FM MONO

Basic Operation

Memory Tuning

Note: A class is a group of up to 10 sta- tion frequencies.

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 FM MONO for FM stereo or monaural sound (see “Using FM MONO”). This setting is also stored in memory.

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

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

In about five seconds, the class and channel number light steadily, indi- cating the receiver stored the frequency.

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

Using FM MONO

To receive FM stations in stereo, press 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 FM MONO 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 “Posi- tioning 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 FM MONO so MONO appears. The sound is monaural instead of ste- reo, so each speaker delivers the same output.

3.Repeatedly press TONE/BALANCE on the front of the receiver until BAL- ANCE appears. Then press DOWN/LEFT or UP/RIGHT until you hear the sound coming equally from each speaker when you are in the listening area.

4.Press FM MONO so MONO disappears from the display.
