Before Asking for Repair
If you think that a failure occurred, follow the steps below:
1. Check if the power cord and cables to other products are properly connected.
2. See Chapter 1 (5. Troubleshooting). If you find a symptom similar to your problem, take the action as
instructed.
3. Confirm that the required software has been properly installed.
4. Scan for viruses using a commercial Antivirus Software.
If the problem persists after taking the measures above, contact your sales representative. Take notes on LED
indications and the display on the screen at the failure, which will be useful information for the repair.
For repair within the warranty period, be sure to apply with your warranty.
