We recently had  a PVR replaced with the Motorola DCX-3400 M model. We noticed two flashing arrows on the front of it which have flashing since day one of the install. I also noticed a low level chugging sound  and that too has been ongoing since we replaced our previous PVR. Is this a technical issue one should be concerned with?
