Mares frequently updates its software to improve dive safety and device usability. Updating your Genius computer provides immediate benefits:

If the screen goes blank or freezes mid-update, hold down all four buttons simultaneously for 15 seconds to force a hard reset, then restart the update process.

The process of updating the Mares Genius is straightforward but requires attention to detail. Divers typically use the Mares Dive Organizer software on a PC or the Mac equivalent to interface with the computer via a USB cable. Before initiating an update, it is critical to ensure the battery is fully charged to prevent the device from powering down during the installation, which could potentially corrupt the system. Once connected, the software automatically checks for the latest version and guides the user through the installation process.

The last thing I saw before the lights failed was that eye blinking. Once. Twice. And on the third blink, it winked.

If the screen remains blank or frozen post-update, perform a hard reset by holding down the power button for 15 seconds, or wait for the device to automatically enter sleep mode before waking it up again.
