Error Recovery and Troubleshooting
Troubleshooting Guide
Table 7-2 lists some minor problems, causes, and actions to take. If you cannot resolve the
problem after checking this list, call the Symbol Support Center for assistance.
Startup Failure
Problems are most frequently start-up failures. If cold booting the terminal does not start the
application successfully, either the application, the system software, or the system is
malfunctioning. If you can boot the system to Command Mode, try the following:
t Use Program Loader to download a new version of the software to NVM. This
procedure is described in
Chapter 3, Batch and Spectrum One Terminal Setup . After
downloading new software, warm boot the terminal as described in Chapter 5,
Operating the Series 68XX .
t Use Self Test to check whether system hardware is operational. The Self Test
procedure is described later in this chapter.
Boot Failure Messages
During a cold boot, the system briefly displays a status line for each driver as it loads, in the
format
0:Driver #.##
The line shows a status value, usually 0, followed by the name and version number of the
driver. If the system halts at one of these lines and displays a status value other than 0, the
displayed driver did not load properly.
