  • Page 4: Introduction

    1. Introduction Congratulations on your choice of the TUSA IQ-800 Dive Computer. The IQ-800 is a compact and sophisticated dive instrument that will give you reliable, trouble free performance, dive after dive. The information in this manual has been developed for your safety.
  • Page 5 It is not intended for use by persons who lack the qualifications, and thus may not be able to identify, assess, and manage the risks scuba diving entails. Use of the IQ-800 in conjunction with Enriched Air Nitrox (EANx) further requires that the diver be trained and certified for Nitrox diving.
  • Page 6 WARNINGS The IQ-800 is designed to be used by only one diver at a time. Divers should not share a single IQ-800, or any dive computer, on the same dive. Additionally, no diver should lend his or her IQ-800 to anyone else until it calculates that no measurable residual nitrogen remains after previous dives, and displays neither the “Desaturation Time”...

  • Page 7: Accessing Display Modes

    Time Mode. To access other modes, you may need to push one of the three large buttons on the sides of the IQ-800. These are the A, B, and C buttons. (Fig. 1) You will find these buttons easy to use. In some instances, you may need to press a button once and release it to achieve the desired result.

Ascent Rate warning: If the ascent rate is exceeded, the SLOW icon, current depth, ascent rate bar graph, and SLOW mode icon will blink.
  • Page 31 • Decompression stop violation warning: When current depth is shallower than the indicated decompression stop depth, the IQ-800 will alert the diver with the display and the alarm. If the diver returns to the indicated water depth, the warning display stops blinking. This information is recorded in the dive log.
  • Page 32 • Oxygen Limit Indicator warning: When the OLI graph reaches 7 or 8 bars, the IQ-800 responds with a flashing display and the alarm. There are two types of warnings, as described below. (Fig. 31) 7 bars displayed: The OLI bar graph will blink for 15 seconds.
  • Page 33 The warning is recorded in the log. (Fig. 33) Figure 33 WARNING An IQ-800 displaying an “Out of Range” warning is incapable of displaying other critical information such as depth, time, ascent rate, , OLI, and deco stop violations, and required decompression stops.
  • Page 34 Safety Stop warning: There are two types of safety stop warnings. The diver is alerted to the start of the safety stop by a blinking stop icon and SAFE indicator. If the safety stop has started and the depth becomes less than 5 feet (1.4m), the remaining stop time will also blink.
