6.5 Recording
When considering your recording configurations note that the built-in microphone operates only in
mono mode. The choice of recording file type will affect both the quality of the recording and the
size of the recorded file. If you increase the quality of the recording, it will produce a larger

6.5.1 Built-in Microphone File Type
For the built-in microphone (which records only in mono mode) use keys 4 or 6 to choose to record
in one of:
MP3 64 kilo bits per second (kbps) medium quality
MP3 96kbps good quality
