the Mask and Transmitter may have to be moved to within

The Link will be restored within 4 seconds after the above
conditions are corrected.
DIVE TIME REMAINING (DTR)
One of the most important pieces of information on Oceanic
dive computers is the Dive Time Remaining numeric display. The
DataMask constantly monitors No Decompression status, Oxy-
gen Accumulation, and Air Consumption Rate.
The Dive Time Remaining display (Fig. 57a) will indicate the No
Deco (NDC), O2 (OTR), or Air Time (ATR) Remaining, whichever
Time is the least amount available. The specific Time being
displayed is identified by the NDC or OTR or ATR icons.
