Stored pictures may be uploaded to a PC at any time, whether or not the camera is full. Plugging the
USB connector into the camera will cause it to reset and issue a double beep but all stored pictures
will remain. When the USB connector is unplugged the camera will go to sleep. When connected to
the PC the camera may still be used in the normal way.
Note: With the flashgun enabled (STV0680B-003 only) the camera will always take a picture,
whether or not there is sufficient light.
Audio record - Ar
This mode is available on STV0680B-003 only, with audio record hardware fitted.
Pressing the shutter button within 5 seconds will cause the camera to start recording for as long as
the shutter button is pressed down. If the shutter button is not pressed within 5 seconds the camera
will revert to normal picture taking mode. Whilst recording, the LCD display flashes ‘Ar’. If the
recording stops because the memory is full, the ‘memory full’ audio tone is sounded and the display
will stop flashing and display ‘00’. The audio data is digitised and stored in SDRAM.
Audio Playback - AP
This mode is available on STV0680B-003 only, with audio playback hardware fitted.
Pressing the shutter button within 5 seconds will cause the camera to play back the most recent
audio recording. If the shutter button is not pressed within 5 seconds the camera will revert to
normal picture taking mode. Whilst playing, the LCD display flashes ‘AP’.
Once in Audio Playback mode, repeated presses of the shutter button will step the camera through
each of the audio recordings in the camera (most recent first). Keeping the shutter button pressed
down will also cycle through the audio recordings. Pressing the mode button during playback will
stop the audio clip.
Note: Minimum audio recording length is set to 0.5 seconds.
Delete last object - dA/dP/dC
This mode is available on STV0680B-003 only, with audio record hardware fitted.
If the last object captured was an audio recording 'dA' (delete audio) will be displayed, if the last
object was an image, then 'dP' (delete picture) will be displayed, or, if the last object was part of a
continuous capture sequence, then 'dC' (delete continuous) will be displayed. If the camera is
empty, the mode will be suppressed. The mode works in the same way as ‘CL’ (Clear All), i.e. once
the mode is selected, pressing the shutter button once will cause the camera to beep and ‘dA’, ‘dP’
or ‘dC’ to start flashing. Pressing the shutter button again within 5 seconds will delete the last audio
clip, picture or continuous capture sequence.
