Hello, 1. What is the # of the backup battery on the CDD-48A Memory Card? 2. How do you rewire the power input from 230 VAC, to 115 VAC? 3. What is the correct value of the fuse for 115 VAC? 4. Does anyone have a NRD-505 manual they would sell, copy, or loan me? Or is there a downloadable copy of one somewhere? Thank you, Bruce WA8TNC
