Factory defaults
When your MLC 52 is delivered from the factory, or after a reset, the buttons are
set up as shown in the following figures:
Default button configuration — standard MLC 52
Default button configuration — MLC 52 VC
1 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.
