Problem Isolation
In the event of a suspected functional problem, use the troubleshooting
references provided in this chapter. This useful information will help you
to identify and resolve the cause of the problem.
The scanner/scale has a number of features that indicate when a scanner or
scale problem occurs. The unit may:
• emit a series of tones
• light the 7-segment (FRU status) display
• flash one or more LEDs
• display error codes on the Remote Display (if installed)
Three error reporting modes are used: Power-Up Selftest, Operational
tests and Diagnostic tests. These test sequences are explained on the fol-
lowing pages.
Power-Up Selftest
The Power-up Selftest is a pre-operational series of tests that must be suc-
cessfully completed before the scanner indicates readiness for operation.
This pre-operational period is the time between power-up and normal
operation during which the motor comes up-to-speed and software, firm-
ware and hardware are being tested. These tests ensure that all subsystems
are fully functional before turning on the Visible Laser Diode (VLD).

this and other scanner and scale modes.
