MAIN REMOTE CONTROL FUNCTIONS

IMPORTANT NOTE:

The AVR 645’s remote may

be programmed to control up to thirteen devices,
including the AVR 645. Before using the remote,
it is important to remember to press the

Input

Selector Button

that corresponds to the unit

you wish to operate. In addition, the AVR 645’s
remote is shipped from the factory to operate the
AVR 645 and most Harman Kardon CD or DVD
players and cassette decks. The remote is also
capable of operating a wide variety of other products
using the control codes that are part of the remote.
Before using the remote with other products, follow
the instructions on pages 48–51 to program the
proper codes for the products in your system.

It is also important to remember that many of the
buttons on the remote take on different functions,
depending on the product selected using the

Input

Selectors

. The descriptions shown here primarily

detail the functions of the remote when it is used to
operate the AVR 645.

Power Off Button:

Press this button to place

the AVR 645 or a selected device in the Standby
mode. Note that this will turn off the main room
functions, but if the Multiroom system is activated,
it will continue to function.

Power On Button:

Press this button to turn on

the power to a device selected by first pressing one of
the

Input Selectors

LCD Information Display:

This two-line screen

displays various information, depending on the com-
mands that have been entered into the remote.

Input Selectors:

Pressing one of these buttons

will perform three actions at the same time. First, if the
AVR 645 is not turned on, this will power up the unit.
Next, it will select the source shown on the button as
the input to the AVR 645. Finally, it will change the
remote control so that it controls the device selected.

The buttons labeled DVD, DMP, XM and HDMI 1 are
each used to select either of two input sources:

• The first press of the DVD Button selects the compo-

nent connected to the DVD inputs. A second press
of this button selects the component connected to
the CD inputs.

• The first press of the button labeled DMP selects

The Bridge as the input. A second press of this button
selects the device connected to the Tape inputs.

• The first press of the XM button selects XM Radio

as the input. A second press selects the source
connected to the USB jack as the input.

• The first press of the HDMI 1 button selects the

device that is connected to the HDMI 1 jack.
A second press selects the device connected to
the HDMI 2 jack.

In normal operation, the remote will revert to control-
ling the AVR when no button is pressed for 6 seconds.
This allows the remote to automatically return to con-
trol of important functions such as volume, mute and
surround mode selection after you have used the
remote to control another device. If you wish to
change the length of time that the remote operates
another device, or to have the remote remain active
for control of the other device (such as a DVD player
or set-top box) until you manually return control to the
AVR by pressing the

AVR Selector

, follow the

instructions on page 57.

AVR Selector:

Pressing this button will switch the

remote so that it will operate the AVR 645’s functions. If
the AVR 645 is in the Standby mode, it will also turn the
AVR 645 on.

Test Button:

Press this button to begin the

sequence used to manually calibrate the AVR 645’s
output levels. (See page 33 for more information on
manually calibrating the AVR 645.)

DSP Surround Mode Selector:

Press this

button to select one of the DSP surround modes, such
as Hall 1, Hall 2 or Theater. Each press of the button
selects another mode. (See page 60 for more infor-
mation on surround modes.)

Logic 7 Mode Select Button:

Press this button

to select from among the available Logic 7 surround
modes. (See page 60 for available Logic 7 options.)

Direct Button:

Press this button when the tuner

is in use to start the sequence for direct entry of a
station’s frequency. After pressing the button, simply
press the proper

Numeric Keys

to select a

station. (See page 41 for more information on the tuner.)

Clear Button:

When programming the remote

or using the EzSet feature, press this button to cancel
the current function. When using the remote to enter
frequencies for direct tuner access, press this button
to clear previous entries.

EzSet/EQ Button:

Press this button to turn the

filters used by EzSet/EQ on or off. This allows you to hear
the difference in system performance when EzSet/EQ is
engaged or out of the signal path.

Tuning Mode Button:

When using listening to

AM or FM stations, press this button to change the
tuner mode between manual and automatic. When the
button is pressed so that

AUTO/STEREO

appears in the

Upper Display Line

and in the

on-screen display, only stations with acceptable signal
quality will be tuned, and the tuner will play FM sta-
tions in stereo, when available. In the

AUTO

mode,

when the

Tuning Up/Down Buttons

are pressed, the unit will automatically search for the
next available station with good signal strength. When
this button is pressed so that

MANUAL/MONO

appears in the

Upper Display Line

and in the

on-screen display, each press of the

Tuning Up/Down

Buttons

will move the frequency up or

down in single-step increments. When the FM band is
in use, pressing the button so that the

MANUAL

mode is activated will enable you to tune stations with
weak signals by changing to monaural reception. (See
page 41 for more information on AM/FM tuner opera-
tion.) When listing to XM Radio, press this button to
scroll through the following display options for the

Lower Display Line
