Suunto VYTEC DS - Manual

10 1.1.2. Dive Computer Limitations While the dive computer is based on current decompression research and technology, you must realize that the computer cannot monitor the actual physiological functions of an individual diver. All decompression schedules currently known to the authors, including th...

11 The timekeeping display is the default display of the instrument (Fig. 2.1.). If a button is not pressed within 5 minutes, the dive com puter beeps and returns to the timekeeping display automatically (except in Diving and Simula-tion modes). The timekeeping display shuts off after two hours, but...

13 2.4. WIRELESS CYLINDER PRESSURE TRANSMISSION The Vytec can be used together with an optional wireless cylinder pressure transmitter that can easily be attached to the high-pres-sure port of the regulator (Fig. 2.5). By using the transmitter the diver can bene fi t from cylin- der pressure and rem...

14 2.4.2. Pairing and Code Selection In order to receive wireless data the transmitter and the Vytec wrist unit need to be paired. During the pairing procedure the transmitter and wrist unit select a common transmission code. The transmitter turns on when the pressure exceeds 15bar [218 psi] and it ...

15 The selected transmission code can later be veri fi ed via the alternative display, by pressing the “TIME” button twice. If needed, the stored code can be manually erased in this display by pressing the “PLAN” (up) button and then pressing “MODE” (select). The Vytec will now erase the stored code...

17 QUIT 3. DIVING WITH THE VYTEC This section contains instructions on how to operate the dive computer and interpret its displays. You will fi nd that this dive computer is easy to use and read. Each display shows only the data relevant to that speci fi c diving situation. 3.1. BEFORE DIVING 3.1.1....

20 If the battery symbol is displayed in the Surface mode or if the display is faded or weak, the battery may be too low to operate the dive computer and battery replacement is recommended. NOTE! For safety reasons the backlight cannot be activated when the low battery warning is indicated by the ba...

21 The surface interval must be at least 5 minutes for a dive to be considered a repetitive dive. Otherwise, it is considered a continuation of the same dive. The dive number will not change and the dive time will continue, where it left off (see also section 3.6.2. “Dive Numbering”). 3.1.4. User De...

27 3.3.6. Safety Stops and Deep Stops If Deep Stops are not used a 3 minute Recom-mended Safety Stop is prompted after every dive to 10m depth ( fi g. 3.11). Continuous ascent rate violations will result in Mandatory Safety Stops ( fi g. 3.14). When enabled, Deep stops are calculated. The length of ...

28 plus • the time needed to reach the surface after the ceiling and safety stops have been completed. WARNING! YOUR ACTUAL ASCENT TIME MAY BE LONGER THAN DISPLAYED BY THE INSTRUMENT! The ascent time will increase if you: • remain at depth • ascend slower than 10 m/min [33 ft/min] or • make your dec...

29 lift you above the ceiling. Suunto recommends that decompression takes place deeper than 4 m [13 ft], even if the indicated ceiling is shallower. NOTE! It will take more time and more air to decompress below the ceil- ing than at the ceiling. WARNING! NEVER ASCEND ABOVE THE CEILING! You must not ...

30 DISPLAY ABOVE THE CEILING If you ascend above the ceiling during a de-compression stop, a downward pointing arrow will appear and a continuous beeping starts (Fig. 3.19.). In addition, an error warning Er reminds you that you have only three minutes to correct the situation. You must immediately ...

31 on Nitrox use result in longer no-decompression times and shallower maximum depths than div-ing with air. As a safety precaution the oxygen calculations in the computer are made with an oxygen per-centage of 1% + setO 2 % . When the dive computer is set in Nitrox mode the Dive Planning and Dive S...

33 After fi ve seconds the display will automatically revert to the original display. 3.4.3. Oxygen Limit Fraction (OLF) In addition to tracking the diver’s exposure to nitrogen, the instrument tracks the exposure to oxygen, if set to Nitrox mode. These calculations are treated as entirely separate ...

39 You are able to preset alarms before the actual dive. The user program-mable alarms can be set for maximum depth, dive time and time. The alarms activate when: • The preset maximum depth is reached • continuous beep series for 24 seconds or until any button is pressed. • the maximum depth blinks ...

40 3.8. HIGH ALTITUDE DIVES AND PERSONAL ADJUSTMENT The dive computer can be adjusted both for diving at altitude and also to increase the conservatism of the mathematical nitrogen model. 3.8.1. Altitude Adjustment When programming the instrument for the correct altitude, you need to select the corr...

42 mode (RGB50). See Table 3.6. To advise the diver that attenuated RGBM has been set, the Diver Attention Symbol is constantly displayed (Table 3.3.) TABLE 3.6. RGBM MODEL SETTINGS 3.9. ERROR CONDITIONS The dive computer has warning indicators that alert the user to react to certain situations that...

44 EXIT / QUIT! By pressing the SMART button for more than 1 second, any menu based function or submode can be quit and the dive computer will return directly to the Dive Mode.

Make sure that the spring bars get fully seated so they will not come off their holes. Console model: • Re fi t the dive computer in the console according the instructions of the co...

64 NOTE! It is imperative to wait at least 30 seconds before re-installing the transmitter battery. When the battery is re-installed the transmitter sends an overpressure (“---“) signal on code 12 for 10 seconds, after which it goes to normal operation, and shuts down after 5min. 9. Check that the n...
