WARNING
Verify the installed transmitter does not physically interfere
with any hoses or other tank assemblies.
7
Use two

in. (16 mm) wrenches to tighten the transmitter,
placing one wrench on the transmitter and one wrench on the
hose fitting.
NOTICE
To prevent damage to the transmitter and possible loss of
function, do not overtighten. Do not use the transmitter
housing to tighten or loosen the transmitter.
Do not grip the regulator or the transmitter to move, carry, or
adjust the tank.
8
Ensure the connection between the transmitter and hose
fitting is secure before using the device.
You must remove the air spool and reinstall the flow restrictor
before installing the transmitter on your tank regulator.
Pairing the Transmitter with a Descent Mk2i Dive
Computer
To pair the transmitter, you must have a pressurized tank and
regulator.
The Descent T1 can transmit air pressure data to a Descent
Mk2i dive computer.
Before you use the transmitter for the first time, you must pair it
with the dive computer. Out of the box, the transmitter is in low
power mode. You must wake the device from low power mode
to complete the pairing process.
NOTE: If a transmitter was packaged with your dive computer,
they are already paired.
1
Install the transmitter on the first-stage regulator (Installing
the Transmitter on Your Tank Regulator, page 5).
2
Gradually open the tank valve to pressurize the first-stage
regulator.
When the transmitter detects pressure, it wakes from low
power mode. The transmitter plays a tone when it wakes
from low power mode and is ready to pair.
3
On the Descent Mk2i dive computer, hold MENU, and select
Dive Setup > Air Integration > Transmitters > Add New.
The dive computer starts searching and displays a list of
nearby transmitters.
4
From the list of transmitters, select the transmitter ID you
want to pair.
The transmitter ID is printed on the housing.
When the pairing process is complete, Connected appears on
the dive computer screen. The transmitter begins sending tank
pressure data, and it is ready to use on a dive. The next time the
transmitter and dive computer are turned on and within wireless
range, they connect automatically when you start a dive.
If you are diving with a group, you can pair up to 5 Descent T1
transmitters with the dive computer.
Selecting Paired Transmitters to View on Your Dive Data
Screens
You can view two paired transmitters at-a-glance on the primary
dive data screen. You can customize which paired transmitters
appear on the screen. By default, the first and second
transmitters that you pair appear.
1
Hold MENU.
2
Select Dive Setup > Air Integration > Display Setup.
3
Select a field to customize.
4
Select a paired transmitter.
Transmitter Settings
You can customize the settings for paired transmitters prior to a
dive.
On the paired Descent dive computer, hold MENU, select Dive
Setup > Air Integration > Transmitters, and select a
transmitter.
Status: Enables a connection to the transmitter, and shows
current connection status.
Identify: Plays a tone on the selected paired transmitter. This
helps you to identify the transmitter without needing to look at
the transmitter ID printed on the transmitter housing.
Units: Sets the pressure units for your tank. The device defaults
to psi if your depth setting is in feet, and bar if your depth
setting is in meters.
Working Pressure: Sets how much pressure the tank has when
full. This value is used to determine the upper end of the
pressure gauge, and to calculate respiratory minute volume
(RMV) for tanks using psi units.
Reserve Pressure: Sets the threshold values for reserve
pressure and critical pressure alerts to appear on the dive
computer.
Volume: Allows you to enter the air volume of the tank. You can
use the Reset Volume option if you move the transmitter to a
different size tank.
NOTE: This value is required to calculate volumetric surface
air consumption (SAC) and respiratory minute volume (RMV)
(Selecting the Gas Consumption Rate Metric, page 7).
SAC/RMV/ATR: Enables the transmitter to be included in
volumetric surface air consumption (SAC), respiratory minute
volume (RMV), and air time remaining (ATR) estimates
(Including Transmitters in Gas Consumption Calculations,
page 7).
Set Transmit Power: Allows you to adjust the power setting if
your transmitter is losing connection with the paired dive
computer underwater.
About: Displays the transmitter ID, software version, and battery
status.
Name: Allows you to enter an easily identifiable name for the
transmitter.
Remove: Allows you to remove a paired transmitter.
