SUUNTO D4i - Manual (Page 43)

1. Ensure that the transmitter is properly attached to the regulator’s HP port and
that the regulator is properly attached to the cylinder.
2. Ensure that the Suunto D4i is turned on, and that the wireless integration is en-
abled in the Suunto D4i settings (Tank Press is set ON. For more information,
refer to Section 5.8.3. Setting the tank pressure pairing). If the Suunto D4i is in
the TIME mode, enter the DIVE mode by short-pressing the MODE button. The
D4i should display “cd:--” in the lower left corner of the display.
3. Slowly open the cylinder valve fully and pressurize the system. The transmitter
starts transmitting when the pressure exceeds 15 bar/300 psi.
4. Take the Suunto D4i unit close to the transmitter. The unit will then quickly display
the selected code number and then start displaying the transmitted cylinder
pressure. The wireless transmitter indicator (blinking flash symbol) is displayed
every time the Suunto D4i receives a valid signal.
WARNING
If there are several divers using a Suunto wireless transmitter,
always ensure that each diver is using a different code before
starting the dive.
In case there are several divers using the same code, the transmitter's code must be
changed before diving.
To assign a new transmitter code:
1.
Slowly open the cylinder valve fully to pressurize the system.
2. Immediately close the tank valve, and quickly depressurize the regulator so that
the pressure is reduced to less than 10 bar/145 psi. Wait about 10 seconds, and
slowly open the cylinder valve again to re-pressurize to above 15 bar/300 psi.
The transmitter assigns a new code automatically.
