How do I set it to factory default settings? When I want to graph or want to do a zoom fit I get a ERR:SYNTAX 1:quit

Seems unlikely that you get a syntax error for both graphing and Zooming. Probably the error is in the function you are trying to graph.

To reset the RAM,
Press [2nd]MEM][7:Reset][1:All Ram][2:Reset] [ENTER]
Calculator answers with Ram Cleared.
Press [CLEAR] button to erase the above message.

Once Ram is cleared, open the [Y=] function editor and at the Y1= line, enter [X,T, theta, n] key or [ALPHA][X], to draw the simple function Y1=X.
If that works, that means your calculator is OK.
