If your is anything like mine, then you need to set the clock. On mine there are 4 buttons, plus the twisty stick to actually make the adjustments, from left to right these are Alarm, Start, End and Hand (manual) - press the Start and End together and adjust with the twisty knob. If the clock fails to respond, Switch off at mains again and leave off for about 30 seconds before switching back on (I have had occasions when it has been switched off and back on too quickly and is unresponsive).
