OPERATION  17

Using the Remote Control
It is convenient to think of the functions of the
remote control buttons in terms of “pages”,
where each source device (e.g., CD player) rep-
resents its own page of remote functions. The
result is that some of the keys will perform dif-
ferent functions depending upon which device
page has been selected prior to pressing the
key. Device pages are selected by pressing the

Source Selectors ç, which also changes the
input source selection on the HK 3470.

Three of the device pages are factory-
programmed to operate compatible
Harman Kardon products. The Tape Monitor
device page is programmed as a factory default
to operate Harman Kardon cassette decks. The
Tape 2 page defaults to Harman Kardon CD-R

control codes. The CD page defaults to
Harman Kardon CD player or changer control
codes. Note that all of these keys may be pro-
grammed in the learning mode to transmit dif-
ferent remote codes to perform other functions
and/or operate other devices. Please refer to
the table below for specific information on the
default functions of the affected keys for these
devices.

18 OPERATION

Programming the Remote Control
Although the remote control is prepro-
grammed at the factory to operate compatible
Harman Kardon CD recorders, players and
changers, and cassette decks, you may program
the remote with control codes that operate other
devices.

Not all of the buttons on the HK 3470 remote
control may be programmed. If you attempt to
“learn” a code into a button not shown in the
table below, you may experience undesired
responses to remote commands, or lose the abil-
ity to perform some functions using the remote
control.

You may program remote buttons only on these
pages: AUX, TAPE 2, TAPE MON, and CD. Codes
may not be programmed to the pages for Phono,
AM or FM.

Only the buttons shown in this table with an
“X” may be programmed.

OPERATION  19

Programming the Remote Buttons 
Is a Simple Procedure
Step 1: Place the HK 3470 remote control and

the remote control for the other device (e.g.,
compact disc player) so that their infrared
transmitter windows face each other at a dis-
tance of about 0.5 to 1 cm.

Step 2: Simultaneously press the Learn button

√

and the Source Selector ç that corre-

sponds to the device whose codes you are try-
ing to program (e.g., press the CD button
along with the Learn button). The LED
Indicator Ω will blink twice and remain lit.

Step 3: Press and release the button on the HK

3470 remote that you wish to program. Make
sure that it is one of the programmable but-
tons listed in the table on page 18. The LED
Indicator Ω will blink once and remain lit.

Step 4: Press and hold the button on the other

device’s remote whose code you wish to 
program into the HK 3470 remote until the
LED Indicator Ω blinks three times and
remains lit, then release the button on the
other remote.

If the LED Indicator Ω flickers for five sec-
onds instead of blinking three times and
remaining lit, the learning operation was
unsuccessful. Try the procedure again, starting
from Step 2, making sure that the transmitter
windows of the two remotes face each other,
and that the button you are trying to program
on the HK 3470 remote is listed in the table
on page 18.
Also varying the distance between both
remotes may help.

Step 5: To program additional buttons, repeat

Steps 2 through 4.

Step 6: To exit the learning mode, either press

the Learn button √ once, or wait 20 seconds
for the remote to automatically return to nor-
mal operation.

Resetting One Key to Default Setting
When a new code is programmed into the
remote, it overwrites the previous code for that
button on that page. However, should you make
a mistake, it is possible to reset any button to its
factory default using the following procedure:

Step 1: Enter the learning mode by simultane-

ously pressing any of the Device buttons ç
and the Learn button √.

Step 2: Press and release the particular device

button for the page containing the key you
wish to reset. The LED Indicator Ω will
blink once and remain on.

Step 3: Use the Numeric Keys ˚ to enter the

numbers “777”. The LED Indicator Ω will
blink for each entry.

Step 4: Press and release the button that you

wish to reset. The LED Indicator Ω will
blink three times to indicate that the button
has been reset to the factory default code.

Step 5: You may repeat Step 4 to reset the

codes for other keys. If you wish to reset the
codes for an entire device page, see below.

Step 6: To exit the learning mode, either press

the Learn button √ once, or wait 20 seconds
for the remote to automatically return to nor-
mal operation.

Resetting an Entire Device Page
If you wish to reset all of the codes for a particu-
lar device, you need not individually reset every
button on that page of the remote. This is the
procedure for resetting the codes on a particular
page.

Step 1: Enter the learning mode by simultane-

ously pressing any of the Device buttons ç
and the Learn button √.

Step 2: Press and release the particular device

button for the page you wish to reset. The
LED Indicator Ω will blink once and remain
on.

Step 3: Use the Numeric Keys ˚ to enter the

numbers “888”. The LED Indicator Ω will
blink for each entry.

Step 4: The LED Indicator Ω will remain on

for one second, and then blink three times to
indicate that it has reset the group of keys for
the selected device page. That device page will
now operate the factory default set of codes.

Resetting the Entire Remote
It is also possible to completely reset all of the
programmed codes in the remote to the factory
default settings. Use the following procedure:

Step 1: Enter the learning mode by simultane-

ously pressing any of the  Device buttons ç
and the Learn button √.

Step 2: Press and release any device button

other than PHONO, AM or FM. The LED
Indicator Ω will blink once and remain on.

Step 3: Use the Numeric Keys ˚ to enter the

numbers “999”. The LED Indicator Ω will
blink for each entry.

Step 4: The LED Indicator Ω will remain on

for five seconds, and then blink three times to
indicate that it has reset all of the keys on the
remote. The entire remote will now operate
the factory default set of codes.

This product is equipped with a memory backup
system that preserves tuner presets if the unit is
accidentally unplugged, turned off completely
with the Main Power switch 1 or subjected
to a power outage. The unit’s memory is stored in
an EEPROM, and thus the HK 3470 will retain
information such as programmed presets without
being connected to a main power source virtually
indefinitely.

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 min-
utes. 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 reset the system, first turn the HK 3470 off by
pressing the Main Power Switch 1 and then
releasing it so that it extends out beyond the
front panel and the word “OFF” is visible in red
at the top of the switch.

Next, press and hold the T-Mon and CD Input
Selector buttons 9# on the front panel
ONLY. While holding these buttons in, press the
Main Power Switch 1 in until it latches, so
that the button is flush with the front panel.

The Main Information Display will briefly show
the word R E S ET, you can release the buttons
pressed now, the unit will return to Standby
mode.

Note that when the system is reset in this fash-
ion, all tuner presets will be lost and 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 mem-
ory or microprocessor.

If these steps do not solve the problem, consult
your dealer or an authorized Harman Kardon
service center.
