This little DAB Radio came in because the Power button had broken. It's a small rubber button which sits over a push switch on the board behind. The customer had lost the button some time ago and could not remember the colour of the button. I contacted Roberts Radio technical support, ordered a green button and waited for delivery.
It arrived several days later and dismantling and replacing it in the radio was a simple enough job, so I'll leave the video to explain it all.
