OPERATION  13

Preset Tuning
Up to 30 stations may be stored in the HK 3370’s
memory for easy recall using the front panel con-
trols 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 and PRESET indicators will
light and flash in the Main Information 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 automatically
enter each station that may be tuned with
acceptable quality into the HK 3370’s preset
memories, first select the FM band. Next, press
and hold the Auto Preset button ¬ until the
MEMO and PRESET indicators begin to flash,
hold on until the station frequency indication
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 accept-
able signal strength. The HK 3370 will automati-
cally 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 up to two more cycles until the
remaining vacant preset memory spaces have
been filled.
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 completely fill
the preset memories, and overwrite any previous-
ly memorized presets for either AM or FM sta-
tions.

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 the same
frequency (if more than one scan is made) or on
more than one frequency. These unwanted sta-
tions 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 pre-
set stations one by one

,

press the Preset but-

tons % ∂ 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 3370’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 and PRESET 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.

RDS (Radio Data System) transmits station call
signs or network information, station program
type, text messages about the station or specifics
of a musical selection and the correct time.

RDS Tuning
When an FM station is tuned in and it contains
RDS data, the HK 3370 RDS will automatically
display the station’s call sign, with some private
stations also other informations changing all 2 to
5 seconds, and the RDS indicator will light in the
Information Display as well as indicators for the
RDS services program type PTY (see below) and
traffic announcement TA (see page 14) if trans-
mitted by the station. As soon as a radiotext mes-
sage is received completely the radiotext indica-
tor RT will turn on too.

RDS Display Options
When an RDS station is tuned, press RDS Dis-
play button 

on the remote or FM & on the

front panel to cycle through the RDS displays in
the following order:

• The Station name (or other Program informa-
tion with some private stations).

• The station’s frequency.

• The Program Type (PTY) as shown in the follow-
ing list in this manual.

• A “text” message (RT) containing special infor-
mation from the broadcast station. Note that this
message will scroll across the display to permit
messages longer than the eight positions in the
display. Depending on signal quality it may take
up to 30 seconds for the text message to appear,
in the meantime the word TEXT will flash in
the display when RT is selected.

• The current time of day (CT) as transmitted by
the station. It may take up to two minutes for the
time to appear, in the meantime the word
TIME

will flash in the display when CT is

selected. Note that the accuracy of the time mes-
sage is set by the radio station, not the 
HK 3370 RDS.

• Some RDS stations may not choose to include
some of these additional features. If the data
required for the selected mode is not being trans-
mitted, the Information Display will show a
N O PTY

, N O TEXT or N O TIME mes-

sage after the individual time out.

• In any FM mode the RDS function requires a
strong enough signal for proper operation. If you
receive a partial message or see any RDS indica-
tor going on and off, try slowly adjusting the
antenna to improve the signal strength or tune to
another, stronger, RDS station.

Program Search (PTY)
A major benefit of RDS is its ability to encode
broadcasts with Program Type (PTY) codes that
indicate the type of material being broadcast. The
following list shows the abbreviations used to
indicate each PTY along with an explanation of
the PTY:

• RDS O NLY: (see item 3 below)

• TRAFFIC: Traffic Information 

and Road Conditions (see Note below)

• POP M: Popular Music

• ROCK M: Rock Music

• M.O.R M: Middle-of-the-

Road Music

• LIGHT M: Classical Music

• CLASSICS: Serious Classical Music

• OTHER M: Other Music

You may search for a specific Program Type (PTY)
by following these steps:

1. Press the RDS PTY button 

and note that

the Information Display will show SELECT
PTY

.

2. After three seconds, the display will show the
PTY that was selected for the last PTY search. If
you wish to use the same PTY, press the RDS
PTY button 

again within six seconds, and

the tuner will begin to search for the first station
with the appropriate PTY and acceptable signal
strength.

3. To search for a different PTY, press the Tuning
Up/Down buttons î† ) while the last PTY
selected is still displayed to scroll through the list
of available PTY types. To search for the next
available station with any RDS data, select RDS
ONLY

as the PTY type.

4. When the PTY is selected, press the RDS PTY
button 

within six seconds, and note the PTY

indicator will flash in the Information Display. The
HK 3370 RDS will go into an automatic search
mode and attempt to find the next station with

acceptable signal strength that matches the
desired PTY type. Press the RDS PTY button 
twice again to find another matching station.
When a station is tuned, the search will stop, a
message RDS will blink in the Information
Display and then the Display will show the sta-
tion’s “Call Letters” or other “Program Service”
information.

5. While the PTY Indicator flashes in the display
the tuner will make one complete scan of the
entire FM band for the text station that matches
the desired PTY type and has acceptable recep-
tion quality. If no such station is found, the word
NONE

will appear briefly in the Information

Display, and the tuner will return to the last FM
station in use before the search.
To turn off the PTY Search at any time, press the
RDS PTY button again.

NOTE: Many stations do not transmit a specific
PTY. The display will show NONE, when such a
station is selected and PTY is active.

NOTE: Some stations transmit constant traffic
information. To identify as traffic station, they
transmit a specific traffic code constantly, which
causes the TA Indicator to light in the display.
These stations can be found by selecting
TRAFFIC

, the second option in the PTY list.

The HK 3370 will find the appropriate station,
even if it is not broadcasting traffic information
when the search is made.

In normal operation, the audio source selected
for listening through the HK 3370 is sent to the
Tape Mon Rec Out

 and Tape 2 Rec Out

 outputs. This means that any program you are
listening to may be recorded simply by placing
machines connected to the outputs for Tape
Monitor

 or Tape 2  in the record mode.

Moreover the source connected to Tape 2 Play
 may be recorded to a recorder connected to
Tape Mon

, rather than turned around.

When a tape recorder with separate record and
playback heads is used, you may monitor the out-
put of the recording by selecting the Tape
Monitor Input Selector 9 ç. Note that the
T-Mon Indicator will light in the Main
Information Display Û to remind you that
you are listening to the record playback instead
of the actual input source being recorded.

As long as Tape Monitor 9 ç is selected the
previously selected input source remains routed
to the Record Outputs

 . Press the Tape

Monitor Input Selector 9 ç again to turn
the monitoring off and listen to the actual input
source. Note that changing the Bass, Treble or
Balance control will not affect the recordings,
only the preamp and speaker outputs.

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 3370 will retain information such as
programmed presets for a virtually infinite time
without being connected to a main power source.

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 3370 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.

OPERATION

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) repre-
sents 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 3370.
Source Selectors ç need not to be pressed
with each function, but only when you intend to
skip to another device to be controled.

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. Please refer to the table below for specif-
ic information on the default functions of the
affected keys for these devices.
