1.0 Introduction
Congratulations on acquiring the new Genesis Graviton dive computer; one of the most versatile,
feature packed and rugged wrist mounted dive computers on the market today.
The Genesis Graviton dive computer was created for recreational scuba divers, who are properly
certified and have basic knowledge of diving physics and diving physiology. This information must have
been acquired during an Open Water diver course or equivalent. Which was administered through a
qualified instructor and sanctioned by a recognized scuba certification agency.
The diver must also be well trained on how to use all scuba equipment components. Neither this
product nor the contents in this manual are a substitute to formal diving education & proper training.
Make sure you have the adequate qualifications before using your dive computer and engage in scuba
diving activities. If you have questions about this product, please contact Genesis Scuba before using it.
All scuba dives carry a risk of injury. Even if you follow any dive computer profile correctly, the dive
computer itself can not anticipate the individual’s own physiology, mental state or physical fitness.
Before engaging in scuba diving activities, you must consult with your physician to ensure you are
cleared to engage in scuba diving activities.
There is no dive computer on the market, dive algorithm, dive table or dive formula that will completely
eliminate the risks associated with scuba diving such as decompression sickness, overexpansion injuries
or oxygen toxicity. Please remember that safety is ultimately your own responsibility.
Please also be sure to read the entire contents of this manual carefully before using your Genesis
Graviton dive computer. Failure to fully understand your dive computer’s operation in relationship with
your dive profiles could result in serious injury. Proper knowledge is required before using your new
Genesis Graviton dive computer.
1.1 Safety Considerations Before Using Your Dive Computer
The Genesis Graviton dive computer was designed for the recreational diver who dives recreational
dive profiles. Dive only at the maximum depth that your training allows and to an absolute
maximum depth of 40m/ 130ft if you are trained for it. Anyone engaged in commercial or technical
diving should be aware that this product is not intended to be used in conjunction with technical or
commercial dive profiles that usually involve deeper depths and prolonged dive times. Genesis
discourages the use of the Graviton dive computer for commercial or technical diving purposes.
Genesis Scuba discourages divers to engage in dives requiring decompression stops. Observe the
NDL (No Decompression Limit) of your dive computer and never let the timer go to 0.0 minutes.
Notice buzzer & vibration, and pay attention to the screen warnings when increasing the ascent
speed, or indications to remain at depth and time.
In the event you exceed NDL Graviton will go into decompression mode, the computer will signal
the diver. The diver must terminate the exploration dive and proceed to an immediate ascent to
the indicated decompression stop before reaching the surface. The ascent speed should never
exceed 30cm/sec / (1 ft. per second) to avoid injuries. Always keep close attention to your ascent
speed & ascend even slower when you approach to the surface.

Redundancy is always good practice in scuba diving. Genesis Scuba encourages the use of additional
depth & time instruments during dives to be able to closely monitor dive profiles and compare
instruments. In the unlikely event your dive computer fails, you’ll have additional backup
instruments to be able to monitor your dive profile and safely ascend to the surface. Consult with
your Genesis dealer for a complete list of redundant instruments you can acquire.
Turn on your Genesis Graviton computer before each dive. Make sure the battery is fully charged
and your settings for either air or nitrox are correct. Additional depth, time, deep stop and safety
stop settings/alarms are also available.
Flying after diving and driving to altitude, which are covered during your Open Water Diver training
or equivalent must also be observed. An airplane icon will be present on the Graviton screen after
each dive and it will remain on the watch’s screen until you are allowed to fly on an airplane or drive
to high altitudes. Please observe this precaution.
Your Genesis Graviton dive computer is intended only to be used either at sea level or at dive sites
where the altitude level does not exceed 3000m / 10,000 ft. OSL (Over Sea Level). Make sure you
check the altitude of all dive sites prior to diving when not at sea level. Incorrect altitude entries will
result on higher risk of decompression sickness due to the decreased atmospheric pressure found at
altitude.
Divers must never exchange dive computers during group diving activities. A dive computer that
was originally used by a particular diver is currently monitoring gas absorption and release the
tissues linked to that particular diver and based on the particular depth and time profiles. Even if
divers in a group were in close proximity that does not ensure the exact depth and time the other
divers performed was the same, let alone during multilevel diving or multiple dives scenarios during
the day. Each diver must provide the means to monitor his/her own depth, time and NDL for each
dive.
If the dive computer was forgotten at the surface and the diver performed a dive without his/her
dive computer, that dive computer should not be used again; only after both the diver and the
computer have spent a complete 24-hour cycle at the surface to ensure full tissue outgassing & the
computer is also free of all previous gas intake / release information. Using that ‘forgotten’ dive
computer again on a subsequent dive will carry a very high risk of decompression injuries as the
profile provided by the computer will be completely inaccurate and will not reflect the real gas
absorbing/releasing timers in the diver.
1.2 Nitrox
Be sure to personally check the oxygen concentration in each cylinder prior to use. If you are
certified to use oxygen enriched air at a concentration higher than 21% (AIR), use the Nitrox
computer settings to enter both the correct EANx mix from the cylinder you are going to use and
adjust the desired PO/ MOD in your Graviton dive computer nitrox settings. If you are not qualified
to use oxygen enriched mixes, use only cylinders that contain air.
The Graviton input value for EANx settings does not accept decimal fractions. If the O2 reading in
the tank label or oximeter is fractional, round up that value. For example, a 32.2% oxygen

