installation instructions for Companion 8.4.3

Express route: everything below can be skipped if you received a (Redeliver) object with your controller. Simply wear it and you will automatically be given a clean copy of the newest version. If you have made changes that you'd like to keep, though, read on! Keep in mind you will still need an updated battery.
  1. Check your current software version by selecting 'about' from the main menu. If it's 8.0.0 or later, you're good to go. If it's older, or you can't even find the 'about' item, contact technical support directly for further assistance. You can also use the command @about to get the same information.
  2. Come to a region with Xanadu support.
  3. Getting ready. Type the following to back up your current list of users: @keychain save
    This is optional if you do not wish to preserve your current users.

    3. Select the Companion_8.4.3 package and upgrade or install it.
    4. If you do not see the update package, see alternative instructions for updating via the command line.
    5. Accept the notecard _System_8.4.2_info when it is offered. If you are running an Aegis that was previously running 8.2.0, there are additional instructions inside that are very important.

    7. Turn the controller back on.
  5. If you do not currently have a HUD at the bottom of your screen, type @setup console. If you already use the HUD, you should have been offered an updated one during the install process.
