Toilet cistern - How does it fix to wall?

[JohnBailey]

Hi,
I am fitting a PJH Purity toilet, bought through B&Q, and although the cistern fits to the toilet pan there are no fixings to attach the cistern to the wall, not even any holes. This doesn't seem right, when I did a test-install before drilling the holes in the floor the cistern wobbles as I walk across the floor.
Is it supposed to fix to the wall, and if so, how?

if it has no holes to screw through then silicone..a couple of blobs near edges, so they could be cut with a long knife if required to be removed
