Ikea oven's timer doesn't ring: Lattskott Hygienisk

[MeeWhoo]

Hi,

I was wondering whether someone else has this oven and whether their times does any kind of noise when it finishes, as it is driving me mad that when the time runs out, it just turns itself off without any kind of audible warning.

I've checked the manual and it doesn't mention anything about a bell or noise, so I am wondering whether my timer is not working properly or whether this is a design flaw.
