SECTION 2 – WARNINGS AND SAFETY MEASURES
NOTE: If you are taking COSMIQ+ on a ight, you MUST turn it off before boarding and
make sure to store it in the pressurized cabin.
1. PLEASE CAREFULLY READ THE ENTIRE CONTENTS OF THE PRODUCT MANUAL BEFORE
USING THE COSMIQ+Dive Computer. Be sure that you fully understand the purpose,
technical functions, settings and limitations of the COSMIQ+Dive Computer before you dive
with it. Failure to do so may cause you to misunderstand the instructions and failure to heed
the warnings and instructions may cause you to engage in behavior that might lead to serious
injury, harm, sickness or even death.
2. THE COSMIQ+Dive Computer IS INTENDED TO BE USED FOR RECREATIONAL AND SPORT
DIVING ONLY. It is not recommended for professional or technical diving, which require
longer dive times and deeper depths than is recommended for recreational sport dives.
Commercial or professional diving may subject the diver to depths and conditions that result
in an increased risk of decompression illness and/or other pressure-related complications.
Therefore, Deepblu strongly advises that the device not be used for any activities other than
recreational/sport diving.
3. ONLY SCUBA DIVERS TRAINED AND CERTIFIED BY AN INTERNATIONALLY ACCREDITED
DIVE AGENCY IN THE APPROPRIATE USE OF SCUBA EQUIPMENT AND TECHNIQUES,
AND WHO ARE FAMILIAR WITH THE USE AND FUNCTIONS OF DIVE COMPUTERS,
SHOULD USE THE COSMIQ+Dive Computer. Using a dive computer is not a substitute for
receiving adequate and proper training. Inadequate or improper training may cause a diver
to engage in behavior that may lead to serious injury or death.
4. ONLY FREEDIVERS TRAINED AND CERTIFIED BY A RECOGNIZED AGENCY IN THE
APPROPRIATE USE OF FREEDIVING TECHNIQUES SHOULD USE THE COSMIQ+Dive
Computer. Using a dive computer is not a substitute for receiving adequate and proper
training. Inadequate or improper training may cause a diver to engage in behavior that may
lead to serious injury or death.
5. USING COSMIQ+DOES NOT REMOVE THE RISK OF DECOMPRESSION ILLNESS (DCI).
The risk of decompression illness may still be present even with a dive prole based on dive
tables or which is deemed safe by a dive computer. COSMIQ+does not take into account
the unique biological characteristics of individual divers, including physiological disposition,
alcohol consumption, dehydration, or use of medication or other drugs, all of which may
cause a diver to be more susceptible to decompression illness. Deepblu strongly advises that
you dive safely within the limits prescribed by dive tables and COSMIQ+, and that you consult
a doctor before diving to determine your tness for diving.
6. THE COSMIQ+Dive Computer DOES NOT REPLACE THE NEED FOR OTHER INSTRUMENTS.
COSMIQ+is intended to supplement the use of other instruments, including a depth gauge,
pressure gauge, timer and watch. Deepblu further recommends that COSMIQ+be used in
conjunction with dive planning based on dive tables.
SECTION 2 – WARNINGS AND SAFETY MEASURES

BACK TO INDEX
7. COSMIQ+IS INTENDED FOR PERSONAL USE ONLY. It is NOT to be shared among divers
during dives or exchanged between two dives in a series. The information displayed applies
only to the diver who has been using it throughout a dive or series of dives, therefore the
recorded information will not be accurate for someone who has not been using it continuously.
8. DO NOT USE COSMIQ+FOR DIVES DEEPER THAN 40 METERS/130 FEET. Deepblu strongly
recommends that divers do not dive below 40 meters/130 feet, the limits for recreational
diving. Doing so greatly increases the risk of oxygen toxicity and decompression illness.
9. ALWAYS ENSURE THE PROPER FUNCTIONING OF COSMIQ+BEFORE DIVING. Before
diving, check the display screen to conrm that information is being displayed clearly. Toggle
between modes to check that it is functioning properly. Additionally, make sure that there is
sufcient battery power to complete your dive. DO NOT dive if the computer’s display is not
clearly visible, if it is frozen in one mode, or if the battery power is low.

