Two possible answers:

1. Just click the mouse or hit ‘enter’ (‘return’) on the keyboard (sometimes the system just needs to ‘wake up’ and is designed to do so on a click or enter press).

2. Unplug the power to the KVM extender box, wait 20 seconds and re-plug the power in.

‘KVM extender’ – this is the system that links the PCs on the roof of the studios to the monitor, keyboard and mouse in the studio. There is one KVM extender for each PC. The KVM extender comprises of 1x receiver box connected to the PC on the roof and 1x transmitter box which is under the desk (by Guest seats in Studio B).
