Through a combination of audible and visible alarms, the
IQ-
600
helps alert divers to a number of possibly hazardous
situations, including: violation of ascent rate or no-decompres-
sion status; and, whether mandatory decompression stops are
necessary or divers have ascended above a mandatory stop
ceiling. Nitrox-specific warnings occur when users exceed a
limiting PO
2
of 1.6 atmospheres, and when cumulative
exposure to elevated PO
2
s exceeds recommended limits.
If needed, the
IQ-600
can calculate decompression stop
requirements for stops as deep as 49 ft/15 m.
The
IQ-600
’s Random Access Memory (RAM) enables it to
hold and display log data on ten dives. Users can further
access up to a cumulative total of 30 minutes of dive-profile
information, sampled in one-minute intervals.
Depending on use, the
IQ-600
’s battery can last up to 18
months or more before needing replacement. Battery replace-
ment is recommended to be performed by an authorized
TUSA dealer, or by the consumer, following the instructions
appearing in this manual.
The IQ-600 fits TUSA’s CNC-3
™
Compact Navigational
Console. This console combines the IQ-600 with an analog
submersible pressure gauge (SPG) and easy-to-use top-and
side-reading compass. The console also features clip anchors
on either side, to help attach it to your BC. The IQ-600
computer module will also fit in most other standard instru-
ment consoles and circular wrist mounts.
