Audio page is used for voice activated recording. When this option is enabled, recorder is
recording only when it detects sound above selected threshold level. Minimum level means
the highest sensitivity. Delay is specifying the time, for how long recording continues after
this sound level is not detected anymore. Recommended value is 5 seconds or more. When
LED is enabled to flash during recording, it is flashing only when recording is in progress and
not when the recorder is in idle mode waiting for exceeding the selected threshold level. This
mode saves significantly the battery energy resulting much longer time of operation. For
microphone volume control is implemented AGC function. The recorder should be used in
noisy environment or to monitor large rooms, where all silent sounds are required to be
recorded. When AGC checkbox is checked, this function is enabled and recorder
automatically adjust microphone volume according detected sound level. Maximum
microphone volume indicates the maximum volume used by AGC function. When AGC
function is disabled, this selected volume is fixed for all the time.
Recorder is equipped with internal real time clock and recording scheduler. If you want to use
time activated recording, you can choose from 3 options. Daily timer enables recording
