Selecting DVD or VCR mode

The DVD and VCR buttons on the IR 452 are different from its
other buttons in that each contains a permanent mode switch
command. This command is sent to the DVCM 50, which
activates its equivalent button, or to the MLC 52, which activates
its programmed memory block, every time the button is
pressed. Regardless of any programming done to the DVD and
VCR buttons on the DVCM 50, pressing these IR 452 buttons
always causes the DVCM or MLC 52 to switch to the mode of
the button that was pressed.

If the DVCM 50 or MLC 52 is in VCR mode and you press
the IR 452's DVD button, the controller switches to DVD
mode. (If it was already in DVD mode, no switch occurs.)
If the DVCM or MLC 52 is in DVD mode and you press
the VCR button on the IR 452, the controller switches to
VCR mode. (If it was in VCR mode, no switch occurs.)

If additional commands have been programmed on the

DVCM 50's DVD or VCR button, these commands also
are issued when the IR 452 DVD/VCR button is pressed.

To issue a command from the IR 452 to a DVD player or a
VCR, you must fi rst press the button to select the appropriate
operating mode, as described below.
