Station Tuning
First, select desired band by
pressing one of the AM or FM
station buttons (3), then tune
manually by turning control knob (4).
For good reception, accurate
manual tuning is important.
To preset stations on pushbutton
tuning radios in either the AM or
FM band, pull station buttons (3),
carefully tune in the desired station,
push button slowly and firmly all
the way in, then release.
Automatic station tuning (on signal
seeking radios only) is accompli­
shed by momentarily depressing the
" Automatic Tuning" bar (6). The
tuner moves from the left towards
the right side of the dial and stops
whenever a useable station is found.
Operating the automatic tuning bar
again causes the tuner to resume its
search function. When the end of
the band is reached, the tuner will
automatically return to the be­
ginning of the band and start the
search operation again.
The position of the search sensitivity
switch (5) determines whether the
tuner will stop at many or the most
powerful stations only.
Position I Selector stops at every
" country" useable station
Position II Selector stops only at
" suburb" more powerful stations
Position III Selector stops only at
" city" the strongest stations
