Radio Shack DX-398 owner manual Direct Access Tuning, Scan Tuning

If you set STEP to FAST, the tuning in- crements are the same as when you

press TUNING or . If you select SLOW, the tuning increments are smaller so you can fine tune the fre- quency.

Band	Fast	Slow
FM	0.1 MHz	0.05 MHz
LW	9 kHz	1 kHz
MW	9/10 kHz	1 kHz
SW	5 kHz	1 kHz
AM Mode	1 kHz	40 Hz
set to USB
or LSB

Note: You can tune standard AM, up- per sideband (USB), and lower side- band (LSB) frequencies. For more information, see “Tuning SSB Sta- tions” on Page 25.

If you set STEP to STOP, turning MAN- UAL TUNING has no effect at all, so you cannot accidentally change the frequency.

Note: Setting STEP to STOP locks only MANUAL TUNING. For information about locking the front panel buttons, see “Locking the Controls” on Page 15.

Scan Tuning

To automatically tune up or down to the next active frequency in the select-

ed band, hold down TUNING or for about 1 second. The receiver scans up or down the selected band and tunes to the first frequency it finds

with a strong signal.

To scan for an SW (shortwave) fre- quency in one of the 14 meter bands, press SW, press the number button with the meter range you want to scan,

then press TUNING or to scan the band.
