S350DL or one that meets the generic specifications
required by this product: output of 6 volts, DC, nega-
tive polarity; plug-tip outer diameter of 5.5 millimeter,
inner diameter of 2.1 millimeter; capable of 300 mil-
liamperes or greater. Contact Etón for the name and
location of a retailer that sells the proper adaptor.
NEVER USE AN ADAPTOR THAT DOES NOT MEET
THESE SPECIFICATIONS, AS IT MAY CAUSE DAMAGE
NOT COVERED BY WARRANTY.
USING BATTERIES
Open the battery compartment and insert 4 size D
batteries (also called UM-1) according to the polar-
ity diagram imprinted on the battery compartment
floor.
Please note the following regarding
battery operation:
• The S350DL has a battery power indicator in
the LCD. Fresh batteries will show a full power
level of three bars. If the indicator shows only one
bar or the sound becomes week and distorted,
replace the batteries.
POWERING FROM A CAR OR BOAT 12 VOLT DC
BATTERY SOURCE
This requires a DC converter that converts the 12 volt
DC source to the 6 volts required by the radio. The
output of such an adaptor is 6 volts, DC, negative
polarity. The plug-tip must have an outer diameter of
5.5 millimeter and an inner diameter of 2.1 millimeter.
• The radio will turn off automatically if the
batteries become too weak.
• Check the batteries periodically for leakage.
As a precaution, remove the batteries to
prevent possible leakage if it is to be stored for
long periods without use.
The plug-tip is plugged into the radio’s DC jack.
It must be capable of handling at least 200
milliamperes of current. Contact Etón for the name
and location of a retailer that sells the proper con-
verter.
• Turn off the radio while replacing the batteries.
USING AC POWER
The S350DL is supplied with an AC adaptor that
converts AC voltage to the DC voltage used by the

6 TURNING THE RADIO ON AND OFF
There are two ways to turn the radio on, with
the 90-minute timer feature or without the
90-minute timer. To turn it off at any time,
press the ‘POWER & SLEEP’ button for about
one second.
way causes it play for 90 minutes, after which
its timer turns it off automatically (to minimize
excess battery drain). To change this automatic
turn-off time from 90 minutes to a shorter time,
see the section titled USING THE SLEEP TIMER.
Note: When SLEEP Times is off, the clock
always shows in the display.
2. WITHOUT TIMER: A long press of approxi-
mately 3 seconds of the ‘POWER & SLEEP’ button
turns the radio on without engaging the auto-
matic 90-minute timer feature, causing the radio
to play indefinitely when using the AC adaptor,
and turning off only when the batteries drain or
the radio is turned off.
1. WITH TIMER: A quick, short press of the
‘POWER & SLEEP’ button turns the radio
on. ‘90’ shows in the display for about
three seconds, then the radio’s normal
frequency display shows. Turning it on this
7 SIGNAL STRENGTH INDICATOR
When you are listening to stations, the signal strength meter, in the upper right area of the display, will show
the strength level of reception.
8 TUNING IN FM STATIONS
Fully extend the telescopic antenna and turn on the
radio. Switch the BAND WIDTH FM AFC selector 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 stations, fine
tuning with the inner ‘slow’ knob when needed.
When Automatic Frequency Control (AFC) is ON,
strong signals will automatically be captured and
given precedence over weaker ones. With AFC
turned OFF, the weak stations inbetween stronger
ones will be tuned in easier. AFC ON is generally the
preferred position.
• 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 stereo-
phonic sound from the line level outputs.
• When listening through the built-in speaker,
stereophonic sound is not heard. Only monaural
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.
• 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.

9 TUNING IN AM STATIONS
• The telescopic antenna does not have to be
extended for AM reception. The radio has an inter-
nal, directional, ferrite-bar antenna for AM reception.
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 display. Use the
outer ‘fast’ tuning knob to find stations, fine tuning
with the inner ‘slow’ knob when needed.
• To optimize AM reception, swivel the radio until
maximum signal strength is achieved.
THE FREQUENCY LOCK FEATURE
• 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.
The S350DL uses a unique circuit for AM and SW
tuning to optimize frequency stability and minimize
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.
• 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.
10 TUNING IN SHORTWAVE STATIONS
depending on day or night listening.
IF YOU ARE ALREADY
FAMILIAR WITH SHORTWAVE:
If it is daytime, turn the AM/SW BAND switch to the
SW2 position. Use the fast tuning knob and tune to
15100 KHz. This is the beginning of the shortwave
19 meter band, one of the three best daytime bands,
extending from 15100-15600 KHz. Using the slow
tuning knob, tune through this band, carefully listen-
ing for stations. Also try the 13 meter band (21450-
21850 KHz) and 16 meter band (17480-17900 KHz),
both in SW3.
Fully extend the telescopic antenna and turn on
the radio. Set the AM/SW BAND switch to the SW1,
SW2 or SW3 position and the BANDWIDTH switch
to wide or narrow. SHORTWAVE 1, 2 or 3 appears
in the display. Use the outer ‘fast’ tuning knob to
quickly go to a desired frequency that you already
know or to the band that you want to tune around
in, then fine tune stations with the inner ‘slow’ knob
when needed. 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
If it is night, turn the AM/SW BAND switch to the SW1
position. Use the fast tuning knob and tune to 5800
KHz. This is the beginning of the shortwave 49 meter
band, one of the four best night bands, extending
from 5800-6200 KHz. Using the slow tuning knob,
tune through this band, carefully listening for sta-
tions. Also try the 25 meter band in SW2 (11600-
12200 KHz), 31 meters in SW2 (9400-9900 KHz)
and 41 meters in SW1 (7150-7600 KHz).

