4.7 Remaining bottom time RBT (only with transmitter)
RBT is the time left at the current depth until the point of time when the ascent must be started. The RBT
is shown in the lower display in figures (minutes). The RBT is calculated on the basis of the current tank
pressure, the temperature and the dive data so far registered. The RBT is based on the assumption that
the tank pressure should amount to at least 40 bar at the end of the dive. Alterations are possible
(see page 74).
Ensure that you have enough Air for the Ascent. Do not use the RBT to the
limit if prolonged ascents or an increased rate of breathing (currents…) are
expected.
