Bought a car with a Cobra alarm fitted, but without alarm manual. Never had an alarm before and the small button just seems to set the alarm off and the large button sets the alarm OK but only turns the alarm off after about five minutes of pratting around in a car park. Any guidance appreciated or source of a manual would help as seen as Cobra does not seem to do downloadable manuals.

Hi,just to add to Rich answer. If your alarm has sensors fof movement inside the car then the small button also switches these off. Arm the alarm by pushing the large button & push the small 1 within 4 secs,should be a beep. Movement sensor is now off. Ie,if its hot out and you want to leave the windows down. Col

hi the small button is a personal panic button that automatically sets the siren off to ward away intruders, the actual arm, disarm of the alarm is by the large button, the length of time to arm and disarm could be one of two , low power in remote or recieving ariel is bieng shielded by bodywork, does it work easier the closer you are or from a particular side of the car? locate system and look for a wire that will be the antennae usually brown or black with a sealed end, check it is not obstructed and in a position to clearly pick up the signal if all ok there will probably be a need to change the remote battery, obtain correct battery,stand within two feet or sit in vehicle change battery quickly and code may be retained, press button if nothing happens, stand with remote touching screen pressing both buttons led on keypad will extinguish then flash takes between 10 and 30 seconds, you should be able to operate alarm as normal
