I'm at work at the mo but from memory. Push the reset button for a few seconds till the LED flashes and release it to reset any current programme. To set the memory make sure the light is off. Hold down on the on/off button (light comes on) the LED flashes and then push the other button (whilst still holding on/off) for the amount of hours you want to the delay to last. i.e. if you set it at 11am and push the delay once it will come on at 12pm everyday, push it twice and there will be a two hour delay from 11am. Release the on/off button once you have done this and the LED will flash to confirm memory has been programmed.
Whilst the light is on, hold down on/off and repeat the above to set the light to switch off. Hold down on/off till the LED flashes and push the other button 9 times and this will give you 9 hours of light. Let go of the on/off button and the light goes out, LED flashes and you're programmed.
Hope this helps. Instructions are in the book and a must admit it took a couple a cups of tea and a bit of experimenting before I cracked it.
