Camera modes of operation

STV0680B + VV6444/6410/6500

18/63

Version 3.4

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.

3.3.3

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.

3.3.4

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.

3.3.5

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.
