cooper Avanti?

Hi there Lads, hoping you could guide me through a few problems with my father and mother in laws alarm;

First of all can I just describe the panel; it is a avanti panel, there is a blank box in the cellar, LCD panel at front door with a red light on it

Replaced battery for them yesterday and noticed the time and date are wrong and I was just wondering how I change it ive got a downloaded manual but the keypad layout is rather confusing so I was hoping you could talk me through it

2nd of all the stobe only flashes when in alarm once you put the code in it stops even before resetting it, how do I change that setting?

Advice will be much appreciated chaps
