NOTE:The dive computer can estimate volumetric surface air consumption (SAC) or respiratory minute volume (RMV) only if the air volume of the tank is entered in the dive computer (Transceiver Settings). The dive computer can estimate pressure-based surface air consumption (PSAC) with or without the air volume of the tank.
