Personal Adjustment and High
Altitude Diving
If you are diving at higher altitudes, make sure that the altitude mode has been
set according to the altitude of your dive site.
For information on how to select the correct altitude setting and how to use
the personal adjustment, see Section 3.5, “Personal Adjustment and High
Altitude Dives”.
Battery Power Indicator And Low Battery Warning
The
IQ-400
has a unique visual Battery Power Indicator designed to give you
an advance notice of impending need to change the battery.
The Battery Power Indicator will always be seen during activation. The follow-
ing table 3.1 shows the various warning levels (see also Fig. 3.3).

The maximum depth and
dive time are zeros (as no
dives have yet been made),
the surface interval time is
0 hours 8 minutes (in this
case eight minutes after
activization), the tempera-
ture is 22°C [72°F] and the
present depth is 0.0m [0ft].
The personal/altitude
adjustment mode is A1. The
depth display will alternate
between present and maxi-
mum depth. The Low
Battery Warning (battery
symbol) indicates that the
battery is too low for diving.

WARNING
SET THE CORRECT PERSONAL/
ALTITUDE ADJUSTMENT MODE!
When diving at altitudes greater than 700 m [2300
ft] the personal/ altitude adjustment feature must be
correctly selected in order for the computer to cal-
culate 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 decompres-
sion sickness exist (see Section 3.5). Failure to prop-
erly select the personal/ altitude adjustment mode
correctly will result in erroneous data and can great-
ly increase the risk of decompression sickness.

FOR USE AT ALTITUDES
GREATER THAN 2400 m (8000 ft)!
Diving at altitudes above this limit may signifi-
cantly increase the risk of decompression sickness.
