Surface Mode (upon surfacing from a dive)

Once you surface from a dive, the NiTek X automatically

switches to surface mode after 10 minutes. However, if surface

interval is less than that time, the NiTek X will continue the dive.

In addition to the normal information displayed in surface mode

such as time of day, there is other information that is displayed

that pertains to the dive you just completed. This includes:

• Desaturation time

• Surface interval time

• Pressure Gas in Tissue (PGT) bar graph

• Oxygen limit index (OLI) bar graph

This information is displayed the screen until the NiTek X

calculates that it is no longer needed or after 24 hours have

passed since the last dive.

Note: If you are making repetitive dives, you need to pay

attention to your surface interval and use it in conjunction with

plan mode. This ensures that you stay within no-decompression

limits.

(1) Surface Interval Time: This is the amount of time you have

spent on the surface since your last dive if there is residual

nitrogen present from a previous dive. It is displayed up to 24

hours of surface interval time..

NOTE: The Surface Interval Time will reset if the battery

is removed.

(2) Desaturation time: This is the amount of time, expressed in

hours and minutes, that must pass before the residual nitrogen

levels drop to a point where subsequent dives are treated as a
