As a sound segment is recorded, it is held briefly in dynamic random access memory (DRAM) in the camera back, and is then moved to the PCMCIA card where it is saved as a sound file. As a result, the card may contain an intermingling of image and sound files.
The camera back alone cannot play the recorded sound; instead, a computer is needed to access and play the sound files.
How to Record Sound
To record sound, ensure that a properly formatted PCMCIA card is in- stalled in the camera back. Hold the camera back approximately six inches from your mouth, press and hold the record button, speak into the microphone, and when finished, release the record button. The center dot of the disk icon on the camera back LCD comes on when sound is being recorded.
Recording
If the shutter release is pressed while the record button is down, audio recording stops until the image has been recorded. If the record button is still down, the system begins to record sound again.
For simplicity there are no controls other than the record button; there is no volume control, and no way to set the recording level.
