It came with a USB management cable, if you attach the cable to your PC from the device you can then run the management software and change the alert settings. I believe it came with the management software as well, but the manufacturer's site should have the latest version if you can't find that. The management cable that came with it is just a standard USB "A to B" style cable, if I'm not mistaken. That's in case you can't find the one that came with the device.
