4.7 Switching the recording on/off
After correct configuration you can trigger recording by pressing the START button. Recording in-
progress is signalled by icon on the top bar and flashing red LED.
To stop recording, press the START button and confirm your intention to stop in the pop-up window.
Stopping the recording will be confirmed by sounds (three long and three short signals) and the col-
our of the recording icon will change into , and the red LED will stop flashing.
Recording ends automatically when the memory card is full, recording terminates au-
tomatically.
4.7.1 Approximate recording times
The maximum recording time depends on several factors, such as:
 memory card capacity,
 averaging time,
 network type,
A few selected configurations are given in Tab. 4.2. The last column specifies the approximate record-
ing times when the memory card is almost completely empty and has approx. 3.6 GB of free space. If
the averaging time is different than the one chosen for the sample user configuration of 1 second, the
approximate time of recording is proportionally extended, e.g. for 10-second averaging, the recording
time will be 10 times the specified recording time at 1-second averaging.
