BASICS
Welcome to your new i450T. The i450T is an easy to use dive computer utilizing a four button interface. Divers
may choose between four modes of functionality consisting of Watch, Dive, Gauge, and Free Mode. Though the
i450T is easy to use, you will get the most out of your new i450T 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
i450T Watch/Dive Computers are placed in a Deep Sleep mode prior to being shipped from the factory. The intent
is to extend storage life of the Battery for up to 7 years, before the unit is initially placed into service.
In this mode, Date and Time are updated as they normally would be. However, they are not displayed. Upon wak-
ing the i450T up, the correct Date and USA Pacific Time will be displayed and it will be ready to operate with full
functions.
To wake the i450T up from Deep Sleep mode, simultaneously depress the upper/right (SELECT) and lower/left
(ADV) buttons for 3 seconds until the display comes ON displaying the Watch Main Time screen, then release
them.
NOTE: Once the i450T is brought out of the Deep Sleep mode, it can only be placed back into it by the
factory.
