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.
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

see “Locking the Controls” on
Page 15.
