I'm assuming you're in RPN mode. RCLF isn't about Fourier, it's about
general calc flags (modes). Flag settings can be crucial on how you
see your results. If you hold down ON and hit F3, your 50g will reboot
(DON'T do this yet, it will mess up your fonts!). The screen that then
comes up is what I consider to be the default, or "stack" display. At
this screen, type RCLF and hit Enter (if you're already at the stack
display, and you probably are, you don't need to reboot). Depending on
your font size, you may need to hit VIEW and use the the cursor keys
to see the whole string. RCLF is short for Recall Flags; this is how
your calc remembers all your flag settings. For a more thorough
written explanation of flags, take a look at this:

A month or 2 ago, someone left URLs which led to a couple of great
tutorials for HP 50g for college kids (the 1st of which includes their
recommended flag settings):

If you have time, leave a keystroke by keystroke example of what
you're trying to do, along with your RCLF string.
