Inactive
Select this option to pause the operation. Neither transmission nor reception takes
place. When the ST90 system is disabled with this function, it will stop. The current
echoes are removed from the display presentation.
Normal
Select this option to start normal operation. The ST90 system will transmit ("ping")
the acoustic pulses into the water and receive the resulting echoes. The information
is processed by the Processor Unit, and the resulting data are shown in the display
presentation.
Replay
This mode allows you to play back previously recorded data. In Replay mode the
ST90 system is not able to operate normally. Neither transmission nor reception takes
place. For this reason, the ST90 system is inactive during playback.
