The SoundTrap ST500 is powered by up to 9
‘
D
’
cell alkaline batteries. These are loaded in sets of 3,
meaning the recorder can be deployed with 3, 6 or 9 batteries depending on desired length of
deployment.
We strongly recommend only using Energizer batteries.
These are commonly available and all
testing and advertised battery endurances have been based on this brand. Performance of other
brands is unknown. Most importantly, Energizers are guaranteed not to leak electrolyte when left in
a discharged state. Other battery brands may leak, potentially causing damage to the electronics.
Where possible we recommend checking the voltage of each cell with a multi-meter, prior to
inserting into the recorder. Checking each cell will avoid the possibility of a bad (low voltage) cell. A
single bad cell can significantly affect the recorder endurance and potentially cause damage through
leaking electrolyte. Each cell should have a voltage of at least 1.5V.
Be careful to ensure correct battery polarity as indicated by the diagram in the battery
compartment. Once loaded, double check each batter
y’s
polarity.
Just one reversed battery is
enough to severely impact the overall battery life, and potentially cause damage through leaking
electrolyte. Always double check each cell
’s
polarity.
It is then very important that you verify the supply of power to the electronics. To do this press the
‘BAT’ button on the IR remote and observ
e
the SoundTrap’s red status LED. If all is well you should
see two long red flashes. Note that there is a 10 second delay between connecting the batteries and
the software determining that the supply is stable. Observation of the two long flashes is
confirmation that at least one set of batteries are correctly installed and ready to go.
A single short red flash indicates a problem. In this event, inspect the batteries for correct insertion
and adequate battery condition.

Installing the hydrophone
From the factory you’ll
find the (removable) hydrophone stored inside the battery compartment for
shipping. Unpack and plug it into the wet socket in the recorder endcap, then secure with the locking
collar. The hydrophone is the most fragile component of the system, so best remove it during
transport, and take care to avoid impacts or crushing during deployment.

Install the SoundTrap host on your PC
To start
using your SoundTrap you’ll need to install the SoundTrap Host software.