feet. This setting can also be adjusted manually using COSMIQ+.
Choose all of your preferred settings while COSMIQ+is in Sync Mode and they will be
automatically uploaded to COSMIQ+. Once the sync is complete, COSMIQ+is ready to use.
4.6 SETTINGS ADJUSTABLE FROM COSMIQ+
Most settings for COSMIQ+can only be adjusted using the Deepblu mobile app. Only a limited
number of settings can be adjusted directly from COSMIQ+. The following settings can be changed
manually using COSMIQ+:
Scuba Mode
• Oxygen level (21% to 40%).
Freedive Mode
• Max Depth Alarm (15 meters/50 feet to 50 meters/165 feet).
• Max Time Alarm (30 seconds to 3 minutes).
To change the above settings, use the MODE button to cycle to the correct operating mode. Press
the ADJUST button repeatedly to adjust the settings. Press the MODE button to save your preferred
settings.
In addition to changing the above settings, the ADJUST button can be used to access the following
functions:
Watch Mode
• Dive Plan function—access projected depth and no-decompression limit for an upcoming dive.
Log Mode
• Toggle between saved dive logs.
To access the Dive Plan and Dive Log functions, use the MODE button to toggle to the correct
operating mode. Use the ADJUST button repeatedly to cycle through items within the mode. Press
the MODE button to exit.
Please see below (Section 5) for a detailed description of each mode, and instructions for adjusting
the settings within the various modes.

4.7 NON-ADJUSTABLE SETTINGS
Please note that the following settings are pre-programmed into COSMIQ+and cannot be changed
at any time:
• Multi-Gas:COSMIQ+does not offer a multi-gas function. COSMIQ+only supports calculations
for Standard Air (21% oxygen) or Nitrox (up to 40% oxygen). If you are planning a multi-gas dive,
DO NOT use COSMIQ+as your primary device.
WARNING: DO NOT ATTEMPT MULTI-GAS DIVING WITH COSMIQ+. COSMIQ+does not have
the capability to support calculations for multi-gas diving and therefore should only be used for
Standard Air or Nitrox dives.
WARNING: ONLY DIVERS WHO HAVE UNDERGONE SPECIALIZED TRAINING FROM AN
ACCREDITED AGENCY SHOULD ATTEMPT MULTI-GAS DIVING. Diving with two or more gases
poses different risks than those of diving with a single gas mixture. To understand and avoid these
risks, divers should undergo proper training from an internationally recognized agency. Failure to do
so can result in errors that can lead to serious injury or death.

SECTION 5 – INSTRUCTIONS FOR USE
5.1 WATCH MODE
The default surface mode for COSMIQ+is Watch Mode. The display screen will enter Standby
automatically after 20 seconds of inactivity in Watch Mode. To turn on the display, press any button.
To navigate to other modes, press the MODE button.
Watch Mode is pre-programmed to display the current time and the current date. You can change
the settings so that COSMIQ+will show the date of your last dive instead of the current date by
accessing COSMIQ+Settings in the Deepblu app.
5.1.1 Dive Plan Function
The Dive Plan function allows you to prepare for an upcoming dive by calculating how long you
can safely remain at various depths without surpassing no-decompression limits and requiring a
decompression stop. As you scroll through the various depths, a corresponding no-decompression
limit will show.
The Dive Plan function can be accessed before your rst dive as well as during a surface interval
between dives. During a surface interval, or within 24 hours of a previous dive, COSMIQ+takes into
account the calculated residual nitrogen levels in your body when determining no-decompression
limits. COSMIQ+also takes into consideration the the percentage of oxygen in the gas you will be
breathing, calculating no-decompression limits based on the percentage of oxygen currently set in
Scuba Mode.
5.1.2 Planning a Dive
To access the Dive Plan function, press the ADJUST button one time if COSMIQ+’s display is in Watch
Mode or two times if it is in Standby. You will hear a beep and the screen will change to show the
word ‘PLAN’ as well as a value for depth and a value for the corresponding no-decompression limit.
When you rst enter the Dive Plan screen the minimum depth displayed is 9 meters/30 feet. It is
visible in the bottom left corner of the display screen. Press the ADJUST button to scroll though
different depths in increments of 1 meter/3 feet. The deepest depth it will display is 40 meters/135
feet. You can hold the ADJUST button to toggle through the depth and time continuously.
The corresponding no-decompression limit is displayed in minutes in the bottom right corner of
the display screen. No-decompression limits will be shorter depending on the presence of residual
nitrogen in your body. COSMIQ+will show a series of three horizontal dashes ( - - - ) instead of a time
value if the no-decompression limit is greater than 300 minutes.
The Dive Plan function will not display depths beyond the no-decompression limit or beyond the
maximum operating depth (MOD). If you reach a depth with a corresponding no-decompression
limit of zero (0), or if a combination of depth and oxygen level exceeds the safe MOD, you will not be
able to scroll further than that depth. The depth will go back to 9 meters/30 feet and start the cycle
again. You should limit your dive plan to depths shallower than the deepest depth that is displayed
in the Dive Plan screen.
SECTION 5 – INSTRUCTIONS FOR USE

