Tuning for a Desired
Broadcast
Your tuner has special features
designed to give you the best
possible sound quality under a
variety of conditions.
Auto/Manual Tuning
Begin using this tuner with "AUTO
TUNING" activated. "AUTO TUNING"
will light up on the display panel. In
this mode, pressing the « or vw Tuning
buttons causes the tuner to step up or
down the broadcast band, stopping at
the next strong signal it receives.
This feature also allows the tuner to
receive broadcasts in stereo.
If you wish to receive a weak
broadcast signal, which the tuner
skips over in AUTO TUNING, only
then should you turn this feature off.
In this MANUAL TUNING mode,
pressing the a or v Tuning buttons
Operating Instructions
causes the tuner to step up or down
the broadcast band regardless of
whether a signal is present.
NOTE: In MANUAL TUNING mode, all
broadcasts are received in mono.
Mono tuning is included in this mode
because broadcasts too weak to be
received in the AUTO TUNING mode
are also too weak to be received in
stereo. If you later tune to a stronger
broadcast, be sure to also return to
AUTO TUNING mode.
Frequency Direct Tuning
This tuning feature allows you to
directly enter the desired broadcast
frequency:
1. Press the "Band" button for FM or
AM.
2. Press the "Freq Direct" button. The
digit locations in the display will begin
to blink.
3. Press the 10 numbered butions to
enter the desired broadcast frequency.
4. Press the "Enter" button. The
display will stop blinking.
If you try to enter a frequency that is
not within the broadcast band, the
display will continue to blink. In this
case, press the "Freq Direct" button
twice and return to step 3.
Preset Memory
The TU930 allows you to store up to
30 broadcast frequencies in its
memory. These can later be recalled
by pressing the numbered buttons on
the front panel or on the keypad of a
compatible system remote control (that
is not included with the TU930).
To enter a broadcast frequency in
memory:
1. Tune to the desired broadcast.
2. Press the memory buiton.
"MEMORY" will blink for 5 seconds,
during which a Memory Preset number
can be entered.
3. Press the 10 numbered buttons to
enter a Preset number from 1 to 30,
then press "Enter".
To recall a Preset from memory, press
the numbered buttons. The second
digit must be entered while the first
digit is still blinking. When single digit
Presets are entered the display will
stop blinking within 3 seconds.
To change a preset station, simply
enter the new setting. The old setting
is automatically erased.
Remote Control
If you wish to control your TU930 with
an external infrared remote sensor,
simply connect the wire from the
remote sensor to the REMOTE IN jack
on the back panel. A control wire may
then be run from the REMOTE OUT
jack to the Remote Input of another
stereo component. Alternatively, if you
have a stereo component with a built-in
infrared remote sensor and a Remote
Output jack, it may be possible to
connect this jack to the REMOTE IN
jack of your tuner. Not all components
are compatible, but it will not hurt to
experiment.
Once your TU930 is connected to an
external infrared sensor, you will need
a compatible remote control
commander. One such commander is
the remote control unit from Harmon
Kardon’s TU9600 tuner, available
through Harman Kardon’s Parts
Department.
Harman Kardon also offers
MasterworksTM, a universal remote
control that can be used not only with
your tuner, but with other components
as well, including TVs, VCRs, Cassette
Decks and CD Players. Masterworks
may be available from your Harman
Kardon dealer.
