NOTE: Installing Nor150 version: Copy Service pack and application package to a USB dongle. If a new license is needed: Copy License.txt to the same USB dongle (see description above). Connect the USB dongle to your Nor150 instrument and power the instrument. Follow the instructions in the installation process. Please Note! Instrument with SW version 1.0 or power controller version 1.0 or lower, needs to be shipped to Norway for upgrade. Version 1.2 will not install on these devices because they need a manual upgrade of the power controller. License system: When upgrading from v1.2 or earlier you will need a license key. The license key is a text file License.txt, which is supplied from Norsonic. Please send a request to support@norsonic.com, with the instrument ID (found in SETUP/Instrument/About menu) and the needed options (see attached document) and you will receive an e-mail with the License.txt file. To activate the license in Nor150, either have the file available at the USB dongle during the installation process, or enter it manually after the installation: Copy the license file to a USB dongle, go to SETUP/Instrument/About/Licenses and press “Enter license”.