18
BACK TO INDEX
When you are nished using the Dive Plan function, press the MODE button at any time to switch
back to Watch Mode.
WARNING: DO NOT PLAN DIVES DEEPER THAN THOSE FOR WHICH COSMIQ+DOES NOT
DISPLAY A NO-DECOMPRESSION LIMIT. Doing so greatly increases your chances of exceeding
no-decompression limits and may cause decompression sickness or central nervous system oxygen
toxicity which can lead to serious injury or death.
5.2 SCUBA MODE
Scuba Mode is meant to be used for scuba diving and not apnea/freediving. It is used to calculate
depth, dive time, water temperature, no-decompression limit, safety stop time and ascent rate.
Additionally, it will calculate the depth and time required for a mandatory decompression stop if the
no-decompression limit is exceeded. You can adjust the settings for the level of oxygen depending
on the type of air mixture in your cylinder.
5.2.1 Preparing to Dive
There are two ways to prepare for a dive in Scuba Mode: water activation or manual activation.
Water activation: If Scuba Mode is your default underwater mode, then simply enter in the water
when COSMIQ+is in Standby or Watch Mode. COSMIQ+will automatically activate Scuba Mode
once you descend past 2 meters/6.5 feet.
Manual activation: Alternatively, navigate to Scuba Mode using the MODE button. Enter the water
and begin descent while in Scuba Mode.
NOTE: On the surface, COSMIQ+refreshes its sensors and captures data at 15 second intervals in
Watch Mode. Therefore, there may be a slight delay between descending below 2 meters/6.5 feet
and Scuba Mode activating. During a dive, the sampling rate for COSMIQ+is 1 second.
5.2.2 Adjusting the Oxygen Settings
COSMIQ+is programmed with a default oxygen level of 21%. You can change the oxygen level
based on the air mixture you will be breathing—Standard Air or Nitrox—with the default being 21%
and the maximum 40%. Oxygen levels have to be set on the surface BEFORE the descent. It is not
possible to adjust the oxygen settings during a dive.
There are two ways to adjust the oxygen settings for COSMIQ+:
1. Using COSMIQ+(see below)
2. Using the Deepblu mobile app (see above section 4.5)
Using COSMIQ+to adjust the oxygen settings:
You can change the oxygen settings on COSMIQ+based on the air mixture in your cylinder before a
dive begins. Remember to always check that the air mixture in your cylinder matches the percentage
input into COSMIQ+.
To change the settings for oxygen level, use the MODE button to enter into Scuba Mode. Once
you are in Scuba Mode, press the ADJUST button to change the oxygen level. The default is 21%
SECTION 5 – INSTRUCTIONS FOR USE

