Additional Feature Benefits for D9tx, D6i and D4i - Software v1.2.9
Addition of DIVE mode OFF and FREE
Addition of Apnea timer
D6i upgraded from 2 to 3 nitrox mixes per dive
Remaining airtime display added to D9tx (already in D6i D4i)
Ability to switch Remaining air time display ON or OFF
Improved time alarm functions - Off/Once/Weekdays/Everyday
Logbook Memory - VERY IMPORTANT!
The logbook remains intact after the update on the D9tx and D4i and will be unaffected.
However, D6i logs will be ERASED by the update as there is an additional 3rd gas mix option being added to the D6i software. Therefore, it is extremely important that the customer downloads any required information before sending the D6i in for update. The total dive summary will still be shown in history. For customers using DM4 they should also update to the latest version after the update.
