In response to input received from staff and users of the Pro Plus 3, Oceanic has corrected or modified the following items to improve the Pro Plus 3’s operation dive. Users may upgrade their Pro Plus 3's firmware (operating software program) to newly released revision 1B using the Check for new Firmware Update feature of the latest OceanLog PC interface program. There is no need to return the unit to Oceanic.
Oceanic has received isolated reports of DVT assemblies using a specific batch of DVT plungers extruding. Testing and analysis indicates that this occurs when the First Stage is only partially depressurized prior to the removal from the cylinder. Back pressure from the instrument console could cause the DVT Plunger to extrude.
Oceanic has initiated a mandatory replacement (retrofit) of all original QLR3 Weight Pockets (with black stiffeners) with newly designed Weight Pockets (with gray stiffeners) that afford better locking.
