HP 48g Graphing Calculator - Manual (Page 439)

Q: What do three dots (,„) mean at either end of a display line?
A: The three dots (called an ellipsis) indicate that the displayed
object is too long to display on one line. To view undisplayed portions
of the object, use the Q or © cursor keys.
Q: How do I turn off the H A L T annunciator?
A: Press f P R G ) iN)Cn RUH K I L.I..........
Q : The calculator beeps and displays B .a d A r g u m e n t T y p e . What’s
wrong?
A: The objects on the stack aren’t the correct type for the command
you are attempting. For example, executing
e iJ N IT (in the PRG
TYPE menu) with a number in stack levels 1 and 2 causes this error.
Q : The calculator beeps and displays T o o F e w H r g u m e n ts . What’s
wrong?
A: There are fewer arguments on the stack than required by the
command you are attempting. For example, executing with only
one argument or number on the stack causes this error.
Q: I'he calculator beeps and displays a message different from, the two
listed above. How do I find out what’s wrong?
A: Refer to appendix B, “Messages.”
Q: I can’t find some variables that I used earlier. Where did they go?
A: You may have been using the variables in a different directory. If
you can’t remember which directory you were using, you’ll need to
check all the directories in your calculator.
Q: Sometimes my HP f8 seems to pause momentarily during a
calculation. Is anything wrong?
A: Nothing is wrong. The calculator does some system cleanup from
time to time to eliminate temporary objects created from normal
operation. This cleanup process frees memory for current operations.
This happens less often if you make more memory available.
Q: The Equation Library Solver gives me SI units even when I specify
E H G (or mce-versa).
A: The Solver uses and creates global variables. If the variables in
question were created before, then they still exist (until you purge
them). Their unit definitions also still exist. To override the old unit
system, you must either purge the variables before solving, or you
must enter the specific units you want (such as _ t t ) .
