PREPARATION
You can power your SCP-98 from any of three power sources:
• Internal battery power
• Standard AC power (with an optional AC adapter)
• Vehicle battery power (with an optional DC adapter)
Note: Connecting an adapter disconnects internal batteries.
USING INTERNAL BATTERY POWER
You can power your SCP-98 from two AA batteries (not sup-
plied). For the best performance, we recommend alkaline bat-
teries, such as RadioShack Cat. No. 23-557. You can also use
rechargeable nickel-cadmium batteries (Cat. No. 23-125) with
a battery charger (Cat. No. 23-133).
(illus)
1. Press down on the battery compartment cover and slide
it in the direction of the arrow until it stops, then lift up the
curved edge of the cover (opposite the arrow).
Caution: The battery compartment cover is attached to
the SCP-98 by a hinge. Do not attempt to remove the
cover completely.

5
2. Put the batteries into the compartment as indicated by
the polarity symbols (+ and –) marked inside, with the
back battery over the attached ribbon. 12:00 AM
appears.
Cautions:
• Use only fresh batteries of the required size and rec-
ommended type.
• Do not mix old and new batteries, different types of
batteries (standard, alkaline, or rechargeable), or
rechargeable batteries of different capacities.*
3. Close the cover.
When the SCP-98 stops operating properly, replace the bat-
teries. To prevent stored stations from being lost, set STEREO/
MONO/TAPE to TAPE before replacing batteries.
Cautions:
• If you do not plan to use the SCP-98 with batteries for a
month or more, remove the batteries. Batteries can leak
chemicals that can destroy electronic parts.
• Dispose of old batteries promptly and properly. Do not
burn or bury them.
Notes:
• To easily remove the batteries, open the battery compart-
ment cover and pull up the ribbon.

6
• Your SCP-98 is capable of using rechargeable nickel-
cadmium batteries. At the end of a nickel-cadmium bat-
tery’s useful life, it must be recycled or disposed of prop-
erly. Contact your local, county, or state hazardous waste
management authorities for information on recycling or
disposal programs in your area. Some options that might
be available are: municipal curbside collection, drop-off
boxes at retailers such as your local RadioShack store,
recycling collection centers, and mail-back programs.
USING STANDARD AC POWER
You can power the SCP-98 from standard AC power using an
optional AC adapter, such as Cat. No. 273-1654.
Cautions:
• The recommended AC adapter supplies 3 volts and
delivers at least 300 milliamps. Its center tip is set to neg-
ative, and its plug correctly fits the SCP-98’s DC 3V jack.
Using an adapter that does not meet these specifications
could damage the SCP-98 or the adapter.
• Always plug the AC adapter into the SCP-98 before you
plug it into the AC outlet and always unplug it from the
AC outlet before you unplug it from the SCP-98.
Download from Www.Somanuals.com. All Manuals Search And Download.
7
Follow these steps to power the SCP-98 from a standard AC
outlet.
(illus)
1. Set the AC adapter’s voltage switch to 3V.
2. Put the adapter’s 3.4 mm outer diameter/1.3 mm inner
diameter barrel plug onto the adapter cord’s small end so
it reads TIP–.
3. Insert the barrel plug into the SCP-98’s DC 3V jack.
4. Plug the AC adapter’s other end into a standard AC out-
let. 12:00 AM appears.
USING VEHICLE BATTERY POWER
You can power the SCP-98 from a vehicle’s cigarette-lighter
socket using an optional DC adapter, such as Cat. No. 270-
1560 or 273-1810.
Download from Www.Somanuals.com. All Manuals Search And Download.
8
Cautions:
• The recommended DC adapters supply 3 volts and
deliver at least 300 milliamps. Their center tips are set to
negative, and their plugs correctly fit the SCP-98’s DC 3V
jack. Using a DC adapter that does not meet these spec-
ifications could damage the SCP-98 or the adapter.
• Always plug the DC adapter into the SCP-98 before you
plug it into the vehicle’s cigarette-lighter socket, and
always unplug it from the cigarette-lighter before you
unplug it from the SCP-98.
• Unplug the adapter from your vehicle’s cigarette-lighter
socket when you turn off the ignition. This prevents your
vehicle’s battery from being drained if you leave the SCP-
98 on when you turn off the ignition.
Follow these steps to power the SCP-98 from your vehicle’s
battery power.

