    1. Tony Mutune

      Hello Thanks for reaching out to Dejavu Technologies Limited. The Error 24 in Mercury 130W means your fiscal Memory is full and so needs replacement. There is a procedure followed which include:
      1. Write a request letter to KRA that you need to change your fiscal Memory.
      2. Its not a process because you write and then get a stamp the same day of presentation.
      3. Once you have all the documents then bring your machine to our main workshop in Nairobi, Moi Avenue , Rahimutulla Trust Building Opposite Bazaar Plaza.

  19. When I put the machine on it beeps and displays P End 1. Why?
