4 CONNECTING TO POWER
USING BATTERIES
Open the battery compartment and insert 4 size 0
batteries (also called UM-l) according to the
polarity diagram imprinted on the battery com-
partment 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 dis-
torted, replace the batteries.
• 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 ifit is to be stored
for long periods without use.
• 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 radio. Only use the adaptor that is supplied
with the S350DL or one that meets the generic
specifications required by this product: output of
6
volts, DC, negative polarity; plug-tip outer diam-
eter of 5.5 millimeter, inner diameter of 2.1 mil-
limeter; capable of 300 milliamperes or greater.
Contact Eton 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 DAM-
AGE NOT COVERED BY WARRANTY .

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 plug-tip is pluggE!d into the radio's DC jack.
It must be capable of handling at least 200
milliamperes of current. Contact Et6n for the
name and location of a retailer that sells the
proper converter.

5 SETTING THE PRELIMINARY CONTROL SETTINGS
Use these controls as initial gUidelines. As you get
to know the radio, you will develop your own
'favorite' settings.
• Tum the VOLUME control down to no
greater than 3 so that the radio does not play
loudly when first turned on.
• Tum the AM/SW RF GAIN control to the
10 position.
• Turn the BASS- TONE-TREBLE controls into
the 5 position.
• Turn the SW LPF switch to the OFF position
(right side of the radio).
• Turn the STEREO MONO switch to the
MONO position.

OPERATION MANUAL
6 TURNING THE RADIO ON AND OFF
There are two ways to turn the radio on, with the
gO-minute timer feature or without the gO-minute
timer. To turn it off at any time, press the 'POWER
& SLEEP' button for about one second.
NOTE: When SLEEP TImes is off, the clock
always shows in the display.
1. WITH TIMER: A quick, short press of the
'POWER & SLEEP' button turns the radio on.
'90' shows in the display for about three sec-
onds, then the radio's normal frequency dis-
play shows. Turning it on this way causes it
play for 90 minutes, after which its timer turns
it off automatically (to minimize excess bat-
tery drain). To change this automatic turn-off
time from 90 minutes to a shorter time, see
the section titled USING THE SLEEP TIMER.
2. WITHOUT TIMER: A long press of approxi-
mately 3 seconds of the 'POWER & SLEEP'
button turns the radio on without engaging
the automatic 90-minute timer feature, caus-
ing the radio to play indefinitely when using
the AC adaptor, and turning off only when the
batteries drain or the radio is turned off.
When you are listening to stations, the signal
strength meter, in the upper right area of the dis-
play, will show the $trength level of reception.

9 TUNING IN AM STATIONS
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.
OPERATION MANUAL
• 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
FEATURE
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.
•

10 TUNING IN SHORTWAVE STATIONS
IF YOU ARE ALREADY
FAMILIAR WITH SHORTWAVE:
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 sta-
tion is so strong that audio distortion occurs,
reduce the gain level with the AM/SW RF
GAIN control knob by turning it
counter-clockwise.
IF YOU ARE NEW TO SHORT-
WAVE OR NEED A REFRESHER
(also see the section titled INTRODUCTION TO
SHORTWAVE, later in this manual) Fully extend
the telescopic antenna and turn on the radio.
Get close to a window and fully extend the tele-
scopic antenna. Follow the instructions below,
depending on day or night listening.
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 listening for stations.
Also try the 13 meter band (21450-21850 KHz)
and 16 meter band (17480-17900 KHz),
both in SW3.
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 stations. 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).
NOTE: If there is interference from adjacent sta-
tions, place the BAND WIDTH control in the NAR-
ROW position. If there is no interference, leave it
in the WIDE position. If there is excess back-
ground 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.
The Frequency lock feature, described on page
13, also works with shortwave.

11 SETTING THE CLOCK

button and BACKLIGHT button)
4. Moreover, when the radio turns on, rotate
the tuning knob (fast & slow) can also turn on
the backlight for 8 seconds.
CAUTION: leaving the backlight permanently
on will drain the batteries more rapidly.
• The display shows random characters or
does not work properly although the radio
can receive stations normally.
In these cases, you might need to reset the radio.
To reset the S350DL, unplug the external adaptor
(if one is being used) and remove the batteries
from the battery compartment. Insert a pointed
object, such as straightened paper clip, into the
RESET hole on the right, front side of the radio
and gently press and release the button inside the
hole. Then plug in the AC adaptor or reinstall the
batteries.

with audio line level inputs. The output is stereo
when the radio is tuned to an FM station broad-
casting in stereo.

OPERATION MANUAL
18 USING SUPPLEMENTARY ANTENNAS
SHORTWAVE ANTENNAS. This radio can be
used with basic, 10n£1 wire antennas and other
high impedance shortwave antennas (optimally
500 ohm). The length of a long-wire 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-conductive
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.
AM ANTENNAS: Any high impedance (opti-
mally 500 ohm) AM antenna can be used, includ-
ing long-wires and tuned loops. A ground wire, as
discussed under SHORTWAVE ANTENNAS, 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 part number 278-265).

19 INTRODUCTION TO SHORTWAVE
Shortwave enables you to hear stations from
around the world. Now that you have a short-
wave 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

HOW TO IDENTIFY WHAT
YOU'RE LISTENING TO AND
HOW TO FIND STATIONS THAT
YOU WANT TO HEAR
We recommend the use of a comprehensive
shortwave directory, especially if you want to hear
specific countries or to identify the station you're
listening to. Such a directory will alphabetically
list the countries broadcasting on shortwave,
