WARNING! THERE IS ALWAYS A RISK OF DECOMPRESSION ILLNESS (DCI) FOR ANY DIVE PROFILE EVEN IF YOU FOLLOW THE DIVE PLAN PRESCRIBED BY DIVE TABLES OR A DIVE COMPUTER. NO PRO- CEDURE, DIVE COMPUTER OR DIVE TABLE WILL PREVENT THE POSS IBILITY OF DCI OR OXYGEN TOXICITY! An individual’s physi- ological make up can vary from day to day. The dive computer cannot account for these variations. You are strongly advised to remain well within the exposure limits provided by the instrument to minimize the

WARNING! YOU ARE ADVISED TO AVOID FLYING ANY TIME THE COMPUTER COUNTS DOWN THE NO-FLYING TIME. ALWAYS ACTIVATE THE COMPUTER TO CHECK THE REMAINING NO-FLY TIME PRIOR TO FLYING! The computer goes into the stand-by display auto matically 5 minutes after the dive has ended. The stand-by display shuts off after two hours. Flying or traveling to a higher altitude within no-fl y time can greatly increase the risk of DCI. Review the recommendations given by Diver’s Alert Network (DAN) in chapter

WARNING! THE DIVE COMPUTER WILL NOT ACCEPT FRACTIONAL PER- CENTAGE VALUES OF OXYGEN CONCENTRATION. DO NOT ROUND UP FRACTIONAL PERCENTAGES! 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. If there is a desire to adjust the computer to provide more conservative calculations, use the personal adjustment feature to af- fect decompression calculations or reduce the PO setting to affect

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 Vytec provides many new and enhanced features that cannot be found in other dive computers, such as gas switching and optional wireless air-integration. Push button con- trols access a wide selection of choices. The display is optimized for the dive mode chosen. This air-integrated dive computer is a co

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 specifi c dive situation. To get the most from the safety benefi ts be sure to read the summary of the Reduced. 1.1. SAFETY PRECAUTIONS Do not attempt to use the dive computer without reading this instruction manual in it

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.S. Navy Tables, are based on theoretical mathematical models, which are in tended to serve as a guide to reduce the probability of decompression illness. 1.1.3.

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. Making the Vytec personal Fig. 2.1.

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 benefi t from cylin- der pressure and remaining air time data. In order to use the transmitter the wireless Fig. 2.4.

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 then starts sending pressure data together with a code number. During the pairing procedure the Vytec stores the above mentioned code number and starts displaying pressure values that are received w

The selected transmission code can later be verifi 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 and start displaying “SETC” allowing a new pairing with the trans- mitter. The alternative display showing the select-
ed code reverts to the main display after 15

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 Vytec (Fig.2.6 d). If the dive is started without that the Vytec and the transmitter have been properly paired, the Vytec will indicate that no cylinder data is available by displaying “OFF” (Fig. 2.6 e). TABLE 2.1.
