The toilet I have requires the push buttons to be removed to enable the cistern cover to be removed. The push buttons can be removed by attaching a piece of sticky tape to the button and lifting it out. The screw attachment under the buttons can then be accessed.

The centre button should unscrew(anti clockwise)it's only finger tight.

I can answer this question...
How do I remove the cistern cover that has a push button operated flush?