19
BACK TO INDEX
and the maximum amount is 40%. Press the ADJUST button repeatedly to achieve the desired
percentage. You can hold the ADJUST button to toggle continuously.
When you reach the correct percentage, press the MODE button to save your changes and return
to the Scuba Mode screen. The Nitrox icon will be displayed in Scuba Mode when the oxygen
level is set above 21%.
As you adjust the oxygen level, a depth reading will appear in the bottom left corner of the display
screen. This is the corresponding maximum operating depth (MOD) for that paticular oxygen level.
Keep this depth in mind, especially when diving with Nitrox, and do not dive below the MOD.
Diving below the MOD can lead to oxygen poisoning.
Note: The settings for oxygen level remain the same indenitely until you change them. So the
default is 21% and will remain so until you change it. If you make a change to 36% before your rst
dive, it will remain at 36% for your second and third dives unless you change it.
WARNING: ONLY DIVERS WHO HAVE RECEIVED SPECIALIZED TRAINING FROM A RECOGNIZED
AGENCY SHOULD DIVE WITH NITROX. Diving with Nitrox poses risks that are different from those
associated with using Standard Air, and therefore require specialized training in order to understand
and avoid. Nitrox diving without proper training may result in errors that can lead to death or serious
injury.
WARNING: DO NOT CONDUCT A NITROX DIVE WITHOUT FIRST CHECKING YOUR CYLINDER(S)
AND ENTERING THE OXYGEN PERCENTAGE INTO COSMIQ+. Failure to authenticate the contents
of your cylinder and set the appropriate oxygen percentage will cause COSMIQ+to calculate and
display inaccurate information.
5.2.3 Safety Factor
The Safety Factor controls the decompression algorithm COSMIQ+uses to perform decompression
calculations. It allows you to set the level of conservativeness based on your personal preference and
unique risk factors. There are three levels to choose from: Conservative, Normal and Progressive. The
Safety Factor can only be changed through the Deepblu app. Sync COSMIQ+and access COSMIQ+
Settings in the main menu of the Deepblu app to adjust the Safety Factor.
5.2.4 Partial Pressure of Oxygen (PPO2)
COSMIQ+is originally set to a PPO2level of 1.4 bar in order to ensure maximum safety. The PPO2
level is adjustable between 1.2 bar and 1.6 bar, in intervals of 0.1 bar. The PPO2settings can only be
changed through the Deepblu mobile app. Sync COSMIQ+and access COSMIQ+Settings in the
main menu of the Deepblu app to adjust the PPO2level.
5.2.5 During a Dive
When COSMIQ+detects pressure at 2 meters/6.5 feet it will begin recording dive data and calculating
the decompression schedule for the dive. COSMIQ+will lock into Scuba Mode, disabling the MODE
and ADJUST buttons for the duration of the dive. No settings can be changed and no other modes
can be accessed during a dive.
SECTION 5 – INSTRUCTIONS FOR USE

20
BACK TO INDEX
During a dive within the no-decompression limit using Standard Air (21% oxygen) the following
information will be displayed on the screen:
• Current time (Time in hours:minutes)
• Water temperature (Temp in °C/°F)
• Current depth (Depth in meters/feet)
• Deepest depth (Max in meters/feet)
• Dive time (Dive Time in minutes)
• No-decompression limit (No Deco in minutes)
• No-decompression limit bar (graphic bar on right hand side)
• Ascent rate bar (graphic bar on left hand side)
• Safety stop time (seconds) and Stop indicator. This will be shown only once COSMIQ+detects a
depth of between 3–6 meters or 10–20 feet
During a dive within the no-decompression limit using Nitrox (above 21% oxygen) all of the above
information will be shown in addition to the Nitrox icon .
5.2.6 Central Nervous System Oxygen Toxicity
COSMIQ+constantly monitors your exposure to oxygen, by estimating the amount of oxygen in
your body and how it affects your central nervous system (CNS). Your CNS oxygen toxicity level is
calculated in accordance with your exposure to high partial pressure of oxygen (PPO2) levels. It is
represented as a percentage ranging from 0% to 100%. Oxygen toxicity levels reaching 100% are
considered dangerous and should therefore be avoided.
If COSMIQ+ calculates a CNS level of 80%, the alarm will sound. The letters ‘CNS’ will ash on the
screen along with the arrow indicator instructing you to ascend to a shallower depth. The alarm
will become more frequent if you do not ascend to a shallower depth and the calculated CNS level
increases to 85% or higher.
In the case of a CNS alarm, you should conduct a safety stop and end the dive immediately.
WARNING: DO NOT ALLOW YOUR OXYGEN TOXICITY LEVEL TO REACH 100%. Doing so may
cause your body to suffer from convulsions, which can lead to drowning.
5.2.7 Maximum Operating Depth
COSMIQ+also calculates the safe maximum operating depth (MOD)—a depth limit, below which
the PPO2level in the gas mixture you are breathing may become toxic. The MOD is determined
based on both the PPO2limit and the percentage of oxygen you’ve set. Diving below the MOD may
lead to oxygen poisoning and should therefore be avoided.
You can determine your MOD for an upcoming dive by accessing the oxygen setting screen.
Navigate to Scuba Mode and press the ADJUST button. The MOD will be displayed in the bottom
left corner of the display screen. As you change the oxygen level the MOD will change accordingly.
If you dive below the MOD during a dive, the alarm will sound and ‘PO2’ will ash on the screen
along with the arrow indicator instructing you to ascend to a shallower depth. The alarm will continue
to sound until you ascend above the MOD.
