ERROR CODES SUMMARY
As part of the terminal's power on sequence, it performs an internal self-
test, and signals that it has successfully completed this test by sounding the
audible alarm. However, if a non-fatal error is detected, an error code will
be displayed'on the screen. For example, if the letter "0" is displayed, this
signifies that a fault has been isolated to the Power/Logic PCB (i.e. IC
Ul8). The following table lists all possible error codes.
