2. GETTING ACQUAINTED
2.1. FUNCTIONS
You can select the dive computer model between the Regular Air Dive Computer,
Nitrox Dive Computer and Depth Gauge with Timer mode.
The COBRA multipurpose dive computer is an air integrated computer featuring
three dive computer modes (AIR, NITROX, GAUGE), three main operating
modes (TIME/STAND-BY, SURFACE, DIVING), three menu based main modes
(MEMORY, SIMULATION, SET) and 16 - 18 menu based submodes (review
separate Quick Reference Guide). You can scroll through the modes using the push
buttons. The mode indicator at the left side and the mode text at the bottom of the
display indicate the selected mode.
The timekeeping display is the default display of the instrument (Fig. 2.1.). If a
button is not pressed within 5 minutes, the dive computer beeps and returns to the
timekeeping display automatically (except in Diving and Simulation modes). The
timekeeping display shuts off after two hours, but pressing the PLAN or TIME
button activates it.
2.2. CONNECTING THE COBRA TO A REGULATOR
Upon purchasing the Cobra, Suunto strongly recommends you have your dealer
attach it to the fi rst stage of your regulator.
If you decide to attach it yourself, follow the steps outlined below:
1. Remove the high pressure (HP) port plug on the fi rst stage of your
regulator using an appropriate sized wrench.
2. Thread the high pressure hose of the Cobra into the port of your regula-
tor with your fi ngers. Tighten the hose fi tting with a 16 mm [5/8”]
wrench. DO NOT OVERTIGHTEN!
3. Attach the regulator to a charged scuba cylinder. Slowly open the valve.
Check for leaks by submerging the fi rst stage regulator in water. If leaks
are detected, consult your dealer.
