    INTRODUCTION Welcome to Beuchat and thank you for choosing the VOYAGER 2G ! It is extremely important that you read this Operating Manual in sequence and understand it completely before attempting to use the VOYAGER 2G as a dive computer.

  • Page 10: Operating Modes

    OPERATING MODES The VOYAGER 2G features 3 Operating Modes, NORM (Fig. 1A) which is used for Air and Nitrox SCUBA dives, GAUG (Fig. 1B) used for SCUBA dives in which Nitrogen-Oxygen calcula- tions are not performed, and FREE (Fig. 2) used for breath hold activities that do not use SCUBA.
  • Page 11 Situations that will activate the NORM/GAUG 10 second Alarm include - • Descent deeper than the Depth value set. • Dive Time Remaining decreases to the value set. • Elapsed Dive Time reaches to the value set. • PO2 reaches to the value set. •...

    • FREE Dive NiBG Alarm (Caution zone, 7 segments) - 3 beeps 3 times. • Entry into Deco during a FREE Dive (Permanent Violation) - 3 beeps 3 times. • Free Dive Mode Countdown Timer reaches 0:00 - each 3 beeps 3 times. During the following NORM Dive situations, the 10 second continuous tone will be fol- lowed by a 5 second steady beep that will not turn off when acknowledged - •...

  • Page 13: Power Supply

    POWER SUPPLY The VOYAGER 2G uses (1) 3 volt CR2450 Lithium Battery which should maintain operation for 1 year or 300 dive hours if 2 dives are conducted during each dive period. The VOYAGER 2G checks battery voltage every 2 minutes while on the surface. •...

  • Page 16: Bar Graphs

    BAR GRAPHS The VOYAGER 2G features 3 Bar Graphs >> NiBG, O2BG, and ASC. NiBG (Nitrogen Loading Bar Graph) The NiBG (Fig. 6a) represents tissue loading of nitrogen, show- ing your relative no decompression or decompression status. As your depth and elapsed dive time increase, segments will add to the NiBG, and as you ascend to shallower depths, the segments will recede, indicating that additional no decompression time is allowed for multilevel diving.
  • Page 17 O2BG (Oxygen Bar Graph) The O2BG (Fig. 7a) represents oxygen loading, showing the maximum of either per dive accumulated oxygen, or 24 hour period accumulated oxygen. As your oxygen exposure (accumulation) increases during the dive, segments will add to the O2BG, and as saturation decreas- es, it will begin to recede indicating that additional exposure is Fig.

  • Page 46: Deco Dive Time Remaining (Ndc)

    NO DECO DIVE TIME REMAINING (NDC) NDC is the maximum amount of time that you can stay at your present Depth before entering a Decompression situation. It is calculated based on the amount of Nitrogen absorbed by hypo- thetical tissue compartments. The rates each of these compartments absorb and release Nitrogen is mathematically modeled and compared against a maximum allowable Nitrogen level.

    If O2 reaches 100% of the allowed limit (300 OTU), the O2 icon will replace NO DEC. High O2 is described later. ASCENT RATE INDICATOR (ASC) The ASC shows how fast you are ascending.

  • Page 51: No Deco Safety Stop (Ss)

    No Deco Safety Stop (SS) Upon ascending to 6 M (20 FT) for 1 second on No Deco dives in which Depth exceeded 9 M (30 FT), a Safety Stop screen will appear (if set On) displaying a recommended Stop at 4,5 M (15 FT) with a Timer that counts down from 3:00 to :00 (min:sec).
  • Page 52 In the event that you descend below 9 M (30 FT) for more than 10 seconds during the countdown or the countdown reaches :00, the No Deco Main will be displayed. The SS Main will reappear upon ascent again to 6 M (20 FT). If you enter Deco during the dive, the SS will be disabled for the remainder of that dive.

    CAUTIONARY MODES...

