Not so smart meter

Had a 2nd generation IHD3 -CAD-PPMID fitted on 27/03/19 and it started to show limited information on 28th total ie usage in £ but I am unable to access the menu function so cannot set a budget, also it won’t swap between fuels or show current usage on the “now” button or light up the instant electricity usage “traffic lights” symbols, it has a good signal strength,so is it faulty ?
