Need the operators manual for a cobra SPX 5500 radar detector

It is a radar detector, not a radio. You are in the wrong area. I honestly cannot figure out why a radar detector would ever need to be reset. The Cobra website does ot have your manual. Try the SPX6700

Found one here:

Cobra XRS 9990 User Manual

Unfortunately, Cobra does not provide secondary or tertiary manuals on their website for this old model of Laser Detector.

Your best bet would be to either purchase a new Laser/Radar detector from Cobra and get the manual from that.

Hope this helps.

Thanks!

Here is a link to the Cobra Radar Detector Manual you are trying to find:

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.

Here is a link to Cobra's RD product manuals page:

To the original poster, the officer could have used laser, vascar, or pacing to issue a speeding ticket. The officer also could have used a very quick burst of instant-on radar which Cobra brand radar detectors are notorious for not detecting. The officer also could have used a 35.5 Ka band radar gun. Cobra and other import brands of radar detectors usually have great difficulty detecting 35.5 Ka band radar.

The Cobra XRS-757 is the same as the Cobra XRS-9330. The difference in model number is due to the 757 being sold at Wal-Mart stores.
