    Es imposible subir la sensibilidad,así de fábrica no sirve para nada suena si lo coges I te lo llevas no lo entiendo,las instrucciones no funcionan

  • Ian Hardwicke on

    I purchased one of these alarms for my motorcycle last year and have been very happy with it. Over the winter the batteries have died and I had to fit new ones. since fitting the new batteries the alarm is hardly audible.
    Any ideas if this can be reset or do I need to replace the alarm.

    Many thanks
