NOTE:
- before you start working with the device, become familiar with this user instruction and make sure the
electrical and mechanical systems have been made properly and the correct parameters have been set;
- if the parameters of the transducer have been set using the AR956 programmer, the ARsoft-CFG software
must be configured properly.
A detailed description of the configuration parameters of the transducer can be found in chapter 9.
