Understanding Default Mode
Once the computer’s gas mixes are programmed, the settings are
stored in the computer unless the battery is replaced. When the
battery is replaced, all gas mixture settings change to 21 percent
oxygen, 00 percent helium, and 79 percent nitrogen.
Note: The computer will retain all decompression and dive-log
information when the battery is replaced.
Note: Removing the battery when the dive computer is in
decompression violation mode will not clear any decompression
violation information – the countdown will resume from the time
the battery had been removed.
Note: You should not rely on the NiTek X as the sole means of
tracking your exposure to elevated partial pressures of oxygen. It
is recommended that you use either a second computer or
another tracking method, such as dive tables.
