About this manual
The purpose of this publication is to provide the descriptions, procedures and detailed
parameter explanations required to allow for safe and efficient use of the FM90i system.
The publication also provides you with a thorough understanding of the parameters and
adjustments provided by the FM90i system.
Note
This manual does not provide any information related to the operation of the Simrad
FX catch-monitoring system. For such information, refer to the relevant FX end-user
documentation.
Target audience
This publication is intended for all users of the FM90i software. Due to the nature of the
descriptions and the level of detail provided by this publication, it is well suited for those
who are - or wish to be - expert users.
A good understanding of system functions and controls is essential to fully take advantage
of the functionality provided. Sea conditions vary, sometimes drastically. The acoustic
conditions are also changing. Temperature and salinity layers differ from one day to the
next, and from one position to another. It is not possible to identify settings that will
provide the best data at all times. A careful study of the information in this manual is highly
recommended, preferably while exploring the functionality offered by the FM90i system.
We assume that you are familiar with the basic acoustic principles of sound in water. We
also expect that you have some experience with sonar operation.
License information
