OPERATION

it will appear; or press the button again until XM
Radio is heard. Press the

Tuning Selector

to change stations within a frequency band. Press
the

Tuning Selector

to select a different

XM channel.

• From the main remote, press the

Tuner/FM Select

Button

by pressing the button up towards the

top of the remote as needed until XM Radio is
shown as the source. To change stations, press the

Tuning Up/Down Button

• To select the tuner from the ZR 10 remote control,

press the

XM Radio Selector Button

Channels are selected using the

Prev/Next

Transport Controls

While using XM Radio is similar in many ways to
AM/FM terrestrial radio, the wide range of program
choices available, as well as the ability of the XM serv-
ice to add special data and information tags into the
digital audio data stream, means that some of the
front-panel and remote controls traditionally used
for tuner operation have different functions with
XM Radio.

• When XM Radio is the AVR’s source, the channel

number will appear in the

Upper Display Line

along with an indication of the Preset number, if any,
and a series of bars at the far right end of the dis-
play. These bars (not shown in the semi-OSD mes-
sage), show the current signal strength similar to the
signal strength displays on a cellular phone.

• The current channel’s name will normally appear in

the

Lower Display Line

. For local traffic infor-

mation, the name of a city will be shown in place of
the channel name. You may change this display to
show the current artist and track title information by
pressing the

Tuning Mode Selector

When you are listening to a channel with local traffic
information in the “200” series of channel numbers,
these buttons change the display to show the tem-
perature and current weather for the selected city.

• To tune a channel number directly, simply press the

Numeric Keys

. Unlike standard AM/FM

tuner operation, it is not necessary to press the
Direct button first.

• The AVR 645 has five banks of preset memories

for XM Radio, each with eight memory positions
and designated by a letter (“A” through “E”). To
store a channel into a memory group, first press
the

Set Button

until

PRESET

appears in the

Upper Display Line

and on the top line of the semi-OSD display.

Next, press the

‹

›

Navigation Buttons

until the desired preset memory bank letter

appears in the

Lower Display Line

and in the

bottom line of the semi-OSD display. Next, press the

Memory Button

and note that a dash

will start to flash next to the preset memory bank

letter. Within five seconds, press the

Numeric

Button

from 1 to 8 for the memory slot

you wish to use.

• To tune up or down through a list of channels stored

in the currently active preset memory, press the

Preset Up/Down Buttons

. You may also

use the

Preset Station Selector

on the front

panel, or the

Prev/Next Transport Controls

on the ZR 10 remote. To change to another preset
bank, press the

Set Button

and then

press the

‹

›

Navigation Buttons

until the desired preset memory bank letter appears
in the

Lower Display Line

and in the bottom

line of the semi-OSD display.

• Each XM Radio channel is assigned a category,

which may be viewed by pressing the

Tuning

Mode Selector

. You may search for

an XM channel in any of the categories by first
pressing the

Set Button

and then

pressing the

‹

›

Navigation Buttons

until the desired category name appears in the

Lower Display Line

and in the bottom line

of the semi-OSD display. Press the

Set Button

again to start the search for the next

channel in that category.

• Note that you may see a

message,

indicating that the XM tuner is downloading content
and may not be able to operate. If the message
continues to appear, check to see whether the XM
antenna is properly positioned toward a south-facing
window, experiment with the antenna position, or
change to another input and then reselect XM Radio.

Recording

In normal operation, the audio or video source
selected for listening through the AVR 645 is sent to
the record outputs. This means that any program you
are watching or listening to may be recorded simply
by placing machines connected to the outputs for

Tape Outputs

Video 1 Audio

and

Video

Outputs

in the record mode.

When a digital audio recorder is connected to the

Digital Audio Outputs

, you are able to

record the digital signal using a CD-R, MiniDisc or
other digital recording system.

NOTES:

• The digital outputs are active only when a digital sig-

nal is present, and they do not convert an analog
input to a digital signal, or change the format of the
digital signal. In addition, the digital recorder must
be compatible with the output signal. For example,
the PCM digital input from a CD player may be
recorded on a CD-R or MiniDisc, but Dolby Digital
or DTS signals may not.

• The

Front-Panel Video 4

and

Coaxial 4

jacks may be configured for use as outputs, allowing
connection to a recorder, when the steps shown in
the section below are followed.

• Please make certain that you are aware of any

copyright restrictions on any material you copy.
Unauthorized duplication of copyrighted materials
is prohibited by federal law.

Front-Panel Connections

In addition to the rear-panel digital and analog outputs,
the AVR 645 offers Harman Kardon’s exclusive config-
urable front-panel output-jack feature. For easy con-
nection of portable devices, you may switch the front-
panel

Video 4 Jacks

or the

Coaxial Digital 4

Jack

from an input to an output by following

these steps:

1. Press the

OSD Button

∫

to view the

MASTER MENU

(Figure 1).

2. Press the

Set Button

to enter the

IN/OUT SETUP

menu (Figure 2).

3. Press the

Navigation Button

that the on-screen cursor is next to

VIDEO 4

COAXIAL 4

4. Press the

Set Button

and then press

the

‹

›

Navigation Buttons

so that

the word

OUT

is highlighted.

5. Press the

Set Button

to enter the

change.

6. Press the

OSD Button

∫

to exit the menus

and return to normal operation.

Once the setting is made, the

Input/Output Status

Indicator

will turn red, indicating that the jacks are

now outputs, instead of in the default setting as inputs.
Once changed to an output, the setting will remain as
long as the AVR 645 is turned on, unless the setting
is changed in the OSD menu system, as described
above. However, once the AVR 645 is turned off, the
setting is canceled. When the unit is turned on again,
the front-panel jacks will return to their normal default
setting as inputs. If you wish to use the jacks as outputs
at a future time, the setting must be changed again
using the OSD menu system, as described above.

Output Level Trim Adjustment

Normal output level adjustment for the AVR 645 is
established using EzSet/EQ, as outlined on pages
27–30. In some cases, however, it may be desirable
to trim the output levels using program material such
as a test disc, or a selection you are familiar with.
Additionally, the output level for the subwoofer can
only be adjusted using this procedure.
