Product description
Light unit that fits both the Little Litecup and the Large LitecupThe light unit MUST always be taken off, whenever the cup is to go into the dishwasher, and it can be done very easily, as seen from the following:
Remove the light unit from the cup with a teaspoon or another stump material.
Remove the safety screw in the bottom of the light unit.
Turn the outermost part with a coin or spoon, so the unit points towards the hole for the safety screw. The battery cap will now loosen from the light unit.
Remove the battery and replace it with a new CR2032 (standard). Remember the side must turn upwards.
Put the battery lid and safety screw back in place.
