To remove the frame, simply grasp from both sides and slightly lift up and out to remove it from the backplane.
Once your Vestaboard is securely mounted, carefully lift the frame and place it gently over the top of the backplane. Allow it to hang in place and don't be concerned if you don't hear a click. The force of gravity will ensure that the frame stays firmly in position.
The frame must be properly placed over the backplane before powering on your Vestaboard. If pairing for the first time, note that your Vestaboard's unique pairing code will not appear if the mask is not properly in place.
