end cap and transducer as illustrated (cross-section).
Inspect and fully clean the o-ring grooves.
3. Check that all seals in the bottle are clean and lubricated.

What to do next
You need to set the correct transducer orientation from Mosa2.
Selecting A1 Board Orientation
You need to check the orientation of the A1 board inside the sensor in order to correctly receive
data.
Before you begin
The sensor is connected to Mosa2.
CAUTION: Do not open the sensor to check the A1 board orientation. It can be checked and
configured using Mosa2.
About this task
The transducer (yellow part) can be installed in two different positions, with a different angle
of 90°. When the down sounder points to the ground, the A1 board inside the sensor can be in a
vertical or horizontal position depending on the transducer orientation.
Usually, for V1 versions of sensors, the standard orientation is horizontal and for V2 and V3 it is
vertical. If the selected orientation is not the standard one for your version, this has no effect on
the correct functioning as long as you select the correct orientation.
Procedure
1. Place the sensor with the down sounder (circle or A on transducer) toward the ground.
2. Click the tab Pitch and Roll .
3. From Select Orientation , click Apply .
The orientation is selected according to the A1 board orientation.
