got a cobra alarm (from the globe 3900 range will find out exact model tomorrow),it got fitted to my '56' fabia yesterday but i could only pick car up this morning.

brought it home and between 10am and 1pm it went off 5 times for no reason whatsoever.it's going back to the dealers on Monday but could anyone give me an idea whats up with it ?

thanks

Ultrasonics over adjusted maybe?

thats what i'm thinking.how can i adjust it ?

it the 3990 model.

thanks

Did they give you a manual with it? All the alarms I've had fitted have come with them and have detailed instructions on how to setup sensitivity and proximity
