Buttons not reacting even after change of the battery

Buttons not reacting even after change of the battery
The display was there but the buttons were not working. I have unplugged, changed the battery but still nothing. It shows 1. 1. then 2103, then 0:00 and remains blinking. The buttons do not react.

ANSWERS:

After turning it on and setting the time , simply turn the radio on and back off…
Hey guys, struggled with this too, but found the answer on another forum.
