What does spector alert mean on my radar? - XRS 9330 Radar Detector

They are different frequencies that the police radar guns can use.

• X Band, 10.500 - 10.550 GHz
• K Band, 24.050 - 24.250 GHz

In the same way that you can have different radio stations that are different frequencies, there are different radar guns that use different frequencies to determine your speed. Radar detectors are designed to pick up these frequencies to alert you when one may be in use in the area.

cobra can tell u that cobra .com or uniden.com

See Whistler's FAQ page for the meaning of the alerts and the bands the unit receives. Radar Bands (X, K, Ka)- What do they mean? Click on this FAQ and it will explain it all to you.

The display just shows you the different types of radar bands it is detecting. For example, the is an X band, a K band, a KA band and so forth. All it is, is a different frequency of radar being used.

find a mobile speed trailer somewhere in a neighborhood just because it doesnt alert when you are next to a patrol car doesnt mean it isnt working 9 out of 10 the radar gun isnt on in the car or the gun is set to alert at a higher speed than what you are doing
i always check mine at the mobile speed trailers that the cops set up in neighborhoods

by going off do you mean alerting you or is the power turning off if it is alerting you you may have electronic interference in the car if the power is going off it may be as simple as a short in the power cord
cobra 773-889-3087 sells then for 10.00 or you can trade your old detector to them and get the next highest model at a discounted price

POP is a type of radar mode which only a couple of radar guns have. In essence, radar gun in POP mode emits an extremely brief signal to measure a car's speed. This brief signal lasts for less than 1/5 of a second. POP mode can not legally be used to write speeding tickets since it is not as accurate as the radar gun's normal operating modes, and since POP mode provides absolutely no radar tracking history.

Most people turn off POP mode in their radar detector's options since POP radar is very rarely encountered and since users experience excessive false alerts with POP turned on.

Spectre refers to the Spectre radar detector detector (RDD) which police use to locate drivers who are using radar detectors. The current Spectre models in use by law enforcement are the Spectre III and IV models. Some Cobra radar detectors claim to be able to detect the Spectre I. This is of no value since all Spectre I RDDs have been upgraded to later Spectre models which Cobra radar detectors can not detect. In short, turn Spectre detection off since this feature is a needless source of false alerts.

Radar detectors are not police detectors. Radar detectors only alert to police when the police have their radar guns turned on. Most police officers operate their radar guns in "instant-on" mode rather than leaving their radar guns turned on continuously. Instant-on operation involves very briefly turning the radar gun on for up to a second or two in order to get a vehicle's speed.

Cobra radar detectors are known to have great difficulty detecting the 35.5 Ka band radar gun frequency. This should be considered a serious problem since 35.5 Ka is the second most popular Ka radar gun frequency following the most commonly encountered 34.7 Ka radar gun frequency. There isn't much that Cobra can do about this issue since their competitors hold all of the really good patented solutions for detecting 35.5 Ka police radar while ignoring false alerts caused on this frequency due to other radar detectors.

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.

I again assume the above model number......
Hope this helped some...
