The case has a pressure relief vent to allow any pressure build-up in the case to release before the case is opened. A manufacture’s tag is attached to the vent and should not be removed. Removing the tag may damage the vent.

  • Page 11: Connectors And Caps

    1.5 Connectors and Caps There are four bulkhead connectors on the right side of the VR100 case that are used to connect the different components of the VR100 system to the receiver, such as the hydrophone. The picture below shows the connectors without their protective caps in place.
