NOTE:
Before using the unit, ensure that the transducer is clean and free
of debris or oils. If cleaning is required, wash with soap or detergent.
Never allow lubricants, including the provided O-ring lubricant, to come
into contact with the transducer, as this will greatly inhibit performance.
3.2.3 Transponder Checks
Operate the unit in air prior to deployment. In the responder mode, the transducer can be felt to "click"
each time it is triggered. A BATS topside can be used to test the 4380.
To test transponder mode:
1. Send an acoustic signal out of the BATS hydrophone. (The BATS interrogation frequency should
match the 4380 interrogation frequency as outlined in the start-up parameters)
If you do not have a BATS or BATS hydrophone, then a transmitter capable of outputting a 5ms
CW pulse can be used. (Once again, the user will need to make sure that the frequency of the
pulse matches the 4380 Interrogation Frequency)
2. The 4380 will receive the transmitters signal; wait the user-determined Turn-around Time; and
then send out an acoustic reply. Depending on the tester, the user may hear a click from the
