You could call the shower doctor, easily googled but if you struggle to get the cover off, you maybe are not competent to try a repair. Power showers are a mix of water and electric circuits and that can be a lethal combination. My shower is t80i and that seems different but you could look for a cross head screw top centre and bottom centre. If you find the screws, BEFORE you undo them, cover the shower tray plug hole or you will drop one and it will vanish. Also turn off the electric power BEFORE you do anything exposing wires. It also makes sense to shut off the water before you undo anything as well, so take care.
