radar guns etc, use different Frequency in every country by there laws, ours is FCC.GOV
Lidar, Laser is more complex.
the GPS version are best as it has the location of the all , cams/traffic
but not hand held GUNS. those can go on in 1 second, and you are caught.

Cobra XRS 9990 User Manual

replace the speaker cobra sells them for a few dollars
773-889-3087 or cobra.com also if you want a new detector you can send your old one in and they will upgrade to the next higher model at a good discount ( a lot cheaper than buying through the stores .
the speakers are easy to install just plug in no soldering required .

send an email to [email protected] or you can call 773-889-3087 for their cust serv m-f 8-530pm cst. their website has other newer manuals for pdf download but unfortunately yours is unavailable

Most likely the speaker simply blew due to excessive heat. This is a fairly common problem with all makes and models of radar detectors. Contact Cobra. They should either be able to send you a replacement speaker which you can install yourself, or they should issue you a RMA so that you can send in your Cobra for service.

The easiest way would be to go to Radio Shack.

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.

The best way is to call up cobra or ask them a question through their site.
