First of all, here is the direct link to the ONLINE USER'S MANUAL for that model:
http://www.novisec.nl/cms/component/option,com_docman/task,doc_view/gid,67/
To view 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 and 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.
See page 17 of the ONLINE USER'S MANUAL for detailed instructions on how to reset the unit to default settings. Basically it says:
Push the MENU button, select admin and enter 3477 for the password, then press OK to confirm.
Use the arrow keys to navigate to UTILITIES, then press ENTER.
Then navigate to RESTOREPARA and press ENTER.
Then select OK to confirm and the system will automatically reboot.
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.
Joe.
