S 3 5 0 DL O PE RATI ON M AN UAL

• The telescopic antenna does not have to be
extended for AM reception. The radio has an
internal, directional, ferrite-bar antenna for
AM reception.
• To optimize AM reception, swivel the radio
until maximum signal strength is achieved.
THE FREQUENCY LOCK
FEATU RE
The S350DL uses a unique circuit for AM and SW
tuning to optimize frequency stability and mini-
mize signal drifting. While turning either tuning
knob, ‘Khz’ flashes in the display. It stops flashing
about 3 seconds after a station is tuned-in,
engaging frequency-lock.
TUNING IN AM STATIONS (MW)
Turn on the radio and set the AM/SW BAND
switch to the AM position and the bandwidth
switch to wide or narrow. MW appears in the dis-
play. Use the outer ‘fast’ tuning knob to find sta-
tions, fine tuning with the inner ‘slow’ knob when
needed.
• If there is interference from adjacent
stations, place the BAND WIDTH control in the
NARROW position. If there is no interference,
leave it in the WIDE position.
• If there is excess background noise, turn on
the SW LPF switch, which may minimize
the noise.
• If a station is so strong that audio distortion
occurs, reduce the gain level with the AM/SW
RF GAIN control knob by turning it counter-
clockwise.

8 TUNING IN FM STATIONS
Fully extend the telescopic antenna and turn on
the radio. Switch the BAND WIDTH FM AFC selec-
tor to the FM AFC ON position. FM appears in the
display, as well as FM frequency numbers in the
range of about 87-108 megahertz, abbreviated
MHz. Use the outer ‘fast’ tuning knob to find sta-
tions, fine tuning with the inner ‘slow’ knob when
needed. When Automatic Frequency Control (AFC)
is ON, strong signals will automatically be cap-
tured and given precedence over weaker ones.
With AFC turned OFF, the weak stations inbe-
tween stronger ones will be tuned in easier.AFC
ON is generally the preferred position.
• Placing the STEREO MONO switch in the
STEREO position enables FM reception
in stereo.
NOTE: The stereo is heard from earphones or
headphones and it is also heard from the stereo
line-level outputs when feeding their output to
amplified speakers or a stereo system.
• Placing the STEREO MONO switch in the
MONO position will improve the quality of a
poorly received station, but it will not be
heard in stereophonic sound from the line
level outputs.
• When listening through the built-in speaker,
stereophonic sound is not heard. Only monau-
ral sound is heard from the built-in speaker.
• If a station is not being received clearly,
swiveling the telescopic antenna may result in
improved reception.
