1. WELCOME TO THE WORLD OF SUUNTO DIVE COMPUTERS

Suunto Vyper Air wristop dive computer is 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.

With integrated digital compass and gas switching, Suunto Vyper Air simplifies your diving experience because all the information you need relating to depth, time, tank pressure,decompressionstatus,anddirectionisavailableononeeasy-to-readscreen. TheSuuntoVyperAirUser'sGuidecontainsvitallyimportantinformationwhichenables you to become familiar with your Suunto wristop dive computer. To understand the use, displays, and limitations of the instrument before using it, please read this user's guide carefully, and save it for further reference. Note also that a glossary is included at the back of the user's guide to help you understand dive-specific terminology.

2. WARNINGS, CAUTIONS, AND NOTES

Throughout this user's guide, important safety icons are displayed. Three classifications are used to separate these icons by their order of importance:

WARNING	is used in connection with a procedure or situation that may result
	in serious injury or death
CAUTION	is used in connection with a procedure or situation that will result
	in damage to the device
NOTE	is used to emphasize important information

Before you go on to read the user's guide itself, it is extremely important that you read the following warnings. These warnings are intended to maximize your safety while using Suunto Vyper Air and must not be ignored.

WARNING	YOU MUST READ the leaflet and user guide for your dive com-
	puter. Failure to do so may lead to improper use, serious injury
	or death.
WARNING	ALLERGIC REACTIONS OR SKIN IRRITATIONS MAY OCCUR
	WHEN PRODUCT IS IN CONTACT WITH SKIN, EVEN THOUGH
	OUR PRODUCTS COMPLY WITH INDUSTRY STANDARDS.
	IN SUCH EVENT, STOP USE IMMEDIATELY AND CONSULT
	A DOCTOR.

WARNING	NOT FOR PROFESSIONAL USE! Suunto dive computers are
	intended for recreational use only. The demands of commercial
	or professional diving may expose the diver to depths and condi-
	tions that tend to increase the risk of decompression illness (DCI).
	Therefore, Suunto strongly recommends that the device not be
	used for any commercial or professional diving activities.
WARNING	ONLY DIVERS TRAINED IN PROPER USE OF SCUBA DIVING
	EQUIPMENT SHOULD USE A DIVE COMPUTER! No dive
	computer can replace the need for proper dive training. Insufficient
	or improper training may cause a diver to commit errors that may
	lead to serious injury or death.
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 PROCEDURE, DIVE COMPUTER OR DIVE
	TABLE WILL PREVENTTHE POSSIBILITYOF DCI OR OXYGEN
	TOXICITY! An individual’s physiological 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 risk of DCI. As an
	added measure of safety, you should consult a physician regarding
	your fitness before diving.

WARNING	SUUNTO STRONGLY RECOMMENDS THAT SPORT DIVERS
	LIMIT THEIR MAXIMUM DEPTH TO 40 M/130 FT OR TO THE
	DEPTH CALCULATED BY THE COMPUTER BASED ON THE
	SELECTED O2% AND A MAXIMUM PO2 OF 1.4 BAR! Exposure
	to greater depths increases the risk of oxygen toxicity and decom-
	pression illness.
WARNING	DIVES WITH REQUIRED DECOMPRESSION STOPS ARE NOT
	RECOMMENDED. YOU SHOULD ASCEND AND BEGIN DE-
	COMPRESSION IMMEDIATELY WHEN THE DIVE COMPUTER
	SHOWSYOU THAT A DECOMPRESSIONSTOP IS REQUIRED!
	Note the blinking ASC TIME symbol and the upward pointing ar-
	row.
WARNING	USE BACK-UP INSTRUMENTS! Ensure that you use back-up
	instrumentation, including a depth gauge, submersible pressure
	gauge, timer or watch, and have access to decompression tables
	whenever diving with the dive computer.
WARNING	PERFORM PRE-CHECKS! Always activate and check the device
	before diving in order to ensure that all Liquid Crystal Display
	(LCD) segments are completely displayed, the device has not
	run out of battery power, and that the oxygen, altitude, personal,
	RGBM adjustments, and Safety/Deep Stop are correct.

