1.General
1.1. Diving Safety
● All dive gear will fail. It is not a question of
whether it will fail, but when it will fail.
Additionally, firmware may have unidentified
bugs. Do not use the MISSION ONE dive
computer as your only source of information.
Use a backup computer or tables, and
complete a dive plan before each dive.
● Diving involves risk. Only trained divers should
use the MISSION ONE. Dive computers are not
a substitute for training. Do not use the MISSION
ONE on any dive beyond your certification level.
● The MISSION ONE is designed for recreational
diving. Do not use the MISSION ONE for
commercial diving applications.
● It is assumed that the diver's ascent rate is
10m/min(33ft/min). Ascending significantly faster
than this will impact decompression calculations.
● Please follow the decompression stops advised
by MISSION ONE. Violation will increase the risk
of decompression sickness, which may lead to
serious injury or death.
● The MISSION ONE is a precision instrument.
Take care to protect your computer from
damaging shocks or chemical exposure. Store
your MISSION ONE out of direct sunlight and
avoid exposure to excessive heat or leaving it in
a vehicle exposed to the sun.
● Do not wear your MISSION ONE in hot spring
pools or saunas.
● After each day of diving, rinse the MISSION ONE
thoroughly with fresh water. Do not use
high-pressure sprays to avoid damage to buttons
or sensors. If the device is covered with dirt, soak
it in fresh water. Do not use any solvents or
detergents.
● Please use the Screen Guard included in the
package. Replacement screen guards may be
purchased from an authorized dealer.
