Our products are all CE, FCC and ARIB certified for use on the licence free RF channels in those regions. You can find a full break down of the countries covered by those certifications, and the legal RF channels in those regions here.
If you bought your device in one region but wish to use it one of the other certified regions, you simply need to change the RF country/area in your unit’s System Setting. This will automatically select the legal, licence free RF channels for that region. Due to certification regulations in some areas, this option may be locked out on your device. Please email email@example.com if that is the case.
