2.2.1. Time Mode
<Normal>
< After a dive >
Description of Functions: This mode is usually shown
•
Current time: This is the current time.
•
Current date: This is the current date.
•
Battery indicator Icon: This displays the current battery voltage.
•
PGT (Pressure Gas in Tissue) graph: This indicates the level of Nitrogen with nine level
indicators.
•
OLI (Oxygen Limited Indicator) graph: This indicates the level of Oxygen limit with eight
level indicators.
•
Nitrox Icon: This Icon is ON when NITROX has been set for MIX1 or MIX2.It blinks if the
MIX1 and MIX2 setting is the default setting.
•
Desaturation time (DESAT): This indicates the time remaining of nitrogen until the body’s
internal nitrogen is desaturated. The time is counted down to 0:00, it turns off after 1
minute.
•
Surface time (SURF.T): This is interval time after dive. Surface time is counted starting
from when the depth shown in Dive mode reaches 1.5 meters (5 feet) or less. If the depth
changes back to 1.5 meters (5 feet) or more in less than 10 minutes, the previous dive mode
is continued. Surface time is continued for 48 hours. After that, surface time is turned off
after 1 minute.
•
Mode: This is the display, which shows Time mode.
•
Don’t Fly Icon: While computer calculates desaturation time, this icon turned on at Time
Mode. When the computer has finished calculating desaturation time and Time Mode is over
12 hours, this Icon is turned off.
•
Gage mode Icon: In gage mode,the Icon is on.

<Battery indicator icon>
This displays the current battery power reserve status (in voltage).
When battery voltage is 2.8V or above, battery Icon is not shown.
When battery voltage is 2.6 to 2.7 V, battery Icon comes on and blinks.
When battery voltage is less than 2.6 V, battery Icon is on constantly.
You cannot go to dive mode while the battery indicator Icon is blinking or ON. This Icon can be
displayed during all modes except dive mode.
Measurement of battery voltage is automatically performed during all modes except PC
transfer mode and dive mode.
<Altitude rank>
Altitude rank
：
The computer automatically measures and calculates the current location's
altitude and displays the corresponding altitude rank. The relation between altitude rank
levels and altitudes are shown below. A new altitude measurement and calculation is made
once every ten minutes.
When the altitude is over 6000 meters (19680 feet), the Icons of altitude rank and ‘Err’ blink
and the dive computer cannot be used until the altitude drops to a lower level(under 6000
meters (19680 feet)). The calculations of PGT, OLI and desaturation time are stopped when
altitude is over 6000 meters (19680 feet), and ‘Err’ is displayed. But surfase time is continued
to be counted.
When the altitude is less than 6000 meters (19680 feet), the display shown before reaching
that altitude is displayed again once the altitude drops to a lower level. The same displays and
processing occur if the altitude cannot be measured for any reason.
Altitude measurements are made during all modes except dive mode and PC transfer mode.
Display of the current altitude rank Icon occurs in Time Mode and Plan Mode (In dive log
mode, a rank at a dive is displayed.)
