OPERATION

Warning: To prevent possible hearing loss, turn VOLUME to MIN before you turn on the receiver or change the program source. After you turn on the receiver or change the program source, adjust VOLUME to a comfortable listening level.

You can use the supplied remote control by pointing it at the receiver’s front panel and pressing the desired button(s). Many buttons on the remote control work the same as buttons on the receiver’s front panel. Use these buttons exactly as you would use the corresponding buttons on the receiver.

Follow these steps to use the receiver.

1.Press POWER to turn on the receiver. It takes about 5 seconds to hear sound.

2.Select the speakers. An indicator lights next to the A and/ or B to show which speakers are on.

If you connected speakers only to the A (or B) SPEAKERS terminals, press SPEAKERS A (or B) to turn on only those speakers. Do not press both SPEAKERS A and B because doing so turns off all speakers even though both indicators are on.

If you connected speakers to both the A and B SPEAKERS terminals, you can:

Press SPEAKERS A or B to turn on either pair of speak- ers for a two-speaker effect.

Press SPEAKERS A and B to turn on both pairs of speakers for a four-speaker effect.

Press SPEAKERS A and/or B to turn off all speakers so you can listen privately with headphones (see “Using Headphones” on Page 11).

3.Select a program source.

To tune to a radio station, see “Direct Tuning (Remote Control Only)” on Page 10.

To listen to signals from the component connected to the

TAPE MONITOR jacks, press TAPE MONITOR so TAPE MON appears.

To listen to a source other than the one connected to the

TAPE MONITOR jacks, press TAPE MONITOR so TAPE MON disappears. Then press CD, PHONO, or AUX (CD, PHONO, or AUX appears).

4.Turn VOLUME clockwise to increase the volume or counterclockwise to decrease it. Or, you can use VOLUME and on the remote control.

5.To adjust the tone, turn BASS and TREBLE toward + or

. To increase the high and low ranges of sound at low volume, press LOUDNESS. (To turn off this feature, press

LOUDNESS again.)

6.To adjust the balance of sound between the left and right speakers, see “Adjusting Balance” on Page 11.

7.When you finish using the receiver, press POWER to turn it off.

USING THE SLEEP TIMER

The sleep timer lets you set the receiver to play for up to 90 minutes, then automatically turns off.

1.To set the timer, turn on the receiver then press SLEEP on the remote control. The display dims and shows SLEEP 90 SLEEP.

2.To set the sleep timer for less than 90 minutes, repeatedly press SLEEP to decrease the time by 10 minutes for each press of the button. Once you select the time, the receiver displays the program source. (SLEEP stays on the display in small letters until automatic shut-off.)

3.To briefly see the time remaining, press SLEEP once.

TUNING THE RADIO

Your receiver has four types of electronic tuning — manual, automatic, direct, and memory.

Note: For weak signals, we recommend manual tuning.

Manual and Automatic Tuning

Follow these steps to manually or automatically tune to the stations.

1.Press FM or AM on the front panel (or on the remote control) to select the desired band. The receiver tunes to and displays the frequency last selected in that band.

2.If CH appears on the right side of the display, press MODE to change the receiver to manual-tuning mode. MANUAL briefly appears.

3.To manually select the next higher or lower frequency, press TUNING UP or DOWN once. Or, hold down the button to rapidly scan through the frequencies; release the button to stop scanning.

To automatically search for the next higher or lower station, briefly hold down TUNING UP or DOWN to begin rapidly scanning through the frequencies. The receiver searches up or down the band, stopping on the next strong station.

Notes:

TUNED appears when the received signal is strong.

STEREO appears when the received FM broadcasts are in stereo.
