Troubleshooting
12
As a first step in resolving problems, consider the
points in this section.
General
•
As soon as an error occurs, stop what you are
doing. Write down what the system is doing and
what actions you took immediately before the
problem occurred.
•
Make sure all devices (printer, laser scanner, etc.)
are connected firmly to the PTC and are turned on.
•
If any messages display on the screen, look them
up in your software manuals.
•
Does the Power LED glow? Does it stay on or blink?
•
Has the beeper sounded? How many times and in
what pattern? Do the beeps seem related to
anything you are doing?
•
Confirm that the PTC has been set up properly.
•
If you are using more than one external device,
disconnect all devices and reconnect them one at a
time. Retest the PTC after you connect each device.
Follow the instructions on page 46 .
•
If the PTC locks up (stops responding to the
keyboard), perform a warm reboot.
