Hi Mustafa
I have not used Fuji 400 H but do use ILFORD HP5 Plus in cameras with the red windows. ILFORD print the numbers and warning rings quite faintly so they do not burn through onto the emulsion and very effective that proves to be. However, it is an easy matter to either tape over the window after each winding on or to make a simple cover out of Velcro. Like in here:

What you see in the window with ILFORD films is as follows:
After engaging the paper leader in the take-up spool and winding on sufficiently to be sure the paper is pulling long from the loaded spool, simply close and lock the back.
Wind on and you will see a thick black line go past the window, keep winding.
Next you will see a series of boldly printed black arrows, keep winding.
Next you will see a small ring faintly printed
Then a second bigger
Then a third bigger still
Then a fourth even bigger
Immediately followed by the frame number, whereupon you stop winding when the number is centrally positioned in the window.
After exposure simply wind on repeating the sequence from the small ring stage above.
