There are two separate issues here.
Your calculator is in Algebraic mode. To switch to RPN, press MODE 5 .
Your calculator is also in Octal mode. To switch to Decimal, press right-shift 1 1 .

SOURCE: my calculator has a funny format
Try pushing and releasing [f], then . This will give you 4 decimal places. (It follows that if you want 5 decimal places, push 5 instead of 4, etc). If that doesn't work, you can try taking the batteries out and putting them back in which should reset it to 2 decimal places, then set it where you want it following the above.
If it continues to malfunction I suggest taking the batteries out for 24 hours to allow a static discharge. This will lose anything you stored in the calculator, setting it back to how it came from the factory.

do a self test
1. Turn the calculator on.
2. If you have the optional infrared printer, turn it on. Certain diagnostic
information is printed during the test.
3. If possible, return to the MAIN menu (press @A).
4. To start the self-test, hold down C while you press the fifth menu
key from the left. Once the self-test has begun, do not press any keys
until you are ready to halt the test.
5. During the test, the calculator beeps periodically and displays various
patterns and characters. Watch for one of two messages that are
displayed before the test automatically repeats:
If the calculator passes the self-test, the calculator displays
If the calculator displays followed by a five-digit number,
the calculator requires service.
6. To halt the self-test, hold down C while you press the third menu
key from the left. The calculator displays . If you
press any other key instead, the test halts and the calculator displays
a message. This results from an incorrect key being pressed,
and does not mean that the calculator requires service.
7. If the calculator failed the self-test, repeat steps 4 through 6 to verify
the results. If you do not have a printer, write down the messages that
are displayed in step 5.

SOURCE: Number 6 on Key Pad, not working
I had the identical problem. One of the fixya folks helped me disassemble the calculator, which I did (there are about 6 plastic rivets which must be reamed away before the circuit board can be lifted out). Be careful not to lose the grounding springs which go back through the two hollow plastic posts. Pull the white sticky covering back carefully, noting which contact represents the "6". Clean the contact area as described but also make sure the contact is in the dead center of the "cut outs" in the sticky film area. When reassembling, I put a small piece of ace bandage between the board and the back of the calculator (towards the bottom, do not block the metal plate where it contacts the "spongy metal" grounding box). This is needed for support since the rivets have been removed.Carefully reassemble everything including the springs. Mine worked perfectly afterward!
I do have a theory that the magnets used in the "anniversary" case have an adverse effect on the calculator. Just a hunch, since one sits over the "6" key. I don't use that case anymore. Sorry they don't make 'em like they used to!
