Overview - Aqua Lung i750TC Owner's Manual

OVERVIEW

The i750TC is equipped with an advanced 3D digital compass. Compass Mode can be activated while in Dive,
Gauge, or Free operation modes by holding the SELECT button for at least 2 seconds.
• The i750TC reverts back to the previous operation mode after 1 minute unless the Compass Mode is reset by
pressing any of the buttons. See the Timeout section at the end of this chapter for further details.
• When the i750TC is held almost vertical or completely upside down, the heading and cardinal points are tempo-
rarily removed from the display until the i750TC is again level.
• When no heading is set, the heading degrees and diver's direction (lubber line) remain green.
• Once a heading is set, the heading degrees and diver's direction (lubber line) are green when on heading, red
when on reciprical heading, and amber when off heading.
NOTE: Similar to an analog compass, magnetic and ferrous metals can cause erratic and erroneous
readings.