2. Put the 3.4 mm outer diameter/1.3 mm inner diameter
barrel plug onto the adapter cord’s smaller end so it
reads TIP–.
3. Insert the barrel plug into the SCP-98’s DC 3V jack.
4. Plug the DC adapter’s other end into the vehicle’s ciga-
rette-lighter socket. 12:00 AM appears.
CONNECTING HEADPHONES/
SPEAKERS
To listen to the cassette player, you need a pair of stereo
1
headphones or amplified speakers with a /8-inch plug. Your
local RadioShack store sells a wide variety of headphones
and amplified speakers.
Insert the stereo headphones’ or speakers’ 1/8-inch stereo
plug into the SCP-98’s PHONES jack.

Listening Safely
To protect your hearing, follow these guidelines when you use
headphones.
• Set the volume to the lowest setting before putting on the
headphones. After you put on the headphones, adjust
the volume to a comfortable level.
• Do not listen at extremely high volume levels. Extended
high-volume listening can lead to permanent hearing
loss.
• Once you set the volume, do not increase it. Over time,
your ears adapt to the volume level, so a volume level
that does not cause discomfort might still damage your
hearing.
Traffic Safety
Do not wear headphones while operating a motor vehicle or
riding a bicycle. This can create a traffic hazard and could be
illegal in some areas.
Even though some headphones let you hear some outside
sounds when listening at normal volume levels, they still can
present a traffic hazard.

SETTING THE 10KHZ/9KHZ SWITCH
The 10kHz/9kHz switch on the back of the cassette compart-
ment door is preset to 10kHz. At this setting, the SCP-98 dis-
plays the time in the 12-hour format and tunes frequencies in
increments of 10 kHz (AM) and 0.1 MHz (FM), which are stan-
dard in the United States.
In Europe and some other parts of the world, AM and FM fre-
quencies are broadcast in increments of 9 kHz (AM) and 0.05
MHz (FM). If you use the SCP-98 in these countries, use a
pointed object, such as a straightened paper clip, to set 10kHz/
9kHz to 9kHz.

CARE AND MAINTENANCE
Your Optimus SCP-98 AM/FM Stereo Cassette Player is an
example of superior design and craftsmanship. The following
suggestions will help you care for the SCP-98 so you can en-
joy it for years.
Keep the SCP-98 dry. If it gets wet, wipe it dry im-
mediately. Liquids might contain minerals that
can corrode the electronic circuits.
Use and store the SCP-98 only in normal temper-
ature environments. Temperature extremes can
shorten the life of electronic devices, damage
batteries, and distort or melt plastic parts.
Keep the SCP-98 away from dust and dirt, which
can cause premature wear of parts.
Handle the SCP-98 gently and carefully. Drop-
ping it can damage circuit boards and the case
and can cause the SCP-98 to work improperly.
Wipe the SCP-98 with a damp cloth occasionally
to keep it looking new. Do not use harsh chemi-
cals, cleaning solvents, or strong detergents to
clean the SCP-98.
Modifying or tampering with the SCP-98’s internal compo-
nents can cause a malfunction and might invalidate its warran-
ty and void your FCC authorization to operate it. If your SCP-
98 is not performing as it should, take it to your local
RadioShack store for assistance.

RESTORING TAPE TENSION AND
SOUND QUALITY
After you play a cassette several times, the tape might be-
come tightly wound on the reels. This can cause playback
sound quality to deteriorate.
To restore the sound quality, fast-forward the tape from the
beginning to the end of one side, then turn the tape over and
fast-forward to the end again. Then loosen the tape reels by
gently tapping each side of the cassette’s outer shell on a flat
surface.
Caution: Be careful not to damage the cassette when tapping
it. Do not touch the exposed tape or allow any sharp objects
near the cassette.
CLEANING THE TAPE-HANDLING
PARTS
Dirt, dust, or particles of the tape’s coating can accumulate on
the tape heads and other parts that the tape touches. This can
greatly reduce the performance of the SCP-98. Use the follow-
ing cleaning procedure after every 20 hours of operation.
1. Remove the batteries and disconnect any other power
source.
2. Open the cassette compartment door.
3. Press
to expose the tape-handling parts.
