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 theFM 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.

7. DOWN / UP 1 and 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, “2TUNED 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.

8. VFL DISPLAY

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
