11. Recording by Timer
Timers are enabled and configured via configuration file (CONFIG.INI). If at least one of the timers is on,
the Recorder switches to record mode automatically from the off state, i.e. the Switch is in OFF position.
Regardless of the timer setting, recording can be enabled manually, by shifting the Switch from OFF to
ON. Recording enabled manually is continuously in progress, timer settings not affecting it.
To activate the timer (s) after setting, enable it by changing “N” to “Y”.
When starting a timer recording, the indication is similar to the one of regular Record mode.
IMPORTANT! In order to prevent errors, avoid overlapping of timers within each other.
12. Recording by Sound Level
Recording by sound level can be activated and adjusted via configuration file (CONFIG.INI). If the
function of sound level recording is on, then when switching to record mode, the Recorder does not
start recording immediately, but needs to check sound level. After the sound appears, the Recorder
starts recording. If there is no sound for the time set in the settings, the Recorder stops recording.
Sound check can be continuous, or periodical. During periodic testing, current consumption is reduced,
but sounds that fall between the checks are not recorded. During recording, the Recorder checks sound
level continuously, regardless of check regularity configured.
After setting, do not forget to enable its operation, by changing “N” to “Y”.
While checking sound level, there is a dim red LED on, and when the threshold is exceeded, the
Recorder indicates operation the same way as during regular recording.
13. Recording by Timer and Sound Level
The use of timers is described in Section 10. The use of sound level recording is described in section 11.
If you use both functions at the same time (recording by timer and sound level), when the timer is
activated, the Recorder switches to sound level check mode, and remains so for the whole timer period.
The Recorder starts recording as any sound is registered, and stops when there is no sound.
14. Recording using AGC*
The Recorder provides the option to use AGC (automatic gain control). AGC system provides automatic
increase of signal amplification in case of silent sound, and attenuation of the recorded signal with very
loud sound, which avoids large distortions (overloads) in the recording.
Attention! This effect is also achieved by processing the record.
* AGC function is available only for the recorders of the CARD16 series
