OVERVIEW
The i450T is equipped with an advanced digital compass. Compass Mode can be activated while in any other
operation mode by holding the SELECT button for at least 2 seconds.
• The i450T 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.
• The compass has both a Stand (Standard) and Ref (Reference) Mode.
• The compass is inaccurate when held ≥ 20°off of level. When this occurs the Tilt icon (see previous page) is
displayed and the current degree heading is temporarily removed from the display until the i450T is again level.
!
WARNING: You must become thoroughly familiar with setup and operation of the i450T Digital Com-
pass before using it as your primary device for navigation. Failure to do so could result in serious
errors relating to activities involving navigation.

STAND MODE (STANDARD MODE)
In this mode the compass behaves much like an analog compass. The dynamic arrow always points North. The
i450T will also give your current heading in both degrees and cardinal/intercardinal direction.
