Sky digibox

[Suzannew]

Sky installed me a new box the other day, everything was fine until is starting making a high pitched bleep continuously.  They are coming out this week and I have done everything I can think of as far as unplugging, switching off etc etc.  Any idea how to stop this noise!!
