New to a RR , is there any way of stopping the beeping when you turn it on and off ??

I know there is 2 faults.

1. It says alarm fault , a new motion sensor for the interior came with the car but it hasnt cured it.

2. It says l/h front window not set,now i have done the up/down hold button thing but it doesnt go away.
The window works fine it just doesnt one press open or close.

Any idea would be great.
Cheers
Paul