WARNING	YOU ARE ADVISED TO AVOID FLYING ANY TIME THE COM-
	PUTER COUNTS DOWN THE NO-FLY TIME. ALWAYS ACTIV-
	ATE THE COMPUTER TO CHECK THE REMAINING NO-FLY
	TIME PRIOR TO FLYING! Flying or traveling to a higher altitude
	within the no-fly time can greatly increase the risk of DCI. Review
	the recommendations given by Divers Alert Network (DAN). There
	can never be a flying after diving rule that is guaranteed to com-
	pletely prevent decompression illness!
WARNING	THE DIVE COMPUTER SHOULD NEVER BE TRADED OR
	SHARED BETWEEN USERS WHILE IT IS IN OPERATION! Its
	information will not apply to someone who has not been wearing
	it throughout a dive or sequence of repetitive dives. Its dive profiles
	must match that of the user. If it is left on the surface during any
	dive, the dive computer will give inaccurate information for sub-
	sequent dives. No dive computer can take into account dives
	made without the computer. Thus, any diving activity up to four
	days prior to initial use of the computer may cause misleading
	information and must be avoided.
WARNING	DO NOT EXPOSE ANY PART OF YOUR DIVE COMPUTER TO
	ANY GAS MIX CONTAINING MORE THAN 40% OXYGEN! En-
	riched air with greater oxygen content presents a risk of fire or
	explosion and serious injury or death.

WARNING	THE DIVE COMPUTER WILL NOT ACCEPT FRACTIONAL
	PERCENTAGE 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 decompres-
	sion calculations. If there is a desire to adjust the computer to
	provide more conservative calculations, use the personal adjust-
	ment feature to affect decompression calculations or reduce the
	PO2 setting to affect oxygen exposure according to the entered
	O2% and PO2 values.
WARNING	SET THE CORRECT ALTITUDE ADJUSTMENT MODE! When
	diving at altitudes greater than 300 m/1000 ft, the Altitude Adjust-
	ment 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 3000 m/10000 ft. Failure
	to select the correct Altitude Adjustment setting or diving above
	the maximum altitude limit will result in erroneous dive and plan-
	ning data.

WARNING	SET THE CORRECT PERSONAL ADJUSTMENT MODE!
	Whenever it is believed that factors that tend to increase the
	possibility of DCI exist, it is recommended that you use this option
	to make the calculations more conservative. Failure to select the
	correct Personal Adjustment setting will result in erroneous dive
	and planning data.
WARNING	DO NOT EXCEED THE MAXIMUM ASCENT RATE! Rapid as-
	cents increase the risk of injury. You should always make the
	Mandatory and Recommended Safety Stops after you have ex-
	ceeded the maximum recommended ascent rate. If this Mandatory
	Safety Stop is not completed the decompression model will pen-
	alize your next dive(s).
WARNING	YOUR ACTUAL ASCENT TIME MAY BE LONGER THAN DIS-
	PLAYED 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 decompression stop deeper than at the ceiling
	These factors will also increase the amount of air required to
	reach the surface.

WARNING	NEVER ASCEND ABOVE THE CEILING! You must not ascend
	above the ceiling during your decompression. In order to avoid
	doing so by accident, you should stay somewhat below the ceiling.
WARNING	DO NOT DIVE WITH A CYLINDER OF ENRICHED AIR IF YOU
	HAVE NOT PERSONALLY VERIFIED ITS CONTENTS AND
	ENTERED THE ANALYSIS VALUE INTO YOUR DIVE COM-
	PUTER! Failure to verify cylinder contents and enter the appropri-
	ate O2% into your dive computer will result in incorrect dive
	planning information.
WARNING	DO NOT DIVE WITH A GAS IF YOU HAVE NOT PERSONALLY
	VERIFIED ITS CONTENTS AND ENTERED THE ANALYZED
	VALUE INTO YOUR DIVE COMPUTER! Failure to verify cylinder
	contents and enter the appropriate gas values where applicable
	into your dive computer will result in incorrect dive planning inform-
	ation.
WARNING	Diving with gas mixtures exposes you to risks that are different
	from those associated with diving with standard air. These risks
	are not obvious, and require training to understand and avoid.
	Risks include possible serious injury or death.

