beacon. If a click was not heard, place a hand on the transducer head so as to feel the beacon
reply.
To test the transponder:
1. Connect the oscilloscope to a wire wrapped around the 4380 projector transducer or the
4325/4335 remote transducer.
2. Set the oscillator to the proper interrogation frequency and momentarily connect the speaker to
produce an interrogation.
3. Hold the speaker close to the projector transducer. If the transponder replies, the electrical reply
signal will be seen as pick-up on the wire wrapped about the transducer on the 4380 or 4325/4335
Acoustic Projector.
3.2.4 Mounting
The 4380 can be mounted to any suitable structural surface. Care should be taken, however, to isolate
the aluminum pressure case from dissimilar metals, thus preventing electrolysis.
The 4380 can be mounted in any position, but care should be exercised to mount the projector transducer
so that it has a direct acoustic path to the receiving hydrophone when in operation. Mounting of any
transducer can change the beam characteristics of that transducer. It is best to perform a shallow water
test to assure proper operation prior to final deployment.
3.3 Post Deployment
After deployment, clean any fouling from off the transducer with mild soap or detergent and fresh water.
