The Aqua Lung i770R may display an error related to altitude and restrict access to the operating interface if the altitude level exceeds the device's tested or supported limits. The i770R has altitude settings that adjust for changes in atmospheric pressure, and operating beyond these limits may prevent proper function. Additionally, if the altitude settings are not correctly configured, the dive computer may enter a restricted mode to prevent inaccurate calculations that could compromise diver safety.

Summary of Contents for Aqua Lung i770R

Page 2: Notices
The program within the i770R simulates the absorption of inert gases into the body by using a mathematical model. This model is merely a way to apply a limited set of data to a large range of experiences. The i770R dive computer model is based upon the latest research and experiments in decompression theory.
Page 3: Warnings
This is an important reason for not pushing the tables, oxygen exposure limits, or entering decompression without proper training. If you dive in situations where your trip would be ruined or your safety would be jeopardized by losing the use of your i770R, a backup instrument system is highly recommended.
Page 4 • If you exceed certain limits, the i770R will not be able to help you get safely back to the surface. These situations exceed tested limits and can result in loss of some functions for 24 hours after the dive in which a violation occurred.

GETTING STARTED ACTIVATION To activate the i770R, press and release any button. The i770R 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 Activation screen and perform a diagnostic check. The i770R checks the display and voltage at this time to ensure that everything is within tolerance.

Small scratches will naturally disappear underwater. • Soak and rinse the i770R in fresh water at the end of each day of diving, and check to ensure that the areas around the low pressure (depth) sensor, charging port, water contact, and buttons are free of debris or obstruc- tions.

• No adjustments are made during any time that the water contacts are bridged. When diving in high altitude waters from 916 to 4,270 meters (3,001 to 14,000 feet), the i770R automatically ad- justs to these conditions providing corrected depth, and reduced No Decompression and O2 Times at intervals of 305 meters (1,000 feet).
