Marantz RC5400 - Manual (Page 15)

You can operate the devices using two kinds of buttons;
Soft buttons - Virtual buttons on the Touch Screen.
Hard buttons - Seven buttons below the screen (HOME, Left
and Right Function buttons are not included) and five to the right
of the screen (Vol +/-, Ch Up/Down & Mute)
Using the Soft Buttons
By tapping the Soft buttons on the Touch Screen you send
Infrared (IR) commands to the device you have selected.
The name of the device you are controlling is always displayed on
the DEVICE OVERVIEW button.
Sending commands
IR commands are invisible. However, when you send a command,
an animated icon appears in the INFO button at the UPPER TOOL
BAR to show that a command is being sent.
Using the Hard Buttons
Hard buttons can be operated at any time, even without turning on
the Touch Screen. They can change their function depending on
which device is active (teach commands to the specific device).
For example:
Since VOLUME Up, VOLUME Down and MUTE are typically
receiver/preamp commands in most home theaters, these direct access
buttons have been pre-programmed to always operate a Marantz
receiver/preamp as the default. Should you own another brand, see the
programming instructions on page 28-29.
MENU, ENTER, EXIT, 4-Way Cursor Navigation, CHANNEL Up and
CHANNEL Down are typically programmed to change with the device
selected. So when you are operating your DVD player, you use them to
navigate DVD menus and change chapters. While you are watching
TV, the MENU buttons operate the TV menus and the CHANNEL
buttons change channels.
