SUUNTO HELO2 - Manual (Page 39)

After this, the transmitter selects a new code. The Suunto HelO2 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.
NOTE
In order to save battery energy, the transmitter enters power
saving mode with slower data transmission rate if the tank pres-
sure remains unchanged for more than five (5) minutes. The
transmitter continues transmitting with the saved code when any
pressure change is measured.
5.7.3. Transmitting data
After the pairing procedure, the Suunto HelO2 will receive cylinder pressure data from
the transmitter. The pressure is displayed in either bars or psi, depending on the unit
selected. Any time the Suunto HelO2 receives an appropriate signal, the wireless
transmitter indicator is displayed in the lower left corner.
