Notes

When commands are transmitted serially, keep more than 100 ms intervals between the commands.

Adjustment commands include “ARG” (increase adjustment value) and “ALF” (decrease adjustment value). For usable items (marked “O”), send after the selection command.

The “O” marks in the input source columns indicate that that command can be used. *1 Not possible for PAL/SECAM. *2 Not possible for 480i mode.
