Oceanic Customer Service has received several OC1 units that were returned from product owners who experienced similar problems with display of dive mode information. Upon descending on a repetitive dive, while in Watch mode, tank Pressure and calculated information associated with Pressure (such as Air Time Remaining) were missing from the usual dive mode screens. Users may upgrade their OC1’s firmware (operating software program) to newly released revision 1E.04 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.
