Oxford boss disk lock alarm

[Marmalade]

Just bought one of these, used, via ebay

It will not shut up.

If i lock it, put it down it's quiet but unlocked or locked, moving at all it's screaming.

I've seen a vid on utube that seems if I unlock it and open it up it's quiet but mine just keeps screaming. I've replaced the batteries but no difference

Is it likely to be faulty or is there a knack?

you can buy a new module for about £20 but i paid £40 for this as is and a new complete lock can be had for £67.

Thought i'd ask to see what people thought before emailing her the bad news

With my oxford one, you put the U bolt in 1way to arm the alarm, or the other way round to lock it but NOT set the alarm. Tried that?
EDIT: Sorry re-read your post. Yeah it should STFU when you unlock and remove the U Bolt
