To view the Support Page or the Owner's Manual with Operating Instructions just use your mouse to click on the link, which is the underlined and highlighted text just above. This will open a new web browser page automatically for you and allow you to view the information at the website indicated or the contents of the Owner's Manual.
You may need ADOBE READER installed on your computer to read PDF documents. You can download this free at WWW.ADOBE.COM if necessary. Click on the DOWNLOAD ADOBE READER button on right side of the ADOBE home page when you get there, and then just follow the onscreen instructions to install it.
First try the following process to restore your unit:
Power off the unit.
HOLD down the power button and you will see "Pre Boot Mode" appear on the lower part of the display.
KEEP HOLDING the power button down and the display will flicker, keep holding until the pre boot mode message disappears.
This seems to take a long time (60 seconds at least).
Once the pre boot mode message disappears, release the power button and your device will perform some activites to recover from the above problem.
If that procedure does not workfor your unit, then try the process titled M3 - Recovery Process # 2, described in detail in the FAQ section at the following link:
Please comment back here to this page if you have any questions, have difficulty accessing the links, or just require further general assistance and I will respond as soon as I see it.
Thank you very much and good luck.
