INTRODUCTION

When an error occurs, the terminal displays an error message at the bottom of the screen, on
lines 25 and 26. Some errors indicate wrong keyboard input. Others indicate improper config-
uration settings. A few signal a terminal malfunction.
ERROR MESSAGES
The terminal generates several kinds of status checks and diagnostic error messages. You
should concern yourself with two: user-error messages and system error messages.
Most user error messages occur when you enter data that the terminal was not expecting or
request a service that the terminal cannot perform. However, some errors result from incom-
patible settings in the configuration menus.
System error messages may indicate the integral printer is malfunctioning (see Appendix C
if this option applies to your terminal) or that the battery protecting non-volatile memory
has failed (see appropriate paragraphs in Section 11).
Error messages appear on lines 25 and 26, replacing the function key labels. Pressing the
1:1
key clears the error message, restores the labels, and unlocks the keyboard.
Table 10-1 lists the error messages and their meanings.
