To recharge the RATIO iX3M 2 we recommend to use a USB wall charger (like the one of your mobile/tablet).
If you decide to use a PC USB plug (deprecated), make sure that the PC doesn’t interrupt the electricity flow once in stand-by.
Even if the RATIO iX3M 2 has a new generation battery without memory effect, we recommend to recharge the battery
completely.
The average recharge time is 4-5 hours depending on the residual charge level.
Attention: It is suggested to not dive if the computer shows <30% of battery.
Do not dive if the computer shows <20% battery.
When connecting the USB cable to recharge the device, the symbol => will appear in the watch screen within 45 seconds.
It means that recharging procedure is in progress. When the recharge is finished the symbol => will disappear.
Once the battery charge is finished, even if the device remains connected to the plug, the computer automatically
interrupts the electricity flow. In case the device is left in charge more than necessary (e.g. all night
long), you could find it switched off. You can check the computer charge level pressing any button; the
battery percentage can be visualized on the screen’s left upper corner.
If the device is in charge and no button is pressed for more than 10 minutes, the back light is reduced
to the minimum, to allow a faster recharge cycle.
If the recharge cycle is not completed, the battery indicator might not be precise until the next complete
recharge cycle is carried out.
Attention: Do not leave the iX3M 2 completely without charge (0%) for a long period (e.g. 1-2
months). This may damage the battery. The iX3M 2 registers an alarm if left without charge for
long time. This event is not covered by warranty.
