  • Page 5: Introduction

    Introduction Congratulations on your selection of the Zeagle N2iTion Dive Computer. The N2iTion is a compact and sophisticated dive instrument that will give you a reliable, trouble free performance, dive after dive. Please read and understand this manual completely before using your new Zeagle N2iTion Dive Computer.
  • Page 6 Use of the N2iTion in conjunction with Enriched Air Nitrox (EANx) further requires that the diver be trained and certified for Nitrox diving.
  • Page 7 WARNINGS The N2iTion is designed to be used by only one diver at a time. Divers should not share a single N2iTion, or any dive computer, on the same dive. Additionally, no diver should lend his or her N2iTion to anyone else until it calculates that no measurable residual nitrogen remains after previous dives, and displays neither the “Desaturation Time”...

  • Page 8: Accessing Display Modes

    Surface Mode. To access other modes you may need to push one of the three large, grey buttons on the N2iTion’s face. These are the A (LEFT), B (MODE), and C (RIGHT) buttons. (Fig. 1) You will find these buttons easy to use. In some instances you may need only press a button once and release it to achieve the desired result.

  • Page 9: Time Mode

    5. Time Mode Time mode is the N2iTion’s default mode. In this mode the screen displays a minimum of the current date and time of day. Within 24 hours of surfacing from a dive, the N2iTion will display additional information while in Time Mode.
