Basics; Initial Activation - Aqua Lung i750TC Owner's Manual

BASICS

Welcome to your new i750TC. The i750TC is an easy to use dive computer utilizing a three button interface.
Divers may choose between three modes of functionality consisting of Dive, Gauge, and Free Mode. Though the
i750TC is easy to use, you will get the most out of your new i750TC if you take some time to familiarize yourself
with its displays and operation. Information has been organized into easy to follow sections to aid you in learning
all you need to know. There is also a glossary at the end of this guide for any terms that may sound unfamiliar.

INITIAL ACTIVATION

To activate the i750TC, press and release any button. The i750TC will also turn on if its metal contacts become
wet and you descend below 1.5 m (5 ft) for 5 seconds.
• Upon activation, the unit will display the Welcome screen and perform a diagnostic check. The i750TC checks
the display and voltage at this time to ensure that everything is within tolerance.
• It will also check ambient barometric pressure, and calibrate present depth as 0 m (ft). When at 916 m (3001 ft),
or higher, it will adjust for the higher altitude.
• After the Diagnostic check, the i750TC will display the Home Menu (or Dive Main if wet activation).
NOTE: The i750TC has no off button or command. If no buttons are pressed or dives made, the unit
will enter sleep mode after 2 minutes. Within 2 hours of no buttons being pressed or dives made, the
unit will shut itself off. However, the i750TC will stay on for a 24 hour period after a dive, counting
down FLY (time to fly) and DESAT (desaturation time) if a dive has been made.