5
5
reading enter 32% in the dive computer’s settings. For a 32.5% enter 33%. The 0.5%
fraction will be your tipping point to round up or down. Incorrect O2 entered values will
either underestimate or overestimate the oxygen/nitrogen gradients inside the diver’s
body, affecting both Oxygen toxicity and Nitrogen build up estimations. Again, only dive
with EANx mixes if you are certified to do so.
2.0 Getting Started Guide
2.1 Maintenance
Particularly after using your computer in salt water, soak your dive computer in fresh
water for 5– 10 minutes to dissolve minerals and then rinse it with running fresh water,
but not at very high pressure. Remove it from the water, shake off the excess of water &
wipe it off with a soft cotton cloth or paper towel.
Avoid using any kind of solvent other than fresh water. Solvents may permanently affect
the watch finish and may even affect the seals compromising the computer’s physical
integrity.
Avoid taking apart your dive computer. Opening it or tampering with the internal
components will automatically void your warranty.
2.2 Battery
Your Genesis Graviton dive computer comes equipped with a pre-assembled & sealed
rechargeable lithium battery. Do not attempt to open your dive computer, puncture it,
short the contacts, throw the computer into the fire, expose it to a source of high heat,
high electric current or crush it. The risk of fire or explosion may result if the computer is
tampered with.
Locate the charging clip and charging USB cable provided with your Genesis Graviton dive
computer. Connect the USB cable to any qualified source with an output of 5.0v at 1.0 –
1.5 mAh such as a USB mobile phone charger or a USB outlet from a laptop computer. Do
not use chargers that are not qualified or that you have doubts about the mentioned
voltage and amperage outputs.
Connect the micro USB portion of the cable to the Graviton proprietary charging clip.
At the charging clip, locate the 4 brass colored metal pins. At the Graviton computer,
locate the corresponding connection points, (4 round and chrome-colored contacts) &
make sure they are clean, free of debris, mineral build up or corrosion. Clean the contacts
with denatured alcohol and a cotton swab if needed.
After cleaning, make sure that the charging contacts are free of any water residue and
completely dry before charging, otherwise there will be a risk of electric shock.

6
6
Squeeze the clip to open it & guide it to the watch. Ensure the 4 contact points on the clip
are pointing down and match with the corresponding 4 circular contacts points on the
watch. For reference, if looking at the watch from the top, with the 3 buttons pointing
towards the right, the contacts are located at the bottom of the watch on that same side.
Once the clip is properly connected and charge is flowing, the battery icon, located at the
top of the screen, will display a ‘growing build up motion’ inside the icon. The icon will
display full when the battery is charged completely. Right after that, the computer will turn
itself off.
Separate the clip from the watch when it is fully charged. Depending on how depleted the
battery watch is, full recharge time can vary from one to three hours.
2.3 Storage
After rinsing and drying, store your Genesis Graviton dive computer in a dry, cool place
away from direct sources of high heat, strong electric currents, strong vibrations, excessive
compressing force or at risk of falling off from a high place. Extreme low (below -20°C/ -
4°F) or extreme high temperatures (50°C / 122°F) will also affect your dive computer
internal components.
If the Graviton computer is going to be stored for a long period of time, make sure the
battery charge is at least to 50% (or more preferably). This will ensure that the discharge
rate is slow and the battery does not get depleted completely. Leaving a rechargeable
battery completely depleted for long periods of time will damage it permanently.
2.4. General Considerations Before Using Your Genesis Graviton Dive Computer
This product uses EU-certified non-toxic materials and it is RoHS certified. If any discomfort
is noticed during or after the use of this product, discontinue its use and consult a medical
professional.
This product should not be handled by children under 8 years of age. Junior Open Water
divers, or equivalent based on certification agency, should only handle this computer
under certified diver adult supervision.
For optimal viewing and button access wear your dive computer on the wrist you normally
wear a wrist watch, you may even want to use it as your daily watch going forward.
Make sure you confirm that the computer has sufficient battery charge and adjust all your
desired settings before entering the water and confirm that all the pre-dive information is
displayed on the screen before the dive.
The Genesis Graviton compass & time zone settings feature a GPS antenna that is hidden
under the screen and it is recommended to keep the antenna pointing up toward the sky
when calibrating the compass or setting time for a better signal.

2.5. Force Shutdown & Turning ON From Shutdown mode
Your Genesis Graviton features a Force Shutdown mode that assists in conserving battery
power. When your Genesis Graviton is on Time Mode, just press and hold the Power Button
(Fig#1 Button #2) in the lower left corner for about 15 to 20 seconds, the Graviton will force
the shutdown, to re-initiate press the Power Button again for 5 seconds to start normally. If
the watch does not respond, it is possible that your Graviton has run out of battery power,
please attach the charging clip to your watch and charge it for about 5 minutes before trying
again.
If there is any information you’ve read in this manual that you do not fully understand,
contact your local Genesis retailer and ask all the necessary questions. Additionally, you
