Details
Inactive
Select this option to pause the operation. Neither transmission nor reception takes place. When the SN90 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 SN90 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 SN90 system is not able to operate normally. Neither transmission nor reception takes place. For this reason, the SN90 system is inactive during playback.
Replay File
The Replay File dialog box allows you to choose the echo data file(s) you wish to play back.
