Ok so i have had my CND lamp around 6 months and today i went to do a clients nails and when i pu her hand in and pressed the on button it went for a second then did a long beep, checked the bulb life and it was 0 do i replaced with my back up bulbs and it still did the same! How do i let my lamp know i have done this? I learnt in training and cannot remember and i have a client tomorrow please help me someone!!

Don't panic.... You just need to press and hold the reset button until you hear 3 beeps and the numbers will reset to 100.
