Dive Time Remaining (Dtr) - Aeris Epic Operating Manual

An interruption of the TMT Link may also occur while the PIC is
in an area within 3 to 4 feet (1 meter) of a running Dive Propul-
sion Vehicle. The Link will be restored within 4 seconds after the
Vehicle is shut off or the PIC is moved out of that area. When
using a Strobe, a temporary interruption may occur shortly after
the Strobe flashes. The Link will be restored within 4 seconds.

DIVE TIME REMAINING (DTR)

One of the most important pieces of information on A RIS dive
computers is the Dive Time Remaining numeric display. The
PIC constantly monitors No Decompression status, Oxygen
Accumulation, and Breathing Gas Consumption Rate.
The Dive Time Remaining display (Fig. 78) will indicate the No
Deco, O2, or Air Time, whichever Time is the least amount
available. The specific Time being displayed is identified by the
symbols TIM and NDC (or O2 or AIR).
In the event that Air Time Remaining (ATR) becomes less than
NDC and O2 Time, after 1 minute the Audible Alarm will sound,
the L D will flash, and the Pressure value will flash.
