My car had the votex alarm system factory fitted but i dont have any manual or descritpion on how it works.

I have a little keyring with votex on it which fits into a lug in the boot lining which turns the alarm sound on or off(doesnt work now though).I also have a little black box next to the gear stick under the gaitor which has a - and + adjuster on it which i assume is for sensativity?

up untill a few months ago it was working but now its stopped,i read somewhere on another forum while searching that theres a battery somewhere and when this goes flat it can leak.i also read on another forum that it plugs into the CCM and also controls the remote central locking?

does anybody have any info on the alarm system or a online manual as i dont have anything at all on it.i also read on another forum that it plugs into the CCM and also controls the remote central locking?

thanks
