Attaching the Transmitter to Your
Regulator
Upon purchasing the Monitor 3 Air have your Authorized
U.S. Divers Dealer attach the transmitter to your first-stage
regulator. If this is not possible, follow the simple steps
listed below to do it yourself:
Thread the transmitter into the HP port of the
first-stage until finger-tight. Using a
3 /
4
" open-
end wrench, tighten the hose fitting until snug.
DO NOT overtighten.
Attach the first-stage to a charged SCUBA
cylinder. Slowly turn the cylinder valve on-off
handwheel counterclockwise until the valve is
completely open. Submerge the first stage in
water and check for any leaks. If you detect
leaks, take your regulator and transmitter to
your U.S. Divers dealer and have the O-ring
inspected and/or replaced. Then have the U.S.
Divers dealer attach the transmitter to your
regulator.
STEP 1
If your regulator is attached to a charged
SCUBA cylinder, turn the valve handle to the
closed position and vent any air in the regulator
by pressing the second-stage purge button.
Remove the regulator from the cylinder. If you
currently have a gauge attached to your first-
stage regulator, remove it using the appropriate
sized wrench, otherwise remove the high
pressure (HP) port plug from your first-stage
regulator using the appropriate size wrench.
The HP port on all U.S. Divers regulators is
clearly marked with the letters “HP”.
NOTE: The transmitter has 7 /
16
" threads. On
some early model first-stages the HP port is only
3
/
8
". If this is the case with your regulator, you
need to get a
7
/
16
" female to
3
/
8
" male HP
adapter (U.S. Divers part number 1017-85) from
your U.S. Divers dealer.
