Basic Operation

Memory Tuning

Notes:

•A class is a group of up to 10 station frequencies.

•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 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 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 five seconds, the class and channel number light steadi- ly, 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 FM MONO until MONO appears. This reduces noise while you listen to a weak FM station, but you get monaural instead of stereo sound.

Using Headphones

To listen using optional headphones (not supplied), insert the head- phones’ 1/4-inch plug into the receiver’s front panel PHONES jack and H.P SP appears on the display. The speakers are automatically silenced.

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 the 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.
