Contact Programming. As shipped from the factory,
the Depth Alarm is set for 130 feet.
Select Decompression Time Display (Total, Stop,
Both):
There are three options for the manner in
which the decompression time is displayed. If you
select TOTAL, the decompression time displayed will
indicate the total time you will spend in
decompression.
Watch the Ceiling depth change in order to identify
when to ascend to the next stop depth. If you select
STOP, the decompression time displayed will indicate
the time you must remain at the current Ceiling.
When this time is 0:00, the Ceiling depth will decrease
and the new stop time will be displayed. If you select
BOTH, the TOTAL time and STOP time will alternate
at the rate of once every 2 seconds. From the factory,
the unit is set to ‘Both’.
Repetitive Dive Dependent Nitrogen (Off or On):
This option allows the dive computer to consider
recent dive history’s effects on the nitrogen loading,
particularly if the diver engages in inverted profile
diving. If “On” the recent dive history is used to
compensate the nitrogen loading for the current dive.
The COMMANDER is shipped from the factory with
this feature set to ‘On’.
Temperature Dependent NDC Computations
(Normal or Reduced): This feature compensates the
decompression algorithm proportional to the ambient
water temperature. See User & Environmental
Adaptation, Water Temperature on page 34 for a
detailed description of this function. The
COMMANDER is shipped from the factory with this
feature set to ‘Normal’.
Select Altitude <2000 feet as One Zone (Off or On):
This option provides "actual" altitude for any given day
at any diving location as explained in the “ALTITUDE
ACCLIMATIZATION” on page 35. With changes in
barometric pressure due to temperature and weather
systems, it is possible, even expected, to have a
different apparent altitude at the same dive site from
day to day.
While the seamless means of monitoring provides the
most accurate decompression schedule, all altitudes
less than 2,000 feet above sea level can be treated in
the algorithm as sea level if so selected. With this
option ‘OFF’, the unit is calculating altitude in a
seamless fashion. With this option ‘ON’, altitudes less
than 2,000 feet above sea level will be treated as sea
level. Regardless of the selection, altitudes greater
than 2,000 feet above sea level will be treated in a
