How much dictation recording time is available in the DM-520?
The amount of potential dictation recording time available in the DM-520 depends on
several factors, including the selected quality mode and whether the recorder is
configured to use internal memory or a removable memory card (sold separately).
When a quality mode is selected, several audio file properties are put
into place. These
properties determine the level of detail of the saved file data. A higher-quality recording
saves more-detailed information and creates a larger data file that uses more memory.
A lower-quality recording makes a less-detailed data file, so the memory lasts longer.
Podcasts and Audible files use up portions of the recorder’s built-in flash memory, as do
files saved on the recorder when it is used as a USB flash drive (aka “thumb drive”).
This usage will reduce the amount of memory available for recording new files.
The table below shows the maximum dictation recording times possible using the built-in
memory (assuming there are no other files saved in the re
corder).
