You can use the imported content on the V71, V51, or V31 without authenticating your membership via Wi-Fi until you have turned the power on and off 50 consecutive times.
When the following message appears, please connect to Wi-Fi to authenticate your membership. See also the related article "The error message "(X) Warning Unable to verify your Roland Cloud membership" Appeared and the imported Instrument Expansions are disabled."
If you frequently use the V71, V51, or V31 in an environment without network access, we recommend purchasing a Lifetime Key for the Instrument Expansions through Roland Cloud Manager.
