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.
Installing the Transmitter on a High Pressure
Hose Extension
WARNING
Always use the pre-installed flow restrictor when using the
transmitter directly attached to your regulator (
Transmitter on Your Tank Regulator
). Always use the
included air spool when connecting the transmitter to a high
pressure hose extension. Using the transmitter without either the
flow restrictor or air spool could result in serious injury or death
from an air pressurization failure.
Before you install the transmitter on a high pressure hose
extension certified to the EN 250:2014 standard, you should
read the transmitter position tips and choose a position that
provides the best line of sight to the dive computer.
To install the transmitter, you need two

/
8
in. (16 mm) open-
ended wrenches and a small flat screwdriver or flat-nose pliers.
The transmitter can connect to a high pressure hose extension
from the high pressure output port of the first-stage regulator.
1
Use a screwdriver or pliers to carefully remove the flow
restrictor from the transmitter.
NOTICE
Use care when removing the flow restrictor to avoid
damaging the device.
2
Insert the large end of the air spool into the transmitter.
3
Confirm the regulator is depressurized and detached from a
scuba cylinder.
4
Remove the port plug from the high pressure output port of
the first-stage regulator.
5
Connect a high pressure hose extension to the high pressure
output port of the first-stage regulator.
6
Screw the transmitter onto the high pressure hose extension
until you feel resistance.
WARNING
Verify the installed transmitter does not physically interfere
with any hoses or other tank assemblies.
7
Use two
5
/

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 Compatible
Descent Dive Computer
To pair the transmitter, you must have a pressurized tank and
regulator.
The Descent T1 can transmit air pressure data to a compatible
Descent dive computer. For more information about compatible
dive computer models, go to the Descent T1 product page on
.
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
