Remove the high pressure (HP) port plug on the first stage of your regulator using
1.
an appropriate tool.
Thread the high pressure transmitter of the Suunto D9tx into the HP port of your
2.
regulator with your fingers. DO NOT OVERTIGHTEN! Maximum torque is 6 Nm/4.4
lbsft or 53 lbsin. The seal is based on a static O-ring, not force!
3.
Attach the regulator to the scuba cylinder and slowly open the valve. Check for
leaks by submerging the regulator first stage in water. If leaks are detected, check
the condition of the O-ring and sealing surfaces.
5.7.2. Pairing and code selection
In order to receive wireless data, the transmitter and the Suunto D9tx need to be
paired. During the pairing procedure, the dive computer locks on the code that the
transmitter has.
The transmitter is activated when the pressure exceeds 15 bar/300 psi and it then
starts sending pressure data together with a code number. During the pairing procedure,
the Suunto dive computer stores the code number and starts displaying pressure
values that are received with that code. This coding procedure prevents data mix-up
from other divers also using a Suunto wireless transmitter.
When there is no stored code, the Suunto D9tx displays "cd:--" and receives data with
lowered sensitivity from a very short distance only (0.1–0.5m / 0.5–1 ft). The flash
symbol is not displayed at this phase. By taking the Suunto D9tx unit close to the
transmitter, it will store the received code and start receiving with full sensitivity and
display data received with this code only.
