City button again. The green LED will go dark to indicate that the detector is in Highway Mode. In the Highway Mode, your Cobra ESD-6000 operates at full sensitivity on all three radar bands plus laser. [. . . ] Since Safety technology is relatively new and the number of transmitters in operation is not yet widespread, you may not receive Safety alerts on a daily basis and should not be surprised to encounter some emergency vehicles, road hazards and trains that are not yet equipped with these transmitters and therefore fail to provide a signal. As Safety transmitters become more prevalent (the number of operating transmitters is growing every day), these Safety Alerts will become more common. LIDARs must have a clear line of sight to target a vehicle during the entire measurement interval. Intervening objects such as signposts, utility poles, tree branches, etc. , will prevent a valid speed reading. Yes, rain, snow, smoke, fog, and airborne dust particles will all reduce the effective range, and if sufficiently dense, may prevent its operation. [. . . ]
