Receiving FM/AM Broadcasts
Tuning in a Station Directly — Direct Tuning
To correct the entered frequency
Repeat steps 3 to 4.
If you enter a frequency not covered by the tuning
interval
The entered value is automatically rounded up or down to
the closest value covered by the tuning interval.
Tuning intervals for direct tuning are the followings:
FM: 50 kHz interval
AM: 10 kHz interval (for US.A. and Canadian models)
9 kHz interval (for Australian model)
(To switch the tuning interval between 9 kHz and 10 kHz,
see page 17.)
When the entered frequency does not exist in the
receivable frequency range
The entered digits (up to 5 digits for FM or up to 4 digits for
AM) blink in the frequency display area, and reception does
not take place.
If this occurs, press DIRECT again, and enter the correct
frequency. The frequency range of the receiver is 87.50 to
108.0 MHz for FM, and 530 to 1710 kHz with 10 kHz interval
(U.S.A. and Canadian models) or 531 to 1602 kHz with 9
kHz interval (Australian model) for AM.
When an FM stereo program is noisy
When the unit receives an FM stereo program, the STEREO
indicator lights in the display window. If the stereo program
is noisy, press FM MODE to change the mode over to
MONO. This eliminates the stereo effect, but the noise will
be greatly reduced.
To return to the stereo mode, press FM MODE again.
