Once you recive your topper, you may have to put it together. (depending on how it was posted)
Place the topper into the base, with the engraving to the back. (ther is no frount or back to the base)
The only thing that dertmans the frount or back, is which side the cable comes out.
Once the topper is in the base.
Plug in a battery, or Usb power…
Once pluged in you can then turn on with the middle switch.
The swich also changes the colour. + and – change brightness.
If the topper needs to be held in place, there are pegs supplied to help.
Other pegs can be used to hold the cable in place.
