Setting change during the dive

To navigate this menu follow the instructions shown in the picture on the left

 MODE: 

OC/CCR (only for iX3M Tech+ and iX3M Reb)

 

MIX: Mix 

percentage %O2/%He and mix’ status.

   

ACT

: Mix that we are currently breathing 

   

YES

: Active mix but that we are not currently breathing

   

NO

: Deactivated mix

 

GFL/GFH (R0 se VPM): 

It modifies the gradients Low and High if BUL or the 

 

 

 

 

 

     Critical Bubble radius if VPM.

 

 

 

 

 

    (if iX3M Deep PS: if modifies the conservatism level)

Press button  any time to save the modifications and go back to the Dive mode .

To know how to modify the parametres MIX and GFL/GFH (R0)(PS) make reference 

to the section DIVE SET of this manual.

Attention

: in the following pages we will explain how to modify the MIX and 

the algorithm settings during the dive. 

However remember always that: 

To modify the Gradients and the Critical Bubble Radius a suitable training is 
necessary!

To use more than one Mix when diving a suitable training is necessary!

DO NOT modify these parametres if you have not received such training!
