3 W ARNING! THERE IS AL WA YS A RISK OF DECOMPRESSION ILLNESS (DCI) FOR ANY DIVE PROFILE EVEN IF YOU FOLLOW THE DIVE PLAN PRESCRIBED BY DIVE T ABLES OR A DIVE COMPUTER. NO PRO- CEDURE, DIVE COMPUTER OR DIVE T ABLE WILL PREVENT THE POSS IBILITY OF DCI OR OXYGEN TOXICITY! An individual’ s physi- ological make up can vary from day to day .
4 W ARNING! YOU ARE ADVISED TO A VOID FL YING ANY TIME THE COMPUTER COUNTS DOWN THE NO-FL YING TIME. AL WA YS ACTIV A TE THE COMPUTER T O CHECK THE REMAINING NO-FL Y TIME PRIOR TO FL YING! The computer goes into the stand-by display auto matically 5 minutes after the dive has ended.
5 W ARNING! THE DIVE COMPUTER WILL NOT ACCEPT FRACTIONAL PER- CENT AGE V ALUES OF OXYGEN CONCENTRA TION. DO NOT ROUND UP FRACTIONAL PERCENT AGES! For example, 31.8% oxygen should be entered as 31%. Rounding up will cause nitrogen percentages to be understated and will affect decompression calcu- lations.

8 1. INTRODUCTION Congratulations on your purchase of the SUUNTO VYTEC advanced dive computer . The Vytec builds on the Suunto tradition of delivering feature-rich dive computers. The Suunto V ytec provides many new and enhanced features that cannot be found in other dive computers, such as gas switching and optional wireless air-integration.
9 In order to optimize how to respond to different added risk situations an additional category of stop, referred to as a Mandatory Safety Stop, has been introduced. Also a countdown for the Recommended Safety Stop is included. The combination of stop types will depend on the speci fi c dive situation.
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 the U.
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 pressing the PLAN or TIME button activates it.
12 Press the SMART (MODE) button • T o activate the dive computer . • T o change from the Surface Mode to the menu based modes. • T o select, con fi rm or quit a submode (short press). • T o immediately exit any submode to the Surface Mode (long press).
13 2.4. WIRELESS CYLINDER PRESSURE TRANSMISSION The V ytec 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 remaining air time data.
14 2.4.2. Pairing and Code Selection In order to receive wireless data the transmitter and the V ytec wrist unit need to be paired. During the pairing procedure the transmitter and wrist unit select a common transmission code.
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).
16 In case the transmitter battery is running low , a low battery warning “LOBT” will be transmitted and displayed intermittently with the pressure reading on the V ytec (Fig.
17 QUIT 3. DIVING WITH THE VYTEC This section contains instructions on how to operate the dive computer and interpret its displays. Y ou 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.
18 • the instrument displays correct units of measurement (Metric/Imperial) • the instrument displays correct temperature and depth (0.0 m [0 ft]) • the buzzer beeps IIf the optional wireless pressure trans-mitter is used (see chapter 2.
19 The Battery Power Indicator can always be seen when the Dive Mode is activated. The electroluminescent backlight will be on during the battery check. The following T able and Figure show the various warning levels. T ABLE 3.1. BA TTERY POWER INDICA TOR Display Operation Figure 3.
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 battery symbol.
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.
22 3.2.2. Mandatory Safety Stop When the ascent rate exceeds 12 meters/min [40 ft] momentarily or 10 meters/min [33ft] con- tinuously the micro-bubble build-up is predicted to be more than allowed for in the decompres- sion model. The Suunto RGBM calculation model responds to this by adding a Mandatory Safety Stop to the dive.
23 3.2.3. Deep Stops The Suunto V ytec allows the user to choose a deep stop algorithm instead or the traditional recommended safety stop. Deep Stops are decompression stops that occur deeper than traditional stops, with the purpose of minimizing microbubble formation and excitation.

25 shown in the left center window of the display . The calculation is always based on the actual pressure drop in your cylinder and will automatically adapt to your cylinder size and current air consumption. The change in your air consumption will be based on constant one second interval pressure measurements over 30 - 60 second pe riods.
26 Red Zone – As all of the bars appear (red zone), your no-decompression stop time has become zero and your dive has become a decompression stop dive (for more information see section 3.3.6. “Decompression dives”). 3.3.5. Ascent Rate Indicator The ascent rate is shown graphically along the right side of the display as follows: T ABLE 3.
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. 3.1 1). Continuous ascent rate violations will result in Mandatory Safety Stops ( fi g. 3.14). When enabled, Deep stops are calculated.