This radio can be used with basic, long wire anten-
nas and other high impedance shortwave anten-
nas (optimally 500 ohm). The length of a long-wire ground wire, as discussed under SHORTWAVE ANTEN-
Any high impedance (optimally 500 ohm) AM antenna
can be used, including long-wires and tuned loops. A
antenna should be anywhere from about 30-100
feet (10-30 meters). Best performance is from
copper wire. The antenna should be above ground,
preferably running in a straight line. Non-conduc-
tive insulators should be used on both ends of the
wire to prevent signal loss. The wire is plugged into
the red colored spring socket, AM,SW ANT., on the
back of the radio. Connecting a ground wire to the
black spring socket, GND, often helps reception,
but is not mandatory. The ground wire should be
connected to a cold water pipe or a ground rod. If
no water pipe or ground rod is available, connect a
wire about the same length as the antenna wire
and lay it on the ground. NEVER CONNECT THE
GROUND WIRE TO A GAS PIPE.
NAS, is even more helpful during AM reception and
often improves reception considerably, even when no
supplementary AM antenna is used.
FM ANTENNAS
Connect FM antennas to the FM ANT. CABLE FM
socket on the back of the radio. These antennas should
have an impedance of 75 ohms. Most antennas fed
with coaxial cable are 75 ohm antennas. If your coaxial
cable has a ‘F’ plug, like that used on North American
TV’s and VCR’s, use a F to PAL converter plug to fit the
European style PAL socket on the radio. (Radio Shack

you’re an experienced shortwave listener, you’ll
already know what bands are and how to use them,
but if you’re new, you’ll need to learn about bands
first. After that, you will have excellent success.
Please read on.
Shortwave enables you to hear stations from
around the world. Now that you have a shortwave
radio, no doubt you’ll want to hear
worldwide stations right away. If you’re new to
shortwave, please take some time to learn the
basics outlined below. To successfully listen to
shortwave stations you must know how to find

25m, 31m and 49m. Just like in AM and FM radio,
one simply gets into the shortwave band and tunes
around, looking for stations.
TO FULLY ENJOY SHORTWAVE LISTENING,
THIS IS THE MOST IMPORTANT CONCEPT TO
LEARN RIGHT AWAY.
If you have ever listened to AM or FM radio, then
you already know what a band is. The AM band is
a frequency range stretching form 530 to 1600
kilohertz, the FM band is 88-108 megahertz. A
band is simply a frequency range where stations are
located. When you look for stations in these ‘bands’,
you simply tune around with the tuning knob until
you find a station you like. Shortwave is similar and
the shortwave bands have names like 25 meters,
31 meters, 49 meters, etc. These are abbreviated
For example, the 19 meter shortwave band encom-
passes the frequency range of 15100 to 15600
kilohertz. On the next page is a list of the shortwave
bands used for international shortwave broadcasts
and their corresponding frequency ranges. Since
some radios show frequency in megahertz and
some in kilohertz, both are shown here. The S350DL

good into the early night.
Because shortwave signals depend on such factors
as the sun, the ionosphere and interaction with the
earth itself, signals cannot be heard on all bands
throughout the day. Some bands are best during
the daylight hours, and some are best at night. Here
are some good ‘rules of thumb’.
• While most shortwave stations are found
within the frequency limits of these defined
bands, some are found outside of them. It pays to
take the time to tune in-between bands too.
• In general, the bands with frequencies

are not dependent on location.
below 13000 KHz are better at night and the
bands with frequencies above 13000 KHz are
best during the day. This guideline is not ‘cast in
concrete’ but is a useful general rule of thumb.
Listed on the next page are the characteristics of
the major shortwave bands. Follow these guidelines
for best listening results.
• Around sunrise and sunset, both the day
and night bands might be good, sometimes
24 DAYTIME LISTENING
Shortwave listening is generally at its poorest during the daylight hours of about two hours after sunrise
until about two hours before sunset. The major reason for this is that the broadcasters are not transmitting
to North America at this time, assuming that we are all either at work or at school and are not able to listen
during the day. If you want to try daytime listening, use the guidelines below. Typically, daytime shortwave
tends to be better in Eastern North America than in Western North America.

This is the best time to listen, because the broadcasters are deliberately transmitting to North America.
These bands may be extremely good around sunset and sunrise too.

IMPORTANT NOTE: Getting close to a window may substantially improve your reception. The construction
materials of some buildings simply do not let signals in very well. Signals penetrate wood frame buildings
easiest, while concrete and brick buildings usually block signals. If you are in a building with one or more
stories above you, signals can also be impaired in strength. In such a situation, situate the radio as close to a
window as possible while listening. Holding the radio while close to a window may also improve reception.
