On GT-1000 units running system program version 2.xx or earlier, the OUTPUT SELECT settings USER1 and USER2 were used to load GT-1000 AIRD Output Select Library data (seven types).
From system program version 3.00 onward, all seven types of AIRD Output Select Library data are pre-installed. The same applies to the GT-1000CORE (all versions). USER1 and USER2 are therefore no longer needed for this purpose.
If your GT-1000 is running a version earlier than 3.00, updating to the latest system program is recommended.
