transducer is properly installed without unintentional skew, this angle can be
set to 0 degrees.
b
Rotation Around Y
: Specify an angle (in degrees) to compensate for any deviation
from the Y axis (athwartship direction) in the vessel coordinate system. If the
transducer is properly installed without unintentional skew, this angle can be
set to 0 degrees.
c
Rotation Around Z
: Specify an angle (in degrees) to compensate for any deviation
from the Z axis (vertical direction) in the vessel coordinate system. This is the
alignment angle.
• If the 0° transducer mark points to the starboard (right) side of the vessel’s
centre line, insert the alignment as a number between 0 and +180 degrees.
• If the 0° transducer mark points to the port (left) side of the vessel’s centre
line (as shown in the illustration), insert the alignment as a number between 0
and –180 degrees.
Examples:
• If the alignment angle is 120 degrees on the port side, insert -120 degrees.
• If the alignment angle is 15 degrees on the starboard side, insert 15 degrees.

Inserting the installation parameters for the motion reference
unit (MRU)
The physical rotation of the motion reference unit (MRU) relative to the transducer is
required to allow the MF90 system to adjust for roll and pitch as accurately as possible. This
task is only applicable is you are using an external motion reference unit on your MF90
system. Correct values for motion sensor rotation are critical for the sonar performance.
Prerequisites
The MF90 system hardware units are installed as specified in this manual.
• The MF90 system is turned on and operates normally.
• The MF90 system is in Normal mode, but
TX Power
is set to Off to prevent transmissions.
