5.8.2. Pairing and code selection
In order toreceive wirelessdata, thetransmitter andthe SuuntoD9 needto bepaired.
During the pairing procedure, the transmitter and dive computer select a common
transmission code.
The transmitter is activated when the pressure exceeds 15bar/218 psi and it then
starts sending pressuredata togetherwith a codenumber. During thepairing procedure,
the Suunto D9 stores the code number and starts displaying pressure values that are
received with that code. This coding procedure inhibits data mix-up from other divers
also using a Suunto D9 transmitter.
When there is no stored code, the Suunto D9 displays “cd:--” and receives data with
lowered sensitivity from a very short distance only. By taking the Suunto D9 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 for approximately
two hours, or until the cylinder pressure falls below 10 bar/145 psi. The set code can
also be manually erased.
To pair the transmitter and the Suunto D9 dive computer:
1.
Make sure that the transmitteris properly attached to the regulator’s HP port and
that the regulator is properly attached to the cylinder.
2.
Ensure that theSuunto D9 isturned on,and that thewireless integrationis enabled
in the Suunto D9’s settings (HP set ON, see SECTION 5.9.10). The D9 should
display “cd:--” in the lower left corner of the alternative display.
3.
Slowly open the cylinder valve fully and pressurize the regulator. The transmitter
starts transmitting when the pressure exceeds 15 bar/218 psi.
