The AVR 144 remote is capable of controlling seven devices, including
the AVR itself. During the installation process, you may program the
codes for each of your source components into the remote. Each time
you wish to use the codes for any component, you will need to first
press the Selector Button for that component. This changes the button
functions to the appropriate codes for that product.

Each Input Selector has been preprogrammed to control certain types
of components, with only the codes specific to each brand and model
changing, depending on which product code is programmed. The
device types programmed into each selector may not be changed.

DVD:

Controls DVD players and recorders.

CD:

Controls CD players and recorders.

Tape:

Controls cassette decks.

Video 1:

Controls VCRs, TiVo

®

and DVRs.

Video 2:

Controls cable and satellite television set-top boxes.

Video 3:

Controls televisions and other video displays.

For example, if you have inserted a disc in your CD player and you
would like to skip ahead three tracks, but you then find that the volume
is too loud, you would follow this procedure:

1.

Press the CD Input Selector to switch to the codes that control your

CD player.

2.

Press the Play Button (in the Transport Controls section) if the disc is

not already playing.

3.

Press the Skip Up Button three times to advance three tracks.

4.

Press the AVR Button so that you can access the Volume Controls.

5.

Press the Volume Down Button until the volume level is satisfactory.

Any given button may have different functions, depending on which
component is being controlled. Some buttons are labeled with these
functions. For example, the Sleep and DSP Surround Buttons are
labeled for use as Channel Up/Down Buttons when controlling a televi-
sion or cable box. See Table A8 in the appendix for listings of the

that operate the receiver.

Input Selectors:

Press one of these buttons to select a source

device, which is a component where a playback signal originates, e.g.,
DVD, CD, cable TV, satellite or HDTV tuner. This will also turn on the
receiver and switch the remote to the codes that operate the source
device.

AM/FM Button:

Press this button to select the tuner as the source,

or to switch between the AM and FM bands.

6-Channel Input Selector:

Press this button to select the 6-

Channel Inputs as the audio source. The receiver will use the video input
and remote control codes for the last-selected video source.

Dim:

Press this button to partially or fully dim the front-panel display.

Test Tone:

Press this button to activate the test tone for output-level

calibration.

TV/Video:

This button has no effect on the receiver, but is used to

switch video inputs on some video source components.

Sleep Button:

Press this button to activate the sleep timer, which

shuts off the receiver after a programmed period of time of up to
90 minutes.

Volume Controls:

Press these buttons to raise or lower the volume,

which will be shown in decibels (dB) in the Message Display.

DSP Surround:

Press this button to select a DSP surround mode

(Hall 1, Hall 2, Theater).

On-Screen Display (OSD):

Press this button to activate the on-

screen menu system.

Channel Level:

Press this button to set the output levels for each

channel so that all speakers sound equally loud at the listening position.
Usually this is done while playing an audio selection, such as a favorite CD,
as described in the Initial Setup section.

Speaker Setup:

Press this button to configure speaker sizes, that is,

the low-frequency capability of each speaker. Usually this is done using
the on-screen menu system, as described in the Initial Setup section.

Each precaution in this manual should be followed during servicing.
in the parts list are special significance to safety. When replacing a component identified with
, use only the replacement parts designated, or parts with the same ratings or resistance, wattage, or voltage that are designated in the
parts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts are acceptably
insulated from the supply circuit before retuming the product to the customer.
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called
Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field effect transistors and
The following techniques should be used to help reduce the incidence of component damage caused by static electricity.
1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on
your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device,
which should be removed for potential shock reasons prior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to
prevent electrostatic charge build-up or exposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.
4. Use only an anti-static solder removal device. Some solder removal devices not classified as 'anti-static' can generate electrical charges
5. Do not use freon-propelled chemicals. These can generate electrical change sufficient to damage ES devices.
6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement
ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material.)
7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the
chassis or circuit assembly into which the device will be installed.
Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together
or your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices.

Processor Reset
In the rare case where the unit’s operation or the
displays seem abnormal, the cause may involve
the erratic operation of the system’s memory or
microprocessor.
To correct this problem, first unplug the unit from
the AC wall outlet and wait at least three
minutes. After the pause, reconnect the AC
power cord and check the unit’s operation. If the
system still malfunctions, a system reset may
clear the problem.
To clear the AVR’s entire system memory
including tuner presets, output level settings,
delay times and speaker configuration data, first
put the unit in Standby by pressing the System
Power Control
button 2. Next press and hold
the OK button 6 for five seconds.
The unit will turn on automatically and show the
word RESET in the Display for a few seconds.
Then it reverts to normal ON status. Note that
once you have cleared the memory in this manner,
it is necessary to re- establish all system
configuration settings and tuner presets.
NOTE: Resetting the processor will erase any
configuration settings you have made for
speakers, output levels, surround modes, digital
input assignments as well as the tuner presets.
After a reset the unit will be returned to the
factory presets, and all settings for these items
must be reentered.
If the system is still operating incorrectly, there
may have been an electronic discharge or severe
AC line interference that has corrupted the
memory or microprocessor.
If these steps do not solve the problem, consult
an authorized Harman Kardon service depot.
