Suunto D9 manual

4.Take the Suunto D9 wrist unit close to the transmitter. The unit will then quickly display the selected code number and then start displaying the transmitted cylinder pressure. A lightning symbol is displayed every time the Suunto D9 receives a valid signal.

WARNING

NOTE

If there are several divers using Suunto D9s with wireless transmission, always ensure that each diver is using a different code before starting the dive.

You can manually change the transmitter’s code by reducing the pressure to less than 10 bar/145 psi and then immediately (within 10-12 seconds) increasing the pressure to above 15 bar/220 psi. The transmitter will then select a new code. The Suunto D9 must be in “cd:--“ mode to pair on the new code. This procedure can be used if, for example, your dive buddy has the same code and you need to change it.

In order to save battery energy, the transmitter shuts off if the pressure remains unchanged for more than 5 minutes, and it will continue transmitting with the saved code when any pressure change is measured.
