Settings - Data Collection The icListen hydrophone can record acoustic data in two formats, Waveform (.wav) and Spectrum FFT (.txt) and has an internal memory for data storage. Lucy can also be used to record data on a computer. - Page 18 User Guide Max Waveform Frequency & Spectrum Frequency The Max Frequency drop down menus provide the options for data collection sampling rates. Max Frequency refers to the bandwidth of the recording, giving the highest frequency that is recorded by the hydrophone at each sampling rate. The sampling rate is given in kilosamples per second (kS/s).

- Page 20 22). Enable Advanced Settings Provides additional settings for Data Collection. Ocean Sonics recommends that users do not change these settings unless very specific requirements need to be met. Waveform Data Format allows the the number of bits used to capture each sample to be changed to 16 or 32 from the default 24.
- Page 21 User Guide Settings - Epoch The icListen can be configured to detect specific signals in real-time data. Five independent triggers can be set, each with a unique trigger signal and unique actions based on that signal. These actions can include recording waveform data, recording spectrum FFT data, sending messages over an epoch channel, or simply logging the event in a text file (EpochLog.txt).
- Page 22 GPS to synchronize all units. Wake from Standby The icListen can be set to wake from Standby mode using the shorting plug supplied with each device. This eliminates the need to apply external power and can reduce battery power usage between setup and deployment.
- Page 23 User Guide Settings - Network This page provides details on the network settings of your hydrophone and allows you to configure how an IP address is set. The default Address Type defaults to DHCP which means that the hydrophone is obtaining an IP address automatically from a DHCP server on the network - usually a Launch Box or a router.

Page 27: Deployment Considerations
Rope Deployment Line When lowering the icListen over the side of a dock or a vessel, a rope should be attached to the hydrophone to avoid placing stress on the connector and prevent equipment loss. A rope can be tied around the body of the hydrophone with secured hitch knots e.g., clove or constrictor. - Page 28 Ensure all equipment is fully charged and working before going out for field deployments. Practicing setting up the icListen with any other equipment (such as a laptop) before the deployment will minimize issues, reduce setup time and ensures that recording is working correctly.
