<< FREQUENCY >
Manual Tuning
Automatic Tuning
FM MOOEAAJTE
To receive an AM/FM broadcast, select either AM or FM using the AM button or FM button.
Then tune to the precise frequency using the FREQUENCY buttons.
Tuning
Tune to the frequency of a desired station using the FREQUENCY buttons. Pressing the right
button increases the frequency, and pressing the left button decreases the frequency. Tapping
the FREQUENCY button once changes the frequency in steps of 10 kHz for AM and 0.1 MHz
for FM.
There are two tuning modes: Manual and Automatic.
If you know the frequency of a desired station, hold down the FREQUENCY button to start the
frequency changing quickly. Release the FREQUENCY button near the desired station and tap
it repeatedly until you arrive at the correct frequency.
If you want to scan frequencies for a desired station, hold down the FREQUENCY button to
start the frequency changing quickly. When you release the FREQUENCY button, the
frequency continues to change until it reaches a station.
When a station is correctly tuned, the “TUNED” light appears on the display window.
Once a tuned frequency is preset, it can be directly recalled using the TUNER buttons. For
details, see pages 16-17.
NOTE: When you use automatic tuning, weak stations are ignored. To pick up weak
Stations, use manual tuning.
IMPORTANT! If the receiver is tuned fo a station but the “TUNED” light does not
appear, Iry rotating the antenna for better reception.
Selecting an FM Reception Mode
Pressing the FM MODE/MUTE switch switches between these modes.
The “MUTE-AUTO” light appears in the display window. You hear either stereo sound or
monaural sound, depending on the broadcast. If it is a stereo broadcast, the “STEREO” light
appears. This mode is also useful for suppressing static “noise” between stations.
The “MUTE-AUTO” light disappears. You hear monaural sound even if a broadcast is in
stereo. This mode is also useful when a stereo broadcast is noisy because of a weak signal.
NOTE: Using the Automatic Tuning mode, the sound of a broadcast with a weak signal
may be muted. In this case, select the monaural mode.

When you select PRO LOGIC or 3CH LOGIC program, you must also select a center channel
mode. The following modes are available:
“PHANTOM” _ Use this mode when no center speaker is used. The entire center channel
is reproduced through the front speakers. 3CH LOGIC doesn't have this
mode.
“NORMAL” _ Use this mode when the center speaker is smaller than the front speaker. The
bass frequencies in the center channel are reproduced through the front
speakers.
“WIDE” Use this mode when the center speaker is as large as the front speaker. The
entire center channel is reproduced through the center speaker.
“OFF” The center channel is muted.
To select one of these modes, use the CENTER MODE buton on the receiver. Each time you
