Battery Care
Store the unit at 40 – 60% battery charge. To do this remove the power adaptor and wait until the
hydrophone is between 40-60% charge. Put the unit into standby mode and use the power down
tool.
Note: If powered down for more than 3 weeks the icListen will lose the date and time. When
turned on after storage, it is recommended the hydrophone is charged for 24-48 hours to
recharge all components and maintain accurate time keeping and functionality.
