Equivalent buttons on the MLC 52 and the IR 452
(top half)
6
DVD control buttons — When the DVCM or MLC 52 is in
DVD mode, pressing each of these buttons sends an IR signal
to the DVCM 50 to activate its button with the same label, or to
the MLC 52 to activate its memory block programmed with the
button's command.
7
VCR control buttons — When the DVCM or MLC52 is in VCR
mode, pressing each of these buttons sends an IR signal to the
DVCM 50 to activate its button with the same label, or to the
MLC 52 to activate its memory block that has been programmed
with the button's command.
8
DVD and VCR (mode selection) buttons — Pressing either of
these buttons sends an IR signal to the DVCM 50 to activate the
equivalent mode selection button, or to the MLC 52 to activate
its programmed memory block. This causes the DVCM or
MLC 52 to switch to the selected mode.
For example, if you press the DVD button on the IR 452, the
DVCM or MLC 52 switches to DVD mode. (If it is already in
DVD mode, pressing the IR 452's DVD button has no effect.)
The DVD and VCR buttons are unique in that pressing
them always selects the mode with which they are
labeled.
When the DVCM 50 TV/VCR button is programmed as labeled,
or the command is programmed to an MLC 52 memory block,
pressing the IR 452 TV/VCR button switches the VCR between
TV and VCR modes.
4
Channel button — Pressing the up- or down-arrow on this
rocker button sends an IR signal to either of the following:
The MLC 52 to activate the memory block to which the
channel switch command has been programmed
The DVCM 50 to activate the buttons labeled Tuner
and .
The MLC 52 or DVCM 50 must be in VCR mode. If
they are in DVD mode, this button has no effect. See
Selecting DVD or VCR mode, later in this chapter.
When the DVCM 50 Tuner Up and Down buttons are
programmed as labeled, or the command is programmed to
an MLC 52 memory block, the IR 452 Channel Up and Down
arrow button changes the TV channel to the next higher or
lower channel number.
5
Front Panel buttons — Pressing these buttons (located in the
Front Panel section of the IR 452) sends IR signals to the MLC 52
or to the MLC 104 with the DVCM 50, to activate the buttons on
the MLC's front panel.
The following table shows the functions performed on the
MLC 52 and the MLC 104 (with the DVCM 50) when the
IR 452 Front Panel buttons are pressed (if the MLC buttons are
programmed as pre-labeled).
