slowly drift from the ideal. It is recommended that this
clock be periodically set to local time via the Analyst

.
Metric or Imperial: The diver may select whether the
data is computed and displayed in Metric or Imperial
units. The COMMANDER may be ordered either way
as shipped from the factory.
Selectable Ascent Rate Bar Graph (Fixed or
Proportional):
This option determines whether the
Ascent Rate bar graph indicates the speed of ascent
or the percentage of the selected maximum ascent
rate. The COMMANDER is shipped from the factory
as ‘Proportional’ (percentage).
Selectable Variable-By-Depth Ascent Rate Alarm
(On or Off):
This option gives the diver the ability to
utilize a fixed ascent rate warning or a warning based
on depth. Should the diver prefer the fixed ascent
rate warning the diver can select the maximum ascent
rate limit from 20 to 60 feet per minute (See next
topic). As shipped from the factory, this is set to ON.
If the VARIABLE rate is selected then the warning will
illuminate based on the following table:
DEPTH AVERAGE ASCENT RATE
60 feet and deeper 60 feet per minute
60 to 30 feet same as depth
Shallower than 30 feet 30 feet per minute
Selectable Fixed Ascent Rate Alarm Limit: If
Variable-By-Depth Ascent Rate Alarm was set to OFF
from the above topic, the user may enter the desired
Ascent Rate for the alarm to sound.
Ascent Rate for Deco Predictions (20 to 60): This
option allows the diver to select the ascent rate to be
used in the forecasting of the displayed Total
Decompression time. The COMMANDER is shipped
from the factory with this option set to 60.
Ascent Rate Responsiveness (0 to 7): This option
determines the responsiveness or sensitivity of the
Ascent Rate Bar Graph. Zero is highly responsive
and seven is very slow. This feature is set to three as
shipped from the factory.
Remaining Time Responsiveness (0 to 7): This
determines the responsiveness of the Remaining
Time information that is displayed. Zero is highly
responsive and seven is very slow. This feature is set
to three as shipped from the factory
Max Depth Alarm: This option allows the diver to
select a maximum depth below which the diver does
not wish to descend before an alarm is sounded. This
function is disabled when in the Decompression
Mode. This option may also be set via the Touch
