If Things Go Wrong
Whenever you run into problems—either following examples in this
manual or solving your own problems—you can use these hints to get
back on track.
Lesson 38: Error Messages
The HP 48 indicates that it can’t do something by sounding a beep
(if the beeper is enabled) and displaying a error message. A complete
list of these messages and their meanings can be found in Appendix
B of the HP 48G Series User’s Guide. Clear the message by pressing
(or any other key).
Here are the meanings of four of the more common error messages:
Bad Argument Tupe. You tried to do something to or with an object
that isn’t valid for that kind of operation. For example, dividing by a
text string causes this error.
Too Few Araument 2. You tried to do something without supplying
the calculator with enough stack arguments. For example, executing
with only one number on the stack causes this error.
Irmeslid Card Data. The HP 48 cannot read data stored on a
plug-in card you inserted. However, you will also see this message
whenever a RAM card contains ports you've never used. Press
@&D (LIBRARY) (NXT) FIHIT to initialize all available RAM ports. This
does not affect data already stored on the card.
Unde ined Mame, The HP 48 attempted to execute a command that
requires numeric arguments and found a symbolic argument it could
not convert into a number. If the command should accept symbolic
arguments, then perhaps the Numeric Results flag (-3) is set (press
@) (ODEs) FLAG to check). Clear it and try again.
