THERE'S A REMOTE POSSIBILITY...

...that we'll have sussed these all out by the time we leave, but I doubt it.

A & J's house is a gadget-lover's dream and there's a collection like this together with related TVs, DVD & other 'entertainment' equipment in nearly every room. We've got the lighting and heating sorted (mainly by finding and using the switches on the wall!), and we've managed to turn off the big clock that projects the time onto the wall in the bedroom at the click of a button. They left detailed instructions, but life's too short. They're not radio people, though, so I'm glad I brought my own (I always travel with a radio).
