Using the NiTek Trio
46 NiTek Trio Dive Computer User Manual v1.2
Altitude operation
The NiTek Trio adjusts automatically for diving at altitudes of up to
19,685 feet (6,000 meters). To show that the NiTek Trio has made the
altitude adjustment, it displays the altitude settings using symbols
representing mountains.
Altitude rank symbols
Symbol Altitude range
No symbol Sea Level to 3,281 feet (1000 meters)
2,297 to 5,906 feet (700 to 1,800 meters)
4,593 to 8,530 feet (1,400 to 2,600 meters)
7,546 to 19,685 feet (2,300 to 6,000 meters)
E Out of range above 19,685 feet (6,000 meters)
Prior to using the NiTek Trio at altitudes substantially above sea level,
you should find out what the actual altitude of your dive site is. Make
certain that the altitude settings the NiTek Trio displays accurately
match the altitude you are at.
Notes
• Do not use the NiTek Trio unless the altitude settings accurately
match the actual height above sea level you are diving in. Doing so
could cause the NiTek Trio to display inaccurate information.
• Do not use the NiTek Trio when the “E” symbol is displayed. This
means that you are above an altitude of 19,685 feet (6,000 meters),
which is beyond the NiTek Trio’s ability to function accurately.
• Do not place the NiTek Trio in dive mode when making sudden,
substantial changes in altitude, such as when flying in an airplane.
This can be caused by storing the NiTek Trio with wet dive gear,
which can touch its external electrical contacts and cause it to enter
