GEO 4.0 OPERATING MANUAL

BASICS

Welcome to your new Geo 4.0. The Geo 4.0 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 Geo 4.0 is easy to use, you will get the most out of your new

Geo 4.0 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.

ACTIVATION

Geo 4.0 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 waking the Geo 4.0 up, the correct

Date and USA Pacic Time will be displayed and it will be ready to operate with full functions.

To wake the Geo 4.0 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 Geo 4.0 is brought out of the Deep Sleep mode, it can only be placed back into it by the factory.

STANDBY (POWER SAVING) MODE

The Geo 4 shall enter Standby mode 10 minutes after Norm, Gauge, or Free Surface Modes have been activated (or 10 minutes after the post dive

transition period has ended) and no button presses or dives have been initiated.

NOTE: Bluetooth function shuts down during Standby Mode to save battery life.
