GENERAL DESCRIPTION
The 2405 Acoustic Receiver system is a standalone, battery powered, acoustic receiver
system, tuneable to all frequencies between 8 kHz and 50 kHz which can be used by an ROV
for tracking and locating underwater acoustic transmitters. The system consists of a 2405 unit
and 2401 directional hydrophone.
Acoustic signals are displayed as they are received by the 2405 unit on a 2.7” graphical
display and three high brightness LEDs positioned below the display. The 2405 system
requires no interface other than an ROV camera to observe the received signals on the display.
The user can turn the unit ON and OFF as well as modify several settings using a single control
button and intuitive menu system on the 2405 unit.
The directional sensitivity of the 2401 hydrophone allows the operator to locate acoustic
transmitters by observing the signal level received and the relative orientation of the 2401
hydrophone.
