The two Display buttons on the MLC are set in the power and macro modes, colored yellow, and labeled On and Off. The Power On and Power Off buttons on the IR 452 are also in power mode and tied to the MLC Display buttons. When you click on an MLC Display button, its equivalent Power button on the IR representation is also selected (surrounded by a yellow box).

These are the only buttons that can be in power mode. You can add commands to them and relabel them, but you cannot change their switch mode or their button mode (macro).

The two buttons in the left column (below the Display On button) are configured differently, depending on the MLC model:

•MLC 52 standard models: These buttons are designated as volume buttons. They are in single switch mode, colored gray, and are labeled Vol Up and Vol Dn. These are the only buttons that can be placed in volume mode. They can also be in input mode or single switch mode.

•MLC 52 VC models: Because the VC models have volume control knobs, volume mode is not available for their buttons. The two buttons in the left column are designated as input buttons. By default they are in input mode, colored blue, and labeled VCR and DVD. They can be placed in single switch mode or input mode only.
