Ken,
I received a reply from Maplins which I have forwarded to you.
I have not tried this solution yet, as I will not be home again until Saturday next. If you want to wait until then & I will try it first. If you are going to go first, let me know how you get on please.
If we know it works, then we should post the solution up here and it might be of help to other people.
Regards.
