Congratulations on your purchase of Merlin 8.
Merlin 8 works with AltaCom II, AltaCom 4x, AltaCom 4xR weatherstations, adding SMS texting to all other Merlin functions and features. You can install Merlin 8 on one computer, you have access to free updates for 3 years.
When you register the SMS function Altalab will send you a license key (this may take up to 24 hours, as it is done by hand). When you paste that key into the Activation tab of the SMS Registration window in ACLive you will be able to activate texting weather and predictions.
