How to operate the V3C range units (including the V3CW and V3CS models)
To open the power outlet, first 'wake up' the unit by holding down the top button for 3 seconds firmly with your thumb.
The top button is located on the center of the lid. It is indicated by a faint "power" symbol.
Once you have done this, the unit should be awake. Now you can simply press the top button once to open or close the unit.
After 2 minutes the unit will go back to sleep and will require re-awakening.
