Gently place the radio on its front with the bottom facing you.
Remove the battery/cord storage compartment door by releasing the three

compartment door latches, then swing door toward you and off.
Insert the 6 “D” size batteries into the compartment as indicated on the panel

inside the compartment. Be sure the + (cap) end of each battery is installed
in t he direction shown in the battery outline. Insert’ ‘bottom row” of batteries
first, then slide the “top row” under the BATTERY STRAP from the left side

BAITERIES

Replace the compartment door by first

placing

the bottom securing tabs into

their receptacles; then swing

doo}

into

positi&

and press until

th;three

lat-

ches “snap” into place.
NOTE. After a portable radio has been used extensively in battery operation,

the qualify of the sound may deteriorate or the loudness may decrease.
When this happens, the very first thing to suspect is rundown batteries.

Further confirmation that the batteries are run down can be made by
changing to AC tine cord operation. If the sound quality improves the
batteries are run down and should be replaced with new batteries.

Your SUPERRADIO offers exceptional battery life with standard “D” size bat­teries. Alkaline batteries, although more expensive, offer increased battery life
over standard cells.

IMPORTANT
Since few batteries are actually “leakproof”, always remove batteries, (even if
new) when storing product unused for over 30 days or using AC continually. For
shorter periods of AC operation (up to 30 days) batteries may remain in product.

Always remove worn-out batteries as they may leak chemicals which

will

damage

the electronic components and cabinet. When discarding

baUeries,

be sure to

dispose of them in the proper manner, according to your state and

local

regulations.

120-VOLT AC OPERATION

Remove

&wer

cord from COrTptirWIt and plug into any 120-volt AC household

outlet. An opening in the compartment door

has been

provided to permit AC
operation with the door in place. Your radio will automatically convert from bat­tery to AC operation. When finished using radio on

AC,

be sure to Switch POWER

ON-OFF switch to OFF. Removing plug from household outlet without

switching

radio to OFF will automatically revert operation to battery power.

level and tone.

To turn radio off, press the POWER ON-OFF switch again.

AM BAND

AM Band radio stations are assigned broadcast frequencies between 540 and
1700 Kilohertz (KHz). AM transmissions leave the antenna in two types of radio
waves - ground waves and sky waves. Ground waves stay close to the ground
and can be picked up by receivers in the local area. Sky waves go into the sky
and pass thru the ionosphere into

outer

space. Some sky waves have a tenden­cy to “bounce” back from the ionosphere (especially during the evening hours)
and can be picked up by distant receivers.

strong

local stations when in the WIDE positon,

NOTE:

In the WIDE position, you may encounter beat and whistle noises due

to adjacent-channel stations in the AM band. This problem maybe par­ticularly noticeable during nighttime reception. If this occurs, switch to
NORMAL positon.

FM BAND

FM Band radio stations broadcast on assigned frequencies between 88 and 108

Megahertz (MHz), FM broadcasts are higher frequencies and offer less static
and interference from outside sources as well as greater audio fidelity than AM
broadcasts. Range, however, is not as great as AM because very little, if any,
sky-wave reception is involved at FM frequency range.

AFC (Automatic Frequency Control)

Automatic Frequency

Conrol (AFC)

works to assure drift-free FM reception and

helps to keep the radio locked-in on

the

station to which it is tuned. AFC works
only on FM, it does not affect the AM operation. Tune to the desired FM station
with the AFC SELECT switch in ON position.

Under certain conditions, you may not wish to use the AFC. When the desired
station frequency is adjacent to a stronger station, the Automatic Frequency Con­trol may tune the set to the stronger station. If this occurs, tune in the desired
station with the AFC switch in OFF position. Should switching to ON cause the
set to detune to the stronger adjacent station, simply leave the AFC SELECT
switch in OFF position.

BASS/TREBLE CONTROLS

The BASS control enable you to increase or decrease the relative volume of the
low-pitched (bass) sounds from the normal (or “flat”) control setting.

The TREBLE control enables you to increase or decrease the relative volume
of the high pitched (Treble) sounds from the normal (or “flat”) control setting.

NOTE: These Tone Controls have a large built-in variation range which will enable

you to emphasize the various tonal sounds and alter the music you are
receiving. You may be able to vary the musical balance of the music

POWER ON-OFF SWITCH

The convenient Power ON-OFF push button switch enables you to set the
VOLUME, BASS and TREBLE controls, then turn the radio on or off without having

to reset the controls each time.

BUILT-IN AM/FM ANTENNAS

AM

— The BUILT-IN ANTENNA (200 mm Ferrite Rod) is somewhat directional,

and on weak stations it may be

necessaty

to rotate the radio for beat reception.

The FM WHIP antenna is not used for AM reception.
FM — The WHIP ANTENNA maybe positioned anywhere within an 180 degree

arc and is capable of rotating 380 degrees. To use, lift and extend the WHIP to
its fullest length. For distant stations, it may be necessary to adjust the WHIP
antenna’s position for beat reception.

NOTE: To avoid damaging the WHIR always lower its sections one at a time

star-

ting

with the largest diameter. Never lower the WHIP from the tip end
since buckling or bending is possible. Be sure the slot provided in the
base of the

swivel

antenna is positioned properly before lowering the WHIP

into its holder clip.

WHIP ANTENNA REPLACEMENT

The whip antenna has been designed so that it is easily replaced in the event
it is damaged. The antenna’s mounting post goes through a hole in the cabinet
top and is held in place by a single screw through the catinef back. Simply remove
the screw and slide the post out of the cabinet top. To install the replacement,
reverse the procedure.

To order a replacement whip antenna (No. 5-1992) use Accessory Order Form
included in this Guide.

EXTERNAL AMIFM

ANTENNA TERMINALS

Although the

Superadio

normally provides excellent reception utilizing its

built-

in antennas, it offers the additional capability of connecting outside AM or FM
antennaa to the EXTERNAL ANTENNA terminals on the cabinet back. External
antennae

can be used in poor reception areas (inside steel and concrete buildings)

or to improve

recemlon

of dktant stations. The antenna required for FM differs

from the type needed for AM reception.
AM -An AM antenna for outside installation connects to the screw terminals on

the cabinet back marked

AM and

GND.

FM - You

may

use

vour

TV antenna or an

outside FM antenna. The twin leads

connect to the

scr&v

terminals marked FM (300 ohm) and GND.

IMPORTANT External antennae are available

EXCESSIVELY NOISY RECEPTION

The “noise” may becoming from outside sources such as the broadcast pro­gram material, electrical “noise” from nearby automobiles, electrical lights
(fluorescent lamps),

ets.,

also, noise will be more noticeable from distant

stations.

LONG DISTANCE AM LISTENING

(DXing)

Because your

Superadio

Ill is designed for long-range AM

recewlon

you will gain
added enjoyment receiving broadcasts from dietant AM stations. You may listen
to newa, weather,

spor@

and other special programming from ofher cities. A station

log has been included on page 6 to help you keep a DX (long distance recep-

tion) record of stations received.

Although daytime

AM reception is limited to a maximum of a few hundred miles
(depending on the strength of the radio station, atmospheric conditions, etc.),
at night you maybe able to pick up powerful stations over a thousand miles away.
This is because AM “sky-wave” signals are reflected off the ionosphere and back

to earth in the nighttime

hours.

OX HELPFUL HINTS

The number of stations you are able to receive is a function of many factors.
The following may prove helpful:

1. Although the built-in AM antenna will enable you to receive many distant sta-

tions, your reception can be improved significantly with the addition of an
external AM antenna.
