5. Use the UP or DOWN arrows to display other options in place of Self Test. When the
option you want appears, press ENTER to select it.
If warm or cold booting do not clear your problem, but you can boot to Command Mode,
the problem may be:
!
BIOS and hardware problems: to check the BIOS and hardware, use the Self Test
function to check the system hardware (described on page A-2). If there is a
hardware problem, contact Symbol Technical Support.
!
Application program error: if system hardware is running properly, check for an
application error. Perform a Memory Transfer (described on page 6-8) so that a
programmer can perform application-specific troubleshooting. Then install the
correct version of the software as described on page 4-2.
If Rebooting Fails
1. Re-install software following the procedures described in Chapter 4, Installing
Software.
2. Contact your authorized Symbol Support representative or Technical Support
Services.
