PoolGuardSB swimming pool alarm

Maybe it is me not working this out properly, but I have struggled swith this so much.I really want it to work.In its design and styling, it is a great product, but I have really had problems.1 - as soon as I inserted the batteries it started making a racket.2 - I move it anywhere (even very gently) and it starts making a racket3 - even put it near the pool and it makes a racket4 - once in the pool, it started going off and the pool was stillIt was so noisy, that my neighbours called the police ( I have lovely neighbours by the way) and I was still only trying to set it up.I now have it sat on a shelf in my living room looking like an ornament - a very expensive red ornament....I am frightened to put it in the pool for fear of another police telling off.Yes, pool alarms are great, but surely they should not be this sensitive.It is a pity ince I really want this to work, and other reviews say that people are pleased with it - mine however is like a ticking time bomb that I am frightened to go near
