Desaturation requiring times greater than 24 hours will display 24 (or 23:50)*. until the
time decreases to the maximum the display will allow depending on the configuration of
the model Dive computer being used.
Generally, the Desat countdown will reach 0:00 prior to the Fly countdown reaching 0:00.
In the event that Desat Time still remains at the end of 24 hours, when Time to Fly becomes
0:00, the unit will shut off and any remaining Desat time will be cleared.
*We do not go beyond 24 hours since there is not a realistic set of repetitive dive profiles on
SCUBA for which the 480 minute tissue exceeds 8 FSW, which clears at 24 hours. All other tis-
sues with a half time of 160 minutes or less will have desaturated in less than 12 hours.
MAINTENANCE AND SERVICE
A dive computer must be protected from shock, excessive thermal conditions, chemical
attack, and tampering. The housing, made of an impact resistant resin, is extremely
shock resistant but susceptible to chemical attack and scratches. Protect the lens against
scratches with an AERIS Instrument Lens Protector. Small scratches will naturally disappear
underwater.
Operating Temperature
AERIS dive computers will operate in environments having air temperatures of 20 to 140°F
(- 6 to 60°C) and water temperatures of 28 to 95°F (- 2 to 35°C). It is possible to damage
the electronics if left exposed to intense direct sunlight, or in a hot confined space (like a
car trunk). After the dive, cover the dive computer and keep it out of the hot sun.
