NiTek He Owner’s Manual Page 19
The NiTek He enters Dive mode as soon as it enters the water. It does not count a
dive as having taken place, however, unless you remain below a depth of 5.0 feet/
1.5 meters for at least three minutes.
If you spend at least ten minutes above a depth of 5.0 feet/1.5 meters, the com-
puter will consider any further descent as a separate dive.
If your NiTek He is in default, an audible warning will sound as you enter the
water. (Horizontal bars will also appear in the FO
2
and FHe display, instead of a
percentage value.) If you hear this alarm, surface and set the NiTek He for your
actual gas mixture.
Prior to descending, always check one nal time to ensure the
gas mixture settings are correct.

Pressing and holding button B will cause the NiTek He to display current time of
day and temperature, as shown in Figure 11. Releasing button B returns the com-
puter to its normal Dive mode display.
While in Dive mode, you should be alert for the following warnings:

blinking.
