I respected the instructions provided before putting in operation, the galley for use! 2 days for that this duo is charged, contrary to the assertions of the record. copy files based on call? more that random! it unloads very quickly, time to get a few sheets, it must rest on the base. This is however not the first gigaset I bought the best for my use is the S810, I just recommend. This one, I'll send it, what a disappointment!
