troubleshooting steps.
Before you begin troubleshooting, verify the following items:

make sure that your computer has met all the pre-installation requirements, review if the
installation procedures are correct, and check if the program or hardware is properly
installed.
- If an error message appears while the program or hardware is in use, write down the
message and follow the on-screen instruction if any. For further details, refer to the docu-
mentation or user manual of the program or hardware.
