Try a power reset and see if this resolves the problem.

Turn off the AC power to the clock.

Remove the coin cell backup battery from the clock.

Press and hold the Enter/Time Set button for 10 seconds and then release.

Reinsert the coin cell battery and then switch on the AC power and see if you can adjust the time etc.

Here is a link to the user guide for your clock/radio which shows how to remove the coin cell battery. Ensure that you insert it back into its' holder the correct way if it happens to become dislodged when out of the clock.
