If in case of silence, the recorder does not go to
Signal Standby Mode and continues recording,
VAS level is to be changed to be closer to zero (if it
was -20 dB, now it should be set at -17 dB).
If when desired signal appears the recorder
does not go to Record Mode, the level of VAS
should be changed to be closer to -55 dB (if it
was - 20 dB, now you need to set it at - 25 dB).
VAS time is adjusted from 1 to 15 seconds. If you
set VAS time at 1 second, the record within the file
will be divided into many pieces with the pauses
in conversation for more than 1 second. If you set
15 seconds, after any knocking the recorder will
continue recording silence for 15 seconds. The
best of VAS is achieved experimentally, but for
most cases the value of 7 seconds is enough.
If VAS operates together with timers, you don't
have to enable recording as it starts automatically
with the timer, providing that you synchronized
the recorder's time with the time on the PC.
Circular Recording
The Recorder has the option of circular recording.
In the EMPlus program you can devote a part of
the recorder's memory (or the whole memory)
