SUUNTO COBRA User Guide - Manual (Page 16)

WARNING
Always use realistic SAC rates and conservative turn pressures
during dive planning. Overly optimistic or erroneous gas planning
can result in the exhaustion of breathing gas during decompres-
sion or in a cave or a wreck.
WARNING
ENSURE THE WATER RESISTANCE OF THE DEVICE! Moisture
inside the device or battery compartment will seriously damage
the unit. Only an authorized SUUNTO dealer or distributor should
do service activities.
NOTE
It is not possible to change between AIR, NITROX and GAUGE
modes before the instrument has counted down the no-fly time.
There is one exception to this: You can change from AIR to NI-
TROX mode even during the no-fly time.
In GAUGE mode the no-fly time is always 48 hours.
