Basic Operation

Tuning the Radio

Note: For weak signals, we recommend manual tuning.

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

Manual and Automatic Tuning

Follow these steps to manually or automatically tune to stations.

Hint: If none of the tuning buttons on the remote control operate, press TUNER first.

1.Press FM/AM (BAND on the remote control) to select the tuner. Then press FM/AM (BAND) again to select the desired band. The receiver tunes to and displays the frequency last selected in that band.

If A, B, or C and a single digit number appear to the left of the station fre- quency, press SELECT (BAND on the remote control) so the band name (AM or FM) appears.

2.To manually select the next lower or higher frequency, press TUNING ( FREQ on the remote control) once to manually select the next lower or higher frequency. Or, hold down the button to rapidly change frequencies, and release it.

To automatically search for the next lower or higher station, hold down TUNING ( FREQ on the remote control) until the display starts to change, then release it. The receiver searches down or up the band to the next strong station.

Notes:

TUNED appears when you receive a strong signal.

If you press TUNING at the top of the frequency range or TUNING at the bottom of the frequency range, the display returns to the other end of the range.

Direct Access Tuning (Remote Control Only)

Follow these steps to directly enter a frequency.

1.Press FM/AM (BAND on the remote control) to select the tuner. Then press FM/AM (BAND) again to select the desired band. The receiver tunes to and displays the frequency last selected in that band.

2. Press DIRECT ACCESS. _ _ _ _ _ _ _ _ appears on the display with the first _ _ flashing.

3. Enter the desired frequency using the number buttons.

Notes:

If you enter an invalid frequency (for example, entering 828), the receiver tunes to the closest valid frequency (830 kHz).

If you do not press a key within 5 seconds, the receiver exits direct access tuning. Start over at Step2.
