Page 2: Notices
The program within the i550C 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 i550C 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 i550C, a backup instrument system is highly recommended.
Page 4 • If you exceed certain limits, the i550C 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.

Welcome to your new i550C. The i550C is an easy to use dive computer utilizing a two button interface. Divers may choose between either Dive or Gauge Mode. Though the i550C is easy to use, you will get the most out of your new i550C if you take some time to familiarize yourself with its displays and operation.

GETTING STARTED BUTTONS The i550C utilizes 2 control buttons called the ADV (Advance) and SEL (Select) buttons. They allow you to select mode options and access specific information. They are also used to enter settings, activate the backlight, and acknowledge the audible alarm. Throughout this manual they will be referred to as the ADV and SEL buttons.

Page 13: Dtr (Dive Time Remaining)
DIVE FEATURES DTR (DIVE TIME REMAINING) The i550C constantly monitors No Decompression status and O2 Accumulation, and will display whichever time is the least amount available as DTR on the No Decompression Dive Main screen. The time being displayed will be identified by the NO DECO or O2 MIN icons.
Page 14: Asc Bar Graph
DS (DEEP STOP) When the DS selection is set to ON, it will trigger after descending deeper than 24 m (80 ft). The i550C then cal- culates (continually updating) a Stop Depth equal to ½ the Max Depth.

NOTE: New data will automatically overwrite the oldest data in memory when the memory becomes full. The i550C Log and Diverlog + Download data is stored separately in different partitions of the memory. The Log only stores a short summary of each dive. Alternately, the Diverlog + Download function stores much larger files for each dive.

DIVE OPERATION COMPLICATIONS The preceding information has described stress free casual dive operations. Your new i550C is also designed to help you to the surface in less than ideal situations. The following is a description of these. Take some time to familiarize yourself with these operations before diving your i550C.

Instrument Lens Protector. Small scratches will naturally disappear underwater. • Soak and rinse the i550C in fresh water at the end of each day of diving, and check to ensure that the areas around the Low Pressure (Depth) Sensor, water contacts, and buttons are free of debris or obstructions.
Page 50: Battery Replacement
• Check the metal contacts for any signs of stress or corrosion. WARNING: If damage or corrosion is found, return your i550C to an authorized Aqua Lung dealer, and DO NOT attempt to use it until it has received factory prescribed service.
Page 51: Altitude Sensing And Adjustment
• No adjustments are made during any time that the Wet Contacts are bridged. • When diving in high altitude waters from 916 to 4,270 m (3,001 to 14,000 ft), the i550C automatically adjusts to these conditions providing corrected depth, and reduced NO DECO (decompression) and O2 MIN (O satura- tion) times at intervals of 305 m (1,000 ft).
