How do I use Goodknight Power Chip Gel Tray?
Open the Goodknight Power Chip System pack and the Chip sachet inside. Simply insert the Goodknight Power Chip Gel Tray inside the machine. Do not tamper with or remove the transparent film on the Gel Tray. Plug the machine in with Gel Tray side up and switch on. The Chip needs to be replaced in 15 days, once the gel inside turns pale and cracks.
