How to operate the V3C unit
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.
