Detailed Features

2.2.4

Piezo buzzer

An on-chip pulse width modulator (PWM) generates buzzer sounds to signal certain events. The

distinctive sounds are characteristic of the type of events indicated by the buzzer, as described here

below.

1 Camera has been ‘Woken up’ from standby mode (either by the user pressing a button, by re-

connecting the power source, or by connecting a USB/RS232 connection).

2 Camera has ‘gone to sleep’ that is moved into standby mode. Pictures are retained in memory.

3 Picture was taken successfully once the user had pressed the capture button.

4 Picture has NOT been taken when the user pressed the capture button because of insufficient

light, or because the exposure control was not ready following a rapid change of lighting in the

scene.

5 Picture has NOT been taken when the user pressed the capture button because the picture

counter had reached the maximum number of images. The user has the chance to reset the

counter if desired.

6 End of continuous capture in un-tethered ‘Continuous’ mode due to full memory.

7 Self-timer activated, count down has started.
