•	Connect the Psion with a PC and use Rcom or Psiwin to transfer the files to the Psion. 
•	Copy the main program Film30.opa in an \APP directory on the internal disk or on a SSD card.
•	Create a directory called \APP\FILMCALC\ on the same disk or SSD card and place the file  Sysdat.002 and all files with *.OVL ,*.DBF and *.FON in that directory.
•	Install the program from the system screen via the Applications menu or  with Psion-I.

Important!!! The name of the owner should be entered in the system screen  / info / owner menu before using the program! Afterwards changing this name will make your registration invalid.

USING THE PROGRAM:
The program has help lines at the bottom and right side of the screens.
In the mainscreen press the "Menu" key to open the menus, select a calculation with the "Arrow"  keys and press "Enter". Version 3.0 has some new keys in the result calculation screens but the older keys (spacebar for recalculation and Esc for back to main menu) are still functioning.
