    1. WELCOME TO THE WORLD OF SUUNTO DIVING INSTRUMENTS Suunto Vyper was designed to help you get the most out of your diving. After reading this manual and becoming familiar with the functions of your dive computer, you'll be ready to take the plunge into a whole new world of diving.

When WARNING diving at altitudes greater than 300 m/1,000 ft the Altitude Adjustment feature must be correctly selected in order for the computer to calculate the decompression status.The dive computer is not intended for use at altitudes greater than 3,000 m/10,000 ft. Failure to select the correct Altitude Adjustment setting, or diving above the maximum altitude limit will result in erroneous dive and planning data.

    3. SUUNTO AT A GLANCE 3.1. Navigating in the menus Suunto Vyper has four main operating modes - TIME mode (TIME), DIVE mode (DIVE), PLAN mode (PLAN), and MEMORY mode (MEMORY) – as well as the COMPASS submode, which can be activated from either TIME or DIVE modes. To toggle between the main modes, press the MODE button.

    BEFORE getting into the water. 4.1. TIME mode settings The first thing you'll want to do with your Suunto Vyper , is to modify the TIME mode settings: the time, alarm, date, units, backlight, and tones. In this section, we look at how to do this.

    NOTE displays by pressing the UP/DOWN buttons. 4.3.1. Compass display The Suunto Vyper displays the compass as a graphical representation of a compass rose. The rose displays the cardinal and half cardinal points, in addition to which, the current bearing is also displayed numerically.

  • Page 14: Compass Settings

    You can define the compass settings ( calibration, declination and time-out) when in COMPASS mode: Calibration Because of changes in the surrounding magnetic field, the Suunto Vyper electronic compass occasionally needs to be re-calibrated. During the calibration process, the compass adjusts itself to the surrounding magnetic field and to tilting. As a basic rule, you should calibrate the compass whenever it doesn t seem to operate properly, or after replacing the dive computer's battery.
  • Page 15 Move to another location and try to calibrate the compass again. If the calibration continues to fail, contact an authorized Suunto service center. Declination You can compensate for the difference between true north and magnetic north by adjusting the compass declination.

    It is a significant advance on the classic Haldane models, which do not predict free gas. The advantage of Suunto RGBM is additional safety through its ability to adapt to a variety of situations and dive profiles.

  • Page 17: Nitrox

    5.4. Nitrox Diving with nitrox provides you with an opportunity to increase bottom times or reduce the risk of decompression illness by reducing the nitrogen content in the gas mix. However, when the gas mix is altered, the oxygen content of the mix is generally increased. This increase exposes the diver to an oxygen toxicity risk not usually considered in recreational diving.

    In order to use the transmitter, the wireless integration needs to be enabled in your Suunto Vyper 's settings. To enable or disable the wireless integration refer to Section 5.8.10. Setting the tank pressure. 5.7.1. Installing the wireless transmitter When purchasing the Suunto Vyper , we strongly recommend that you have your Suunto representative attach the transmitter to the first stage of your regulator.

    RGBM model. The default setting is 100%, which gives full RGBM effect. Suunto strongly advises you to use full RGBM effect. Statistically, very experienced divers have less incidents with DCI. The reason for this is unknown, but it is possible that some level of physiological and/or psychological accommodation can take place when you are very experienced as a diver.

  • Page 27: Safety Stops

    The Suunto RGBM calculation model responds to this by adding a Mandatory Safety Stop to the dive. The time of this Mandatory Safety Stop depends on the severity of the ascent rate excess.

  • Page 28: Deep Stops

    Deep Stops are safety stops that occur deeper than traditional stops, with the purpose of minimizing microbubble formation and excitation. The Suunto RGBM model calculates deep stops iteratively, placing the first stop about halfway between the maximum depth and the ceiling depth. After the first Deep Stop is completed, another Deep Stop will be prompted halfway to the ceiling, and so on until the ceiling depth is reached.

    Filling your BC affects the air time calculation due to the temporary NOTE increase in air consumption. A change of temperature will affect the cylinder pressure and NOTE consequently the air time calculation. Low Air Pressure Warnings The dive computer will warn you with three audible double beeps and a blinking pressure display when the cylinder pressure reaches 50 bar/725 psi.
  • Page 32 In such cases, it is more manageable to maintain an additional distance below the ceiling, to make sure that the waves do not lift you above the ceiling. Suunto recommends that decompression takes place deeper than 4 m/13 ft, even if the indicated ceiling is shallower.
  • Page 33 Display below the floor The blinking ASC TIME and an upward pointing arrow indicate that you are below the floor. You should start your ascent immediately. The ceiling depth is shown on the left side, and the minimum total ascent time on the right side, of the center window. Below is an example of a decompression dive without Deep Stops, below the floor.

    If no button is pressed in 15 seconds, the dive computer will go back NOTE to the dive display without changing the gas mix. Upon ascent, the computer prompts you to change gas when the PO level you have set for the next mix allows a gas change. The prompt is an audible 3 beeps and the current O mix starts to blink.
