Flying or traveling to a higher altitude after a dive may significantly increase
the risk of decompression sickness.
3.5 Personal Adjustment and High Altitude Dives
The
IQ-400
can be adjusted for increasing the conservatism of the mathemati-
cal model or for diving at altitude.

WARNING
YOU ARE ADVISED TO AVOID FLYING ANYTIME
THE COMPUTER DISPLAYS THE DO NOT FLY
WARNING - INDICATED BY AN AIRPLANE!
Further, the Divers Alert Network (DAN) advises as follows:
• A minimum surface interval of 12 hours would be required in
order to be reasonably assured a diver will remain symptom
free upon ascent to altitude in a commercial jetliner (altitude
up to 2400 m [8000 ft]).
• Divers who plan to make daily, multiple dives for several days,
or make dives that require decompression stops, should take
special precautions and wait for an extended interval beyond
12 hours before flight.
TUSA
recommends that flying be avoided until both the DAN
guidelines and the
IQ-400
wait to fly conditions are satisfied.

WARNING
SET THE CORRECT
PERSONAL/ ALTITUDE ADJUSTMENT MODE!
When diving at altitudes greater than 700 m [2300 ft] the per-
sonal/ altitude adjustment feature must be correctly selected in
order for the computer to calculate no-decompression status.
The diver should also use this option to make the calculations
more conservative, whenever it is believed that factors which
tend to increase the possibility of decompression sickness exist.
Failure to properly select the personal/ altitude adjustment
mode correctly will result in erroneous data and can greatly
increase the risk of decompression sickness.
