BASICS
Welcome to your new i770R. The i770R 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 i770R
is easy to use, you will get the most out of your new i770R 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.
POWER
The i770R housing contains a rechargeable lithium battery similar to that of a cell phone. The level of battery
charge is displayed on the primary screens. Charge the battery fully before first use. With a full charge you can
expect to average 30 dive hours at 100% brightness before needing to recharge.
Keep in mind that the i770R screen is the biggest draw of power. Using full brightness settings will reduce the
interval between charges. This setting can be fully customized to your preferences in the i770R settings. Addition-
ally, the i770R screen will sleep after 10 minutes of inactivity to conserve power. Pressing any button will wake the
screen up again.
CHARGING THE BATTERY
Use only the included Aqua Lung cable to charge the battery. This process will take an average of 1.5 -2 hours
with a wall charger and 3 - 4 hours charging from a personal computer's USB port.
NOTE: It is recommended that you charge your i770R before any extended storage to avoid loss of
battery performance or shortened battery life.
