SUUNTO HELO2 - Manual (Page 37)

However, if you decide to attach it yourself, do the following:
1.
Remove the high pressure (HP) port plug on the first stage of your regulator using
an appropriate tool.
2. Thread the high pressure transmitter of the Suunto into the HP port of your regu-
lator 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 HelO2 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 computersuunto HelO2 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 HelO2 transmitter.
When there is no stored code, the Suunto HelO2 displays “cd:--” and receives data
with lowered sensitivity from a very short distance only. By taking the Suunto HelO2
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. The code is stored until you
reset it manually.
