M2 USER MANUAL
In order for the M2 to display the pressure
signal from a Smart transmitter, a coded,
interference-free line of communication has
to be established first. This step needs to be
performed only once for each transmitter.
To pair the M2 to a transmitter, proceed as
follows:
- Mount the first stage regulator with the
Smart transmitter attached on a full tank.
- Set the M2 to pairing mode (SCUBA
-> gas -> pairing) and place it near the
transmitter.
- Open the tank valve.
Upon pressurization, the Smart transmitter
sends a pairing sequence to the M2. When
the M2 receives this information, you may
select the tank designations (T1, T2, etc.).
Tank T1 is always the main tank you start
the dive with. Other tanks are used for
diving with more than one gas mixture,
described in section
Diving with 2 or
more gas mixture
.
Use the +/UP or -/DOWN buttons to select
the tank that you want to assign to the
transmitter, then press SEL. The current
pressure of the paired tank will appear on
the top row.
F
NOTE: The transmitter must have
been unpressurized for at least 40
seconds prior to the pairing operation;
otherwise, it will not transmit the
pairing sequence.
A transmitter can only be paired to
one tank designation. If you pair the
same transmitter to a second tank
designation, the first one will be erased.
After a successful pairing of T1 to the M2,
the SCUBA mode display will show the
tank pressure in either BAR or PSI. If T1
has been paired but the M2 is not receiving
any signal, it will show “- - - “ instead of a
pressure value.
F
NOTE: The Smart transmitter has a
signal range of approximately 1.5m/5ft.
To maximize the life of the battery, the
transmitter turns itself to a low update
rate when there is no pressure change
for more than 40 seconds. It also
turns itself off when the pressure is
14bar/200psi or less.
If a transmitter battery is weak, the
M2 alerts you in SCUBA mode with
a display screen alternating for 10
seconds between message T1/T2/Td
BATT and the normal display.
Battery replacement procedure can be
found in section
Replacing the battery in
M2 and transmitter
.
If you have paired more tanks (T2 and/or
Td) and they are active (content is selected),
you can review the pressures via the gas
summary by pressing and holding the -/
DOWN button on the Dive mode display.
