if the noise does not go over a set threshold. The interval
is 2 minutes.
This function is useful especially when you have a recor-
ding station, and you are not listening to the unit directly.
It will save you hours of silent recording.

You need to activate VOX before, if you don’t, the unit will
not wake up, even when there is a noise.
Else the unit is in Ultra Sleep Mode, when it will wake up

wake up. If you wish to turn this function off, you have to
send SLP0 to the unit.
