Troubleshooting

The highest level of the RAE–2 PDA troubleshooting diagram is shown in
the following figure.  All the diagrams are made assuming that there is no
visible faults, such as short–circuits or loose pins, on the PDA.

The module check begins with connecting the supply voltage to the PDA.
If the current consumption differs a great deal from the normal limits, it is
good to proceed to the Power–On check.

During BIOS detects some error during POST it tries to beep the buzzer
for further fault analysis for the user.  The POST beep codes, number of
beeps are in the Appendix A on p.54.

If the current consumption is OK,  it can be tried if the wintesla service
software is able to get connection to the PDA.  If the target PDA does not
respond to the pings from the host, it is good to check the Power–On pro-
cedure.

When the PDA responds to the wintesla, further peripheral tests may be
carried out. The execution order is not significant and it may be freely
changed. Along with the actual tests, wintesla offers advanced methods
for isolating the possible cause of the fault.

After all the functional tests are working, the device under test should be
re–booted, and the normal usability of the GEOS, along with the CMT
module should be checked before the PDA can be considered to be fully
functional.
