Marlin has different language versions which have different hardware configurations.
The Marlin is now available in Spanish, Japanese, Cantonese and Putonghua versions. Please ensure you have the right language versions prior to your purchase as they are not interchangeable.
Due to hardware limitations, these versions can only be configured to a limited English version that does not have full Swim Smooth integration. The English version, is the only version that supports the full Swim Smooth integration features.
The App will indicate in the device page whether your Marlin is a specific language. The language used in the App will follow the language of the OS of your smartphone/tablet.