30 DISPLA Y 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.
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 % .
32 label NITROX, is shown after activation. In Dive Planning mode the Nitrox display shows (Fig. 3.21.): • the oxygen percentage, labeled with O 2 %, is shown in the left side of the center window .
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.
34 set maximum oxygen partial pressure. T issue calculation during dive is based on the mix you have selected. The V ytec allows gas change to enabled gas mixes during the dive.
35 T ank pressure and ascent rate indicator are also displayed during the dive (Fig. 3.28.). Remaining Air Time, temperature and current time are shown in the alternative display when the TIME button is pressed. NOTE! If you dive with the Gauge mode, it is not possible to change between the modes within 48 hours.
36 Or when the TIME button is pressed once or twice: • the current time, shown as TIME instead of the DIVE TIME • the current temperature with °C for Centigrade [or °F for Fahrenheit] • the surface time in hours and minutes (separated by a colon), telling the duration of the present surface interval (Fig.
37 in the Planning Mode will increment to the next higher number if another dive is made. T ABLE 3.3. WARNING SYMBOLS 3.6.3. Flying After Diving The no- fl ying time is shown in the center window next to the airplane image. Flying or travelling to a higher altitude should be avoided at any time the computer counts down the no- fl ying time.
38 • If a diver had less than 2 hours total accumulated dive time in the last 48 hours, then a 12 hour surface interval before fl ying is recommended. • Following any dive that required a decompression stop, fl ying should be delayed for at least 24 hours, and if possible, for 48 hours.
39 Y ou 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.
40 3.8. HIGH AL TITUDE 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 correct Altitude Mode according to T able 3.

57 5. CARE AND MAINTENANCE This SUUNTO dive computer is a sophisticated precision instrument. Though designed to withstand the rigors of scuba diving you must treat it with proper care and caution as any other precision instrument.
58 • Protect the unit from shock, extreme heat, direct sunlight, and chemical attack. The dive computer cannot withstand the impact of heavy objects like scuba cylinders, nor chemicals like gasoline, cleaning solvents, aerosol sprays, adhesive agents, paint, acetone, alcohol etc.
59 computer , there is a leak. A leak must be corrected without delay , as mois- ture will seriously damage the unit, even beyond repair . SUUNTO does not take any responsibility for damage caused by moisture in the dive computer , if the instructions of this manual are not carefully followed.
60 TOOLS REQUIRED • A fl at 1.5 mm screwdriver or a special tool for spring bars (K5857). • Soft cloth for cleaning. • Needlenose pliers or large screwdriver for turning securing ring. BA TTERY REPLACEMENT The battery and the buzzer are located in the back of the instrument in a separate compartment, the parts of which are shown in Fig.
61 8. Check the condition of the O-ring; a defective O-ring may indicate sealing or other problems. Dispose the old O-ring, even if it seems to be in good condition. 9. Check that the battery compartment, battery holder and lid are clean. Clean with soft cloth if necessary .
62 • Assemble the shorter part of the strap. Use the spring bar tool or small screwdriver to compress the spring bars. 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 console.
63 CAUTION! Defects caused by improper battery installation are not covered by the warranty . BA TTERY KIT The transmitter battery kit includes a 3.0 V CR ˚ AA lithium cell battery and a lubricated O-ring. When handling the battery do not make contact with both of the poles at the same time.
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.
65 T ABLE 6.1. NO-DECOMPRESSION TIME LIMITS (MIN) FOR V ARI- OUS DEPTHS (M) FOR THE FIRST DIVE OF A SERIES T ABLE 6.2. NO-DECOMPRESSION TIME LIMITS (MIN) FOR V ARI- OUS DEPTHS [FT] FOR THE FIRST DIVE OF A SERIES AL TITUDE DIVING The atmospheric pressure is lower at high altitudes than at sea level.
66 Before high altitude diving, the instrument must be set to the Altitude Adjustment mode to adjust the calculations for the new altitude. The maximum partial pressures of nitrogen allowed by the mathematical model of the dive computer are reduced according to the lower ambient pressure.
67 Also on repetitive dives adjustment may be applied to the maximum al- lowable nitrogen overpressure in each theoretical tissue group. Depending on circumstances Suunto RGBM will adapt the decompres.
68 • the blinking of the bar graph stops, when the PO 2 is below 0.5 bar • audible alarms are given and the actual PO 2 value blinks when it exceeds the preset limit • in dive planning the maximum depth according to the O 2 % and maximum PO 2 selected.
69 Other displays: • Dive time: 0 to 999 min, counting starts and stops at 1.2 m [4 ft] depth. • Surface time: 0 to 99 h 59 min. • Dive counter: 0 to 99 for repetitive dives. • No-decompression time: 0 to 199 min (- - after 199). • Ascent time: 0 to 99 min (- - after 99).
70 and dive violations. The “M” values are tracked up to 100 hours after a dive. • The EAN and oxygen exposure calculations are based on recommendations by R.
71 The following conditions have an affect on the expected battery lifetime: • The length of the dives. • The condition in which the unit is operated and stored (e.g. temperature/cold conditions). Below 10°C [50°F] the expected battery lifetime is about 50-75% of that at 20°C [68°F].
