Your SABRE reader may need to be calibrated for your environment to ensure the best possible performance. Calibration of the reader attempts to determine the strength of the signal available at a 1M range, taking into account environmental factors. Calibration can be run during the SABRE registration process or at any time by opening the configuration page from the Admin Installer tab within the Safetrust Wallet application. Please note that you must have either the “Installer” or “Admin” role in order to view the Admin Installer tab.
