4. FM/AM

The FM/AM button switches the tuner section from the AM band to the
FM band and vice-versa. The Display Panel shows the frequency of the
tuned station and which band is selected. The FM tuning is in 0.05 MHz
increments, AM tuning is in 9 kHz or 10kHz increments, depending on
the version (9 kHz for the 230V version or 10 kHz for the 120V version).
To  change the AM increment tuning steps, press the FM/AM and CD
buttons at the same time. 

5. FM MUTE / MODE

This button combines two functions; it switches the tuner from FM
Stereo to Mono mode and disengages the muting 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 background hiss. Switching to Mono and disengaging the
muting circuit by depressing the FM MUTE/MODE 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/Mode button to disengage the muting
circuit and switch from stereo to mono reception. “FM MUTE” will
extinguish in the display. Also, “FM STEREO” will extinguish if a stereo
broadcast was received. Press the FM Mute/Mode switch again to return
to Auto Stereo FM operation.
In combination with the MEMORY button (No. 6) and DOWN/UP buttons
(No. 8) a preset number can be emptied. (Refer to the separate chapter
“Storing and Recalling Presets” for more information.)

6. 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. 8) buttons on the front panel. In combination with the FM
MUTE/MODE button (No. 5) and DOWN/UP buttons (No. 8) a preset
number can be emptied. When Memory is active, the Preset number
flashes and the red “MEMORY” indicator is shown in the Display Panel.
If no other button is pressed within 10 seconds “MEMORY” will stop
flashing and the receiver will default to its previous state.

Refer to the separate chapter “Storing and recalling Presets” for more
information.

7. PRESET / TUNE

The Preset/Tune button toggles between the Preset and Tune mode.
When Preset mode is selected, “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.

8. DOWN / UP 

AND 

The function of these buttons depends on the tuning mode selected with
the Preset/Tune button (No. 7). The Preset/Tune button toggles between
the two operation modes:

a)

Preset mode (indicated in the display area): Press the 

(down)

button to scroll to a lower number Preset; press the 

(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 number or vice-versa when tuning either up or
down.

b)

Tune mode: Press the 

(down) or 

(up) button for more

than 1/2 second to engage automatic 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 second to start searching again.

NOTE

Automatic tuning is available on both FM and AM.

By briefly tapping the 

(down) or 

(up) buttons 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 0.05 MHz steps on FM so you can accurately tune into the
desired 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, “

TUNED

” 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 and disengaging the
muting circuit by depressing the FM MUTE/MODE button (No. 5) will
allow the station to be heard and will cancel most or all of this
background noise.

Refer to the separate chapter “Storing and Recalling Presets” for more
information.

9. VFL DISPLAY

Vacuum Fluorescent Display. The display area will show all vital
information when the unit is operational.

10. VOLUME & SET UP

In the default function, this control acts as a  Volume control, adjusting
the overall loudness of the signals being fed to the loudspeakers and
headphones. Unlike conventional controls, the T741’s volume control
doesn’t have a start or end position. Volume can also be adjusted from
the remote control handset using the Master Volume Up or Down
buttons. The Volume control does not affect recordings made using the
Tape, Video 3 and Video 4 outputs but will affect the signal going to the
Pre-amp output (Audio Pre Out). The volume level is indicated in the
display panel when it is being adjusted. After three seconds the display
defaults to its previous status. Volume setting can range from

to +18dB.

On the remote control handset, press the Mute button to temporarily
switch off the sound to the speakers and headphones. Mute mode is
indicated by “MUTING” flashing in red in the display area. Press Mute
again to restore sound. Mute does not affect recordings made using the
Tape, Video 3 and Video 4 outputs but will affect the signal going to the
Pre-amp output (Audio Pre Out) and headphones.
