OPERATION  

The HK 3470’s tuner is capable of tuning AM, FM

the Direct button ∆, and then pressing the
Numeric Keys ˚ that correspond to the sta-

matically be tuned.

NOTE: When the FM reception of a stereo
station is weak, audio quality will be increased
by switching to Mono mode by pressing the FM
Mode button * ß until the STEREO indicator

goes out.

Preset Tuning
Up to 30 stations may be stored in the
HK 3470’s memory for easy recall using the front
panel controls or the remote. In order to program
preset stations into memory, you must use the
remote control.

To enter a station into the memory, first tune the
station using the steps outlined above. Then:

1. Press the Memory button ø on the remote.
Note that the MEMO E and PRESET C
indicators will light and flash in the Main Infor-
mation Display.

2. Within five seconds, press the Numeric Keys
˚

corresponding to the location where you wish

to store this station’s frequency.

For all preset numbers above ”3” the station will
be stored directly. Note that for the presets 1, 2
or 3 either you press the corresponding number
and wait for 5 seconds or you press a ”0” befor
you press the 1,2 or 3, then the station will be
stored at once.

3. Repeat the process after tuning any 
additional stations to be preset.

Auto Preset
• Preset stations may also be programmed auto-
matically for the entire FM band. To automatical-
ly enter each station that may be tuned with
acceptable quality into the HK 3470’s preset
memories, first select the FM band. Next, press
and hold the Auto Preset button ¬ until the
MEMO E and PRESET C indicators begin to
flash, hold on until the station frequency indica-
tion begins to increase. Release the button and
note that the tuner will search the entire FM
band, and stop briefly at each station that has
acceptable signal strength. The HK 3470 will
automatically assign a preset number to each
station, and then search for the next station.
If the FM tuner finds fewer than 30 FM stations
with acceptable signal strength, the Auto Preset
tuning will scan two more cycles or until the
remaining vacant preset memory spaces have
been filled with those found in the first scan.
The automatic scan process will stop when all 30
preset memory locations have been filled or the
entire FM band has been scanned three times or
the Auto Preset button ¬ is pressed again.

NOTE: Using the automatic tuning mode in
areas with more than 30 FM stations will com-
pletely fill the preset memories, and overwrite
any previously memorized presets for either AM
or FM stations.

TIP: The automatic scan process may enter sta-
tions that you do not wish to retain in the memo-
ry, or it may enter the same station on more than
one frequency. These unwanted stations may be
removed from the memory using the Preset Clear
function outlined below.

Recalling Preset Stations
• To manually select a station previously entered
in the preset memory, press the Numeric Keys
˚

that correspond to the desired station’s mem-

ory location.

• To manually tune through the list of stored
preset stations one by one

,

press the Preset

buttons % ∂ on the front panel or remote.

• To automatically scan through the stations
entered in the preset memory, press the Preset
Scan button @ œ on the front panel or
remote. The tuner will cycle through the list of
preset stations, stopping for five seconds at each
one. Press the button again to stop the scan at
your desired station.

Clearing Preset Stations
Unwanted preset stations may be erased from
the unit’s memory to make it easier to tune only
those stations you want.

To remove a preset station from the HK 3470’s
tuner memory, first tune to the station using the
Preset buttons % ∂ on the front panel or
remote, or by entering the preset number directly,
using the Numeric Keys ˚.

When the preset station to be removed has been
tuned, first press the Memory button ø. The
MEMO E and PRESET C indicators in the Main
Information Display will flash, and the actual preset
number will disappear from the display. Next, press
the Clear button Ñ within five seconds.

The preset station will be removed from the
memory, and the action will be confirmed by the
brief appearance of the word CLEAR and the
preset number location in the Main Information
Display. That memory location will now be empty,
and you may program a different station to that
location, or leave it empty.

The HK 3470 RDS is equipped with RDS (Radio
Data System), which brings a wide range of infor-
mation to FM radio. Now in use in many coun-
tries, RDS is a system for transmitting station call
signs or network information, a description of
station program type, text messages about the
station or specifics of a musical selection and the
correct time.

As more FM stations become equipped with RDS
capabilities, the HK3470 RDS will serve as an
easy-to-use center for both information and
entertainment. This section will help you take
maximum advantage of the RDS system.

RDS Tuning
When an FM station is tuned in and it contains
RDS data, the HK 3470 RDS will automatically
display the station’s call sign and the RDS indi-
cator P will light in the Information Display as
well as indicators for the RDS services program
type PTY O (see below) and traffic announce-
ment TA L (see page 16) if transmitted by the
station. As soon as a radiotext message is
received completely the radiotext indicator RT M
will turn on too.

RDS Display Options
The RDS system is capable of transmitting a wide
variety of information in addition to the initial
station call sign that appears when a station is
first tuned. In normal RDS operation the display
will indicate the station name, broadcast network
or call letters, with some private stations also
other information, changing every 2 to 5 seconds.
Pressing the RDS Display button enables
you to cycle through the various data types in the
following sequence:
