Optimus STAV-3780 owner manual Using MPX Mode, Adjusting Balance, Memory Tuning

Basic Operation

Memory Tuning

Notes:

•If you store a frequency in a memory that already contains a frequency, you replace the previous frequency.

•If your receiver is disconnected from AC power for several days, it loses all the stored frequencies.

Memory tuning lets you store up to 30 AM or FM frequencies in three different classes (10 frequencies in each class), then quickly tune to a class and station.

Follow these steps to store a station in a memory location using the front panel controls. (You cannot store a station in a memory using the remote control.)

1.Press FM/AM to select the tuner, then press FM/AM again to select the desired band.

2.Tune to the frequency you want to store.

If desired, press MPX MODE (MPX on the remote control) for FM stereo or monaural sound (see “Using MPX Mode”). This setting is also stored in memory.

3.Press MEMORY. The class (A, B, or C) and _ _ (for the channel num- ber) flash on the display for about 5 seconds.

4.Press CLASS until the class you want (A, B, or C) appears, then press STATION until the channel number you want appears.

In about 5 seconds, the class and channel number light steadily, indicating the receiver stored the frequency.

To tune to a stored station, press CLASS so the desired class number appears, then repeatedly press STATION to select the channel. Or, you can directly enter the channel number using that number’s key on the remote control.

Using MPX Mode

To receive FM stations in stereo, press MPX MODE so MONO disappears from the display. STEREO appears when you receive an FM broadcast in stereo.

You can improve the reception of weak FM stations by pressing MPX MODE until MONO appears. This reduces noise while you listen to a weak FM station, but you get monaural instead of stereo sound.

Adjusting Balance

The TONE/BALANCE control lets you adjust the sound balance between the left and right speakers. If you properly position the speakers and your listening area is centered between them, the center control setting is usually best (see “Positioning Speakers” on Page 5).

For an unusual speaker placement, adjust the speaker balance as follows:

1.Press FM/AM to select the tuner, then press FM/AM again to select the FM band.

2.Press MPX MODE so MONO appears. The sound is monaural instead of stereo, so each speaker delivers the same output.

3.Repeatedly press SELECT on the front of the receiver until BALANCE appears. Then press L BALANCE R until you hear the sound coming equally from each speaker when you are in the listening area.

4.Press MPX MODE so MONO disappears from the display.