WARNING	Traveling to a higher elevation can temporarily cause a change
	in the equilibrium of dissolved nitrogen in the body. It is recom-
	mended that you acclimatize to the new altitude by waiting at
	least three hours before diving.
WARNING	WHEN THE OXYGEN LIMIT FRACTION INDICATES THAT THE
	MAXIMUM LIMIT IS REACHED, YOU MUST IMMEDIATELY
	TAKE ACTION TO REDUCE OXYGEN EXPOSURE. Failure to
	take action to reduce oxygen exposure after the warning is given
	can rapidly increase the risk of oxygen toxicity, injury, or death
WARNING	Suunto also recommends that you receive training in Free diving
	techniques and physiology before conducting breath hold dives.
	No dive computer can replace the need for proper dive training.
	Insufficient or improper training may cause a diver to commit errors
	that may lead to serious injury or death.
WARNING	If there are several divers using the dive computer with wireless
	transmission, always ensure that each diver is using a different
	code before starting the dive.

WARNING	Using the Suunto Dive Planner software is not a substitute for
	proper dive training. Diving with mixed gases has dangers that
	are not familiar to divers diving with air. To dive with trimix, triox,
	heliox and nitrox or all of them, divers must have specialized
	training for the type of diving they are doing.
WARNING	Always use realistic SAC rates and conservative turn pressures
	during dive planning. Overly optimistic or erroneous gas planning
	can result in the exhaustion of breathing gas during decompres-
	sion or in a cave or a wreck.
WARNING	ENSURE THE WATER RESISTANCE OF THE DEVICE! Moisture
	inside the device or battery compartment will seriously damage
	the unit. Only an authorized SUUNTO dealer or distributor should
	do service activities.
NOTE	It is not possible to change between AIR, NITROX and GAUGE
	modes before the instrument has counted down the no-fly time.
	There are, however, exceptions to this: You can change from AIR
	to NITROX mode, as well as from AIR or NITROX mode to
	GAUGE mode even during the no-fly time.
	When planning both air and nitrox dives during the same dive
	series, you should set the instrument in NITROX mode and
	modify the gas mix accordingly.

In GAUGE mode the no-fly time is always 48 hours.

4.2. AC water contacts

The water and data transfer contact is located on the rear of the case. When submerged, the water contact poles are connected by the conductivity of the water and the “AC” symbol appears on the display. The AC text is shown until the water contact deactivates.

AC APPEARS IN THE TOP RIGHT

CORNER OF THE DISPLAY, WHEN THE DIVE

COMPUTER IS IN CONTACT WITH WATER.

THIS ALSO ACTIVATES THE DIVE MODE.

Contamination or dirt on the water contact may prevent this automatic activation. Therefore, it is important that the water contact is kept clean. The contact can be cleaned with fresh water and a soft brush, for example a tooth brush.

4.3. Learning how to use your compass

Suunto Vyper Air integrates a digital compass, which can be used both while diving and on dry land, and can be accessed from either the DIVE mode or TIME mode.

IF ACCESSED FROM TIME MODE,

TIME AND BEARING ARE DISPLAYED AT

THE BOTTOM OF THE SCREEN.

IF ACCESSED FROM DIVE MODE,

CURRENT DEPTH AND TIME OR

MAXIMUM DEPTH, AS WELL AS BEARING

OR DIVE TIME OR TEMPERATURE ARE

DISPLAYED.

NOTE	When accessed from DIVE mode, toggle between the alternative
	displays by pressing the UP/DOWN buttons.

4.3.1. Compass display

The Suunto Vyper Air 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.

4.3.2. Locking a bearing

A bearing can be locked to help you follow a selected course, and directional arrows point towards the locked bearing. The last locked bearing is stored and is available the next time the compass is activated. In the DIVE mode the locked bearings are also stored in the log.

TO LOCK A BEARING,

PRESS SELECT.

The Suunto Vyper Air also provides help for navigating square and triangular patterns, as well as navigating a return heading. This is made possible by following graphical symbols in the center of the compass display:

Table 4.1. Locked bearing symbols

Symbol Explanation

You are traveling towards the locked bearing

You are 90 (or 270) degrees from the locked bearing

Symbol Explanation

You are 180 degrees from the locked bearing

You are 120 (or 240) degrees from the locked bearing

4.3.3. Compass settings

You can define the compass settings (Calibration, Declination and Timeout) in the COMPASS mode:

Calibration

Because of changes in the surrounding magnetic field, the Suunto Vyper Air 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 does not seem to operate properly, or after replacing the dive computer's battery.
