Troubleshooting

							10OmniBook Self-Test
The OmniBook Self-Test provides on-board hardware and firmware diagnostics.  To operate the
self-test, perform the following steps:
1.  Save all files and close all applications:  The OmniBook is reset at the end of the self-test.
2.  Turn the OmniBook OFF.
3.  Press and hold the [Esc] key and press [ON].  You will hear a short three-tone beep.
4.  Self Test will initialize and start.
5.  To run a test:
Highlight the test name and press [ENTER].
Highlight the test name and press [Ctrl][ENTER] to run a longer
and more extensive version of a test--not available for all tests.
The test runs and its results are reported.
6.  To run several tests in a continuous loop:
Highlight one or more using [ space bar ] and press [ENTER].
Each test runs and its results are reported.
Press [Backspace] to stop the loop.
7. To exit the self-test, press [Esc].
Interpretation of test results
A result of “OK” on any test indicates that the test did not find problems while the unit was
operating in its current state.  A “BAD” result indicates that the test found a problem while the
unit was operating in its current state.  A “BAD” result should always be confirmed by running the
test in a loop for several iterations or running the long version of the test.  Further inspection of
the unit to rule out configuration or installation conflicts is necessary prior to diagnosing the unit
as needing repair.
Any test that is halted by [Backspace] is shown as “aborted” and no results are displayed.
The OmniBook will not enter sleep mode while the self-test is executing.
Loop Back Connectors
In order to run the RS232 serial port or parallel port self-test, a loop back connector is needed.
The loop back may be placed on either the OmniBook port or at the end of the corresponding
cable.  This feature is also helpful in diagnosing a defective serial or parallel cable.
Loop back connectors may be purchased or can easily be constructed.  The following illustrations
identify the correct pin-out configurations for the serial and parallel loop back connectors.

							12Troubleshooting Flowchart
The following series of flowcharts is intended as a guide for troubleshooting the OmniBook 300,
425, 430, and 530.  Each technician should still rely on personal experience and supplemental
knowledge when diagnosing a problem.
These tips should be kept in mind when referencing the troubleshooting flowcharts:
· Use the Main Troubleshooting Flowchart to isolate the problem to a particular area.
· Use the additional individual troubleshooting flowcharts to narrow down the problem to a
specific component or item.
· Always use supplemental information resources, including the Product Support Plan, Service
Notes,  and the World Wide Web, to aid in diagnosing problem areas.
