I have multiple Sat receivers using different addresses and multiple Panasonic disc players using different addresses. These alternate addresses are not in the CCP database, so I have to teach. And so I use the default codeset as a template, is there a way to erase ALL preset commands at once for given device, or do I have to erase each command one at a time? Same for taught commands, can they be erase by device or one at a time? This on mx-780/x-7.
