I can't import an audio file that has 1 hour and 36 minutes.First, make sure that you have enough space on your device and the files you want to add are supported by the player. If there is enough space, I suggest you format the device because there seems to be a malware file that blocks the transfer. You should find the formatting steps in the player brochure, but basically you need to press X once and to use the >> and << keys to select the FORMAT option. If the problem is not solved, navigate to RCA Downloads page, select your device model and download and install the latest version of RCA Digital Voice Manager.
RCA Digital Voice Manager allow the user to efficiently manage their digital voice files. These features include audio playback, audio file enhancement and normalization for better playback quality. Furthermore these files can be easily transcribed into text in a few clicks, through the RCA-Verbalink Interface. The audio files can also be shared with others via our email interface.
