The DISPLAY button toggles the display to show
either the station frequency or user entered station
name. If no user name was entered the display will
just flash once.
4. FM MUTE / MONO
This button combines two functions; it switches the
tuner from Stereo to Mono and disengages the mut-
ing circuitry at the same time. The muting circuit will
mute the tuner in between radio stations when
searching or tuning. This way the tuning noise is
avoided.
Very weak radio station signals however may be
suppressed by the muting circuit. if such a very weak
station is in stereo it will have a high level of back-
ground hiss. Switching to Mono Mode and disengag-
ing the muting circuit by depressing the FM
MUTE/MONO button will allow the station to be heard
and will cancel most or all of this background noise.
In normal operation the mute circuit is engaged, the
display indicates “FM MUTE”. Press the FM
MUTE/MONO button to disengage the muting circuit
and switch from stereo to mono reception. “FM
MUTE” will extinguish in the display. Also, “STEREO”
will extinguish if a stereo broadcast was received.
Press the FM MUTE/MONO switch again to return to
Auto Stereo FM operation.
In combination with the MEMORY button (No. 5) a
preset number can be emptied. (Refer to the sepa-
rate chapter “Storing and Recalling Presets” for more
information.)
5. MEMORY
The MEMORY button is used to store stations into
the Preset Memory (1-30 Presets on FM, 1-10
Presets on AM), used in conjunction with the
DOWN/UP (No. 7) buttons on the front panel. In com-
bination with the FM MUTE/MONO button (No. 4) a
preset number can be emptied. When Memory is
active, the Preset number flashes and the red “MEM-
ORY” indicator is shown in the Display Panel. If no
other button is pressed within 10 seconds “MEMO-
RY” will stop flashing and the receiver will default to
its previous state.
Refer to the separate chapter “Storing and recalling
Presets” for more information.
6. PRESET / TUNE
The PRESET/TUNE button toggles between the
Preset and Tune mode. When Preset mode is select-
ed, “PRESET” lights up in the display area.
Up to 40 Presets, either AM (10 Presets) or FM (30
Presets), can be stored.
Refer also to separate chapter “Storing and
Recalling Presets” for more information.
7. DOWN / UP
1
1
and
2
2
The function of these buttons depends on the tun-
ing mode selected with the PRESET/TUNE button
(No. 6). The PRESET/TUNE button toggles between
the two operation modes:
a) Preset mode (indicated in the display area): Press
the “
1
” (down) button to scroll to a lower number
Preset; press the “
2
” (up) button to scroll to a
higher Preset number. This is a “wrap-around”
function, so that going from the highest number
Preset, the tuner will go to the lowest Preset num-
ber or vice-versa when tuning either up or down.
b) Tune mode: Press the “
1
” (down) or “
2
” (up)
button for more than 1/2 second to engage auto-
matic tuning respectively up or down the frequency
band. The tuner will search automatically for the
first reasonably strong radio station, where it will
stop. Press the Down/Up button again for 1/2 sec-
ond to start searching again.
NOTE:
Automatic tuning is available on both FM and AM.
By briefly tapping the “
1
” (down) or “
2
” (up) but-
tons you can engage manual tuning respectively
down or up the frequency band for precise tuning to a
specific frequency. With each successive tap of the
keys, the tuner will take 0.1 MHz steps (120V ver-
sion) or 0.05 MHz steps (230V version) on FM so you
can accurately tune into the desired frequency. For
AM the tuning steps are factory set at 9 kHz for the
230V version or 10 kHz for the 120V version). Set the
AM STEP switch on the back panel (No. 2 in back
panel drawing) to manually set the AM tuning steps to
9 or 10 kHz (refer also to chapter “Rear Panel
Connections” section 2: “AM stepping frequency”).
This tuning mode can also be useful when trying to
receive a radio station which is too weak for the auto
search mode. When tuned accurately to a station,
“
2
TUNED
1
” will light up in the display. Very weak
radio station signals however may be suppressed by
the muting circuit. If such a very weak station is in
stereo it will have a high level of background hiss.
Switching to Mono Mode and disengaging the muting
circuit by depressing the FM MUTE/MONO button
(No. 4) will allow the station to be heard and will can-
cel most or all of this background noise.
Refer to the separate chapter “Storing and
Recalling Presets” for more information.

Vacuum Fluorescent Display. The display area will
show all vital information when the unit is operational.
9. VOLUME
The Volume control adjusts the overall loudness of
the signals being fed to the loudspeakers. Unlike con-
ventional controls, the T 751’s volume control doesn’t
