The frame must be properly placed over the backplane before powering on your Vestaboard. If unboxing and pairing for the first time, note that your Vestaboard's unique pairing code will not appear if the mask is not properly in place.
After your Vestaboard backplane is securely mounted and installed, pick up the mask frame and gently place it over the top of the backplane to allow it to hang in place. Do not worry if you do not hear a click, as gravity alone will keep the frame firmly in place.
To remove the mask frame, simply grasp from both sides and slightly lift up and out to remove the frame from the backplane. Please be careful when lifting as to not damage the Bits.
