● This watch has a built-in pressure sensor to measure the
altitude (above sea level) and indicates the altitude rank
graphically in four levels.
● Residual nitrogen, no-decompression limits for the next dive
and other data are calculated taking into account the current
altitude.
● As you move across altitude ranks, the watch re-calculates
residual nitrogen on the spot.

Notes:
1. The altitude range in the above table provides general guideline
of altitude only, and the altitude rank indication does not indicate
a specific altitude.
2. If the watch senses an altitude change across altitude ranks, the
residual nitrogen indicator may appear even while you are on the
surface. This is not a malfunction.
● The measurement units of depth and temperature can be
selected from “meters (m) and centigrade (° C)” and “feet (ft)
and Fahrenheit (° F)”.
HOW TO SET THE DEPTH & TEMPERATURE UNITS
Press to show DIVE PLAN display.
A
Press for 4 to 5 seconds to change over the depth
and temperature units.
* With each press of the button, the units of depth and
temperature change over alternately between “meters and
centigrade” and “feet and Fahrenheit”.

Note:
Once the units of depth and temperature are set in the DIVE PLAN
display, those in the DIVE LOG display and the DIVE mode will also
be set accordingly.
