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.
