SECTION VI TROUBLESHOOTING
2005 Tech 2 User’s Guide VI - 5
The Automated Main PCB portion tests the following components:
• RAM / ROM
• RS-485 loopback (This test requires the connection of a loopback adapter to the Tech 2.)
• RS-232 loopback (This test requires the connection of a loopback adapter to the Tech 2.)
• Keypad
• PCMCIA slot 1
• PCMCIA slot 2
• Display controller
• Sound transducer
• Real-time clock
Refer to figures VI-9 and VI-10 (next page) for help in diagnosing problems that involve the PCB and VCI.
If the Tech 2 passes all Automated Main PCB and VCI tests, you will not need to run any more tests to
verify that the Tech 2 is working properly.
The following test results will be displayed:
Total Pass................................1 - indicates that Tech 2 passed test
0 - indicates a test failure
Total Failures ...........................0 - indicates that Tech 2 passed test
1 - indicates a test failure
PCMCIA Cards Present...........1 or 2 indicates how many cards present in Tech 2
Once tests are complete, select the soft keys Main Details or VCI Details (Figure VI-6) to review the
results of the main PCB or VCI tests (Figure VI-7 and Figure VI-8).
If any failures occur, select F3: Selectable Main PCB (Figure VI-13) or F4: Selectable VCI (Figure VI-15)
from the Self Test main menu to further isolate the failure. Report failure information to Customer Support.
