CAL7 is a broad self-test failure code. It will have to be sent to Escort for diagnostics on the specific problem unfortunately.

Dont know waht codes mean


By Codes do you mean the X, K and Ka signals that the unit is reporting? If so, those are the 3 bands used for police radar. X is the oldest and not used very much. K is also an older band. Ka however is the newer band and the most used for speed tracking.

What is Ka signal in my laser rader?


In 1983 the U.S. FCC allocated the spectrum from 34.2 - 35.2 GHz (Ka band) for traffic radar use, that same year Ka band photo (Across the Road) radars started appearing in the United States. Nine years later in 1992 the FCC expanded the Ka band spectrum allocated for traffic radar use to 33.4 - 36 GHz.

Ka band radars typically have more narrow beams than X or K band radars. Target detection range depends on moisture in the atmosphere (rain or humidity), the more moisture the less range.

Radar detector codes


When any detector "detects" radar, it will produce some form of Audiable sound. If someone is speeding, they need to slow down IMMEDIATELY if they want to avoid a ticket. It doesnt really matter if the radar gun is x, k, ka, ku, etc. You will probably get a ticket if you dont slow down.

Most dectectors will have indicators lights or displays that indicate the x, k, ka, etc., radar signals are actually being detected. This can provide SOME useful information. THe letters simply designate BANDS of frequencies that are used to send the radar beams. It is similar to changing the channel on a radio - k and ka bands use HIGHER frequencies for their radar signals.

X band is the oldest radar band and it is used for police radars AND door openers at supermarkets and other locations. If you drive by a supermarket, your radar detector is likely to go off and it is almost certainly going to be X band. CHeck it out next time you drive by a supermarket with an automatic door opener.

Since the police and the radar companies like to play cat and mouse, newer radar bands have been invented that OBSOLETE the older radar detectors. When the K bands showed up in the police radar guns, the radar detector folks had to have a new product offering that would detect X band and K band. And the race continues to go on even today and now, there are LASER police speed detectors and the new "RADAR" detectors now need LASER detectors as well. If you want to know the exact frequencies of these "bands" (K, Ka, etc), let me know and I will send them to you. But they are operating in the tens of GigaHertz regions.

Undersatanding the 12 bands of cobra xrs 797


Its all marketing hype. Cobra breaks up the three X, K and Ka bands into sub-bands, and they do the same for the single 904nm laser wavelength. There are no sub-bands for X or K band. In the USA, Ka band radar guns operate on three Ka band frequencies: 33.8, 34.7 nd 35.5 MHz. Cobra also breaks up the single laser band based on the known pulse rates of various laser gun models. Yet in general if you get a laser alert from a nearby cop then likely you have been tagged and will be getting a ticket.

"K" IS LOCAL POLICE BAND, "KA" IS STATE TROOPER, AND "X" IS SILENT ELECTRONIC ALARM SYSTEMS. HAVEN'T FIGURED OUT WHAT "VA-2 ALERT" IS YET.

Radar codes


VG-2 is a technology that police use to detect radar detectors. Detectors with this feature will detect when VG-2 is in use, and alert you to its presence.

AND

the x,k,ka codes you see flashing are......

X, K, and Ka Superwide are the radar bands that are used by police radar guns. X band was the first band used for by radar guns, but is now the least used. All radar detectors that we carry detect all 3 of these bands.

quoted by a professional at the Cobra industries for radar detectors, cb radios and electronics galore.

Signals


When "X" lights up, this means that your RD is either detecting X band police radar or that it is detecting an X band microwave automatic door opener.

When "K" lights up, this means the same as above except that the radar signal is a K band radar signal.

When "Ka" lights up, then this means that your RD is detecting police Ka band radar since no automatic door openers operate on Ka band.

When "VG-2" lights up, this is supposed to mean that your RD is detecting a VG-2 radar detector detector (RDD). Police use RDDs such as the VG2 and the Spectre to indicate that a motorist is using a radar detector.
