This is the back of the Roberts Sports DAB radio before starting.
Using a thin tool (for example a razor blade) lift the bottom edge of the back cover.
Carefully slide the back cover towards the bottom of the radio just a few mm then lift the back.
There are four small screws to be removed. Two black and two shorter silver. One of the black screws secures the aerial.
The inner cover hooks under the aerial so lift up from the side opposite the aeriel.
You now have access to the insides of the Robers Sports DAB 2.
