Dive Warnings
WARNING
• This device is for use by certified divers only.
• This device should not be used as the only source of
pressure information. Always use backup instruments,
including a depth gauge, submersible pressure gauge, and
timer or watch.
• Make sure that you fully understand the use, displays, and
limitations of your device. If you have questions about this
manual or the device, always resolve any discrepancies or
confusion before diving with the device. Always remember
that you are responsible for your own safety.
• The dive computer can calculate your surface air
consumption rate (SAC) and air time remaining (ATR). These
calculations are an estimate and should not be relied on as
the only source of information.
• Perform pre-dive safety checks, such as checking proper
device function and settings, display function, battery level,
tank pressure, and bubble checks to check hoses for leaks.
• If a tank pressure warning or battery warning appears on the
dive computer, terminate the dive immediately and safely
return to the surface. Disregarding the alarm may result in
serious injury or death.
• For safety reasons, you should never dive alone. Dive with a
designated buddy. You should also stay with others for an
extended time after a dive, because the potential onset of
decompression sickness (DCS) may be delayed or triggered
by surface activities.
• This device is not intended for commercial or professional
dive activities. It is for recreational purposes only.
Commercial or professional dive activities can expose the
user to extreme depths or conditions that increase the risk of
DCS.
• The transmitter is not an oxygen cleaned product. Do not use
the transmitter with anything greater than 40% oxygen.
Starting a Dive on a Paired Descent Dive
Computer
1
On the paired Descent dive computer, press START from the
watch face.
2
Select a dive mode.
See the owner's manual for your Descent dive computer for
more information about supported dive modes.
3
Press START until the primary dive data screen appears.
The primary dive data screen displays up to two paired
transmitters (Selecting Paired Transmitters to View on
Your Dive Data Screens, page 3).
NOTE: You can use this screen to confirm your paired
transmitters are connected to your dive computer prior to
starting your dive.
4
Descend to start your dive.
The activity timer starts automatically when you reach a
depth of 1.2 m (4 ft.).
5
Press DOWN to scroll through the additional data screens.
When you return to the surface, the device automatically ends
and saves the dive after one minute has elapsed (by default).
You must depressurize your regulator to return the transmitter to
low power mode.
Viewing the Transmitter Data Screens
1
During a dive, press DOWN on your paired Descent dive
computer to view the transmitter data screen.
The gas consumption estimate for the selected transmitters.
NOTE: You can customize the transmitters used for gas
calculations (Including Transmitters in Gas Consumption
Calculations, page 3).
The air time remaining (ATR) estimate for the selected
transmitters.
Your primary and secondary transmitters and their tank
pressure values.
NOTE: You can customize which transmitters are displayed
(Selecting Paired Transmitters to View on Your Dive Data
Screens, page 3).
2
From the transmitter data screen, press START to view
additional paired transmitters in the network.
