Basic Operation

Using FM Mono

To receive FM stations in stereo, press FM MONO until MONO disappears from

 

the display. STEREO appears on the display 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.

Balance Control

The 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 “Position- ing Speakers” on Page 5).

For an unusual speaker placement, adjust BALANCE as follows:

1.Select TUNER. Then press FM/AM to select the FM band.

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

3.Turn BALANCE until you hear the sound coming equally from each speaker when you are in the listening area.

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

Muting the Receiver

To temporarily mute the sound, press MUTING on the remote control. MUTING appears. Press MUTING again to restore the audio level.

Using Headphones

To listen with headphones (not supplied), insert the headphones’ 1/4-inch plug into the receiver’s front panel PHONES jack. To silence the speakers, set A and B SPEAKERS to the out position.

Listening Safely

To protect your hearing, note the following when using headphones.

•Set the volume to its lowest setting before you begin listening. After you begin listening, adjust volume to a comfortable level.

•Do not listen at extremely high volume levels. Extended high- volume listening can lead to permanent hearing loss.

•Once you set the volume, do not increase it. Over time, your ears adapt to the volume level, so a volume level that does not cause discomfort might still damage your hearing.

Cassette Deck Features

You can connect two cassette decks to the receiver. Selecting either TAPE 1/ VCR or TAPE 2 MONITOR lets you hear the playback from the cassette deck you connected to the receiver’s corresponding (TAPE 1/VCR, TAPE 2 MONITOR) jacks.
