1.1 Diving Safety
●To ensure safe and proper use, please read the user
manual before using the MISSION2.
●This manual is based on use of the default settings of
the MISSION2.
●Do not use the MISSION2 as your only diving instrument.
A separate depth gauge should be standard equipment
for every diver and is highly recommended. All divers
should conduct detailed Pre-Dive Safety Checks to
include emergency planning, in case of any equipment
failure during your dive. Firmware updates will be
published on the ATMOS support site as they become
available. Check for updates before your dives.
●Diving involves risk. Only trained divers should use the
MISSION2. Dive computers are not a substitute for
training and good judgment. Do not use the MISSION2
on any dive beyond your certification and experience
level. Diving with an incorrect assessment of your ability
and physical condition can result in injury or even death.
●The MISSION2 is designed for recreational diving only.
Do not use the MISSION2 for commercial diving
applications.
●Divers should never ascend faster than 10m/min
(33ft/min). Ascending at a faster rate will negatively
impact your decompression physiology.

Freediving, the No fly time icon will be displayed when freedives
are over 40m.
Because of residual nitrogen in the body, general dive
guidance recommends waiting 24 hours from the last dive
before flying or otherwise ascending to altitudes above 300m /
1,000ft. The MISSION2 utilizes this guidance. However, your
actual dive profiles (e.g., single dive vs. repetitive dives, shallow
vs. deep) may affect the interval actually needed. Please
consult medical resources if flying in under 24 hours or if an
extensive amount of diving has been performed in a short
period.
