TCG Control
This function is optimized for high power-output sonar system. It could help the sonar
work properly in a noisily environment.
In order to control the surface noise and self-ring of transducer, the sensitivity is
automatically changed in different depth. The diagram below shows the sensitivity
changes according to depth.
Note:
from the diagram, we can see the TCG function only control the signal between
0~5 meters. So, if the enviroment is noisy, and you wish to see the underwater condition
in the shallower layer near 0~5m, please set the TCG Control as “On”.
Note:
In air, the signal consumption is much bigger than in water. So, if you try to
test the sonar sensitivity in the air, please set theTCG Control as “Off”.
