Memory Backup; Processor Reset - Harman Kardon HK3470 Owner's Manual

Operation
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
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 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 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 blinks three times and
remains lit, then release the button on the
other remote.
If the LED Indicator 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
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
blink once and remain on.
Step 3: Use the Numeric Keys
numbers "777". The LED Indicator
blink for each entry.
Step 4: Press and release the button that you
wish to reset. The LED Indicator
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
that corre-
the Learn button
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
and the Learn button
Step 2: Press and release the particular device
button for the page you wish to reset. The
LED Indicator
on.
Step 3: Use the Numeric Keys
numbers "888". The LED Indicator
blink for each entry.
Step 4: The LED Indicator
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
and the Learn button
Step 2: Press and release any device button
other than PHONO, AM or FM. The LED
Indicator will blink once and remain on.
Step 3: Use the Numeric Keys
numbers "999". The LED Indicator
blink for each entry.
Step 4: The LED Indicator
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
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.
