Your G300 system should always be running on the latest version of the operating firmware. By default, you will receive alerts when there are new firmware updates, but you can check to see if you're running the latest version by clicking the Setup tab and then selecting Firmware.
When you perform firmware upgrade, you have the option to preserve your G300's current settings, so you won't have to change anything after the upgrade.
You can also give your G300 unit a specific name, which is useful if there is more than one system in the house, or if you have multiple G300 units in different places.
