1: Introduction
The 100 Wh Subsea Power Bank provides a rechargeable underwater power solution for longer
deployments of icListen hydrophones, or other instruments. Previously, autonomous deployments of
the icListen were limited by the 8-hour capacity of the internal battery. Now, paired with the 100 Wh
Subsea Power Bank, deployment durations can be extended by up to 2 days. The Subsea Power Bank
gives users a low cost, compact, and easy to deploy option to integrate with their hydrophone system.

6: icListen Hydrophone Synchronization and Ethernet
The icListen hydrophone synchronization and ethernet signals remain functional as they pass through
the Power Bank. These signals require more power so deployment duration may be reduced.
A: Error Signals and Troubleshooting
The flashing red LED is a general error indicator which could be triggered by several different
circumstances. Please follow these troubleshooting steps when the LED indicator is flashing red:
1. Ensure the Power Adapter and Power Cord are the exact ones provided by Ocean Sonics Ltd.
2. Disconnect the Power Adapter from the Power Bank, wait 10 seconds, reconnect the Power
Adapter.
3. Disconnect instruments when attempting to charge the Power Bank.
4. Ensure the instrument load is not too large. The maximum discharge current is 1.5 A.
5. Ensure the temperature the Power Bank is between 5°C and 35°C.
Contact Ocean Sonics Ltd. if the troubleshooting steps above do not resolve the problem. The Power
Bank may need to be returned to Ocean Sonics Ltd. for servicing.
