Please help! We are customers (Southern Co) and we need a manual DX4500DX4600 C2699M-B (7/09) which seems to be discontinued, but we have a Digital Video Recorder and need the manual.
You can download the manual for the user guide from the link posted below. It's in PDF format which means that you will need a PDF reader in order to open it.
Here are some PDF readers that you can install on your PC in order to open the file: http://software.informer.com/search/pdf+readers
