The Echogram Has A Lot Of Interference - Marport CATCH User Manual

• Check that you see Marport Captain icon in the desktop taskbar. If you do not see
it: close, then open Mosa2. The icon should appear in the taskbar.
Note: Marport Captain is a program running in the background. It allows
Mosa2 automatic opening and displays shortcuts to Mosa2 and Scala
applications installed on the computer. It should not be closed.
• If the problem persists, install Mosa2 again.
At the end of step 2 of the configuration wizard, the sensor does not respond. Mosa2
displays a red cross and the Configuration Cable LED is red.
• Check that no other instance of Mosa2 application is already running on the
computer. If this is the case, close both applications, then open only one.
• Or else, connect the sensor to a charger and wait until it is fully charged.
The sensor has been disconnected from Mosa2.
• Check that the Configuration Cable is not connected to a USB hub. The
Configuration Cable must be connected directly to the computer.
• If the computer goes to sleep mode, the sensor may be disconnected. Change the
settings on your computer to increase the time before sleep mode.
• If the problem persists, connect the sensor to a charger and wait until it is fully
charged. Then try again to connect.
Mosa2 displays a critical error message.
• Disconnect both USB connector and three-pin plug. Then, connect again the
Configuration Cable. If the message is still displayed, it means there is an issue
with the sensor's components. Contact Marport support.

The echogram has a lot of interference

There are interference from environmental noise or other equipment such as
echosounders. You need to increase the level of the echogram filter in Scala2.
Important: Increase the level of the echogram filter only if the echogram has a
lot of interference. Be aware that this filter will remove small targets.