  • Page 54: Decompression

    DECOMPRESSION Decompression mode activates when theoretical No Decompres- sion time and depth limits (NDLs) are exceeded. Upon Entry into Decompression, the Audible will sound until acknowledged or for 10 seconds during which the STOP icon, DEC icon, and full NBG will flash to alert you. Upon entry into Deco, the Deep Stop and Safety Stop features are disabled for the remainder of that dive, even when the Deco obligation is complete and No Deco status is regained.
  • Page 55 To fulfill your deco obligation, you should make a safe controlled ascent to a depth slightly deeper than the Stop Depth indicated and decompress for the Time indicated. The amount of decompression credit time that you receive is dependent on Depth, with slightly less credit given the deeper you are below the Stop Depth indicated.

  • Page 56: Conditional Violation (Cv)

    CONDITIONAL VIOLATION (CV) If you ascend shallower than the calculated Deco Stop Depth, the Audible will sound, and no off gassing credit will be given, until you descend below the Stop Depth. If you descend below the required Stop Depth before 5 minutes have elapsed, operation will continue to function in Deco and off gassing credit will resume.

  • Page 57: Delayed Violation 1 (Dv1)

    Upon entry into the following Violation modes, the Audible will sound, even if set Off. When these events occur, the alarm cannot be acknowl- edged/silenced by pressing S. DELAYED VIOLATION 1 (DV1) If you remain above a required Deco Stop Depth more than 5 minutes, operation will enter DV1 which is a continuation of CV.

  • Page 58: Delayed Violation 2 (Dv2)

    DELAYED VIOLATION 2 (DV2) If the Decompression obligation requires a Stop Depth between 18 and 21 M (60 and 70 FT), the STOP icon, DEC icon, and full NBG will flash until the required Stop Depth is 18 M (60 FT). When this occurs, you must make a controlled ascent to just deeper than, and stay as close as possible to, 18 M (60 FT) until the Deco Stop Depth indicates 15,0 M (50 FT), etc., then you...

  • Page 59: Delayed Violation 3 (Dv3)

    DELAYED VIOLATION #3 (DV3) If you descend deeper than the MOD (Max Operating Depth) of 120 M (400 FT), the Audible will sound for 10 seconds, and Current Depth will display 3 dashes ( - - - ) flashing signifying that you are out of range (deeper than the unit's ability to predict ascents or accurately perform calculations).

  • Page 60: Violation Gauge Mode (Vgm)

    VIOLATION GAUGE MODE (VGM) If calculations require a Deco Stop Depth greater than 21 M (70 FT), or if Deco is entered while operating in FREE Mode (described later), operation will enter Violation Gauge Mode (VGM) for the remainder of that dive and for 24 hours after surfacing.
  • Page 61 The VOYAGER 2G will also enter VGM 5 minutes surfacing from a dive in which a Delayed Violation (1, 2, or 3) occurred. Once on the surface, VGM blocks access to the Set F, Plan, Fly, and Sat features/screens. The timer that appears when you access Fly is to inform you of time remaining before normal operation can resume with full features and functions.

  • Page 87 ADDITIONAL INFORMATION PERTAINING TO FREE DIVE MODE Although breathing apparatus is not utilized for Free Dive activities, nitrogen tissue loading remains a factor. Nitrogen loading is calculated based upon a fixed FO2 of Air. Since a user has the option of alternating between NORM (SCUBA) and Free Dive activities within a 24 hour period, nitrogen calcula- tions and the displayed value of NDC Time are carried over from one operating mode to the other, which permits the user to maintain awareness of nitrogen absorption and off gassing status.

The VOYAGER 2G was not designed to make decisions for you, only to provide you with the information you need to make responsible decisions for yourself. This begins with a dive Plan that will help you avoid a low air or decompression situation.

    ALTITUDE SENSING AND ADJUSTMENT Prior to the first dive of a series of repetitive dives, Altitude (i.e., Ambient Pressure) is mea- sured upon activation and every 15 minutes until a dive is made. > While it is operating in Surface mode after a dive, measurements are taken every 15 minutes during the 24 hour period after surfacing.

    When the Conservative Factor feature is set On, allowable dive times are calculated based upon the next higher 915 meter (3000 foot) Altitude. All adjustments for Altitudes higher than 3355 meters (11000 feet) are then made to allowable dive times for 4270 meters (14000 feet).
