FEATURES
Your Optimus SCP-87 Digital AM/FM Stereo Cassette Player delivers excellent stereo sound through
your headphones or amplified speaker system. Because the SCP-87 is portable, you can listen to cassette tapes or the AM/FM radio indoors or out.
Important: To listen to your SCP-87, you need a pair
of headphones or amplified speakers (not supplied)
with a 1/8-inch mini-plug. Your local RadioShack
store sells many headphones and speakers.
This player’s features include:
PLL (Phase-Locked Loop) Tuning — gives you
precise tuning and drift-free reception.

continuously play both sides of a cassette tape.
Tape Direction Control — lets you change the
tape’s direction to play the other side at any time
without having to eject the tape and turn it over.
Display — shows the currently tuned station.

PREPARATION
BEFORE YOU BEGIN
To protect the playback head
during shipment, a protective
sleeve is attached. Remove it
before you use the SCP-87’s
cassette player.
CONNECTING TO POWER
You can power your SCP-87 from:
• Internal batteries
• AC power (using an AC adapter)
• Your vehicle’s battery (using a DC adapter)
Using Battery Power
The SCP-87 can use two AA batteries for power. For
the best performance and longest life, we recommend alkaline batteries, such as RadioShack Cat.
No. 23-557.
You can also use rechargeable nickel-cadmium batteries (Cat. No. 23-125). These batteries (and a battery charger, Cat. No. 23-133) are available at your
local RadioShack store.
6
14-1230.fm Page 7 Friday, July 2, 1999 10:26 AM
Caution: Do not mix old and new batteries, different
types of batteries (standard, alkaline, or rechargeable), or rechargeable batteries of different capacities.
Follow these steps to install batteries.
1. Open the battery compartment cover by pressing down and sliding it in the direction of the
arrow on the cover, then lifting open the cover.
Caution: The battery compartment cover is
hinged. Do not try to remove it.
2. Insert the batteries into the compartment as indicated by the polarity symbols (+ and –) marked
outside the compartment.
3. Close the cover.
7
14-1230.fm Page 8 Friday, July 2, 1999 10:26 AM
If the BATT indicator becomes dim during operation
or does not light when you turn on the SCP-87, replace (alkaline) or recharge (nickel-cadmium) both
batteries.
Caution: Always dispose of old batteries promptly
and properly.
Important: This product is capable of using rechargeable nickel-cadmium batteries. At the end of
the batteries’ useful life, they must be recycled or disposed of properly. 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.
8
14-1230.fm Page 9 Friday, July 2, 1999 10:26 AM
Using AC Power
To power the SCP-87 from a standard AC outlet, you
need an AC adapter, such as Cat. No. 273-1654.
Cautions:
• You must use an AC adapter that supplies 3
volts DC power and delivers at least 300 milliamps. Its center tip must be set to negative, and
its plug must properly fit the SCP-87’s DC 3V
jack. The recommended adapter meets these
requirements. Using an adapter that does not
meet these requirements could damage the
SCP-87 or the adapter.
• Be sure you connect the adapter to the SCP-87
before you plug it into the AC outlet and that you
unplug the adapter from the AC outlet before you
unplug it from the SCP-87, to prevent damage to
the SCP-87 or the adapter.
9
14-1230.fm Page 10 Friday, July 2, 1999 10:26 AM
Follow these steps to connect the SCP-87 to AC
power.
1. Set the adapter’s voltage switch to 3V.
2. Insert the adapter’s 3.4 mm outer diameter/1.3
mm inner diameter tip into the adapter’s cord, so
it reads –TIP.
3. Insert the plug into the SCP-87’s DC 3V jack.
4. Plug the adapter into a standard AC outlet.
Note: Connecting the AC adapter automatically
disconnects internal batteries.
10
14-1230.fm Page 11 Friday, July 2, 1999 10:26 AM
Using Your Vehicle’s Battery Power
To power the SCP-87 from your vehicle’s battery,
you need a DC adapter, such as Cat. No. 270-1560.
Cautions:
• You must use a DC adapter that supplies 3 volts
DC power and delivers at least 300 milliamps. Its
center tip must be set to negative, and its plug
must properly fit the SCP-87’s DC 3V jack. The
recommended adapter meets these requirements. Using an adapter that does not meet
these requirements could seriously damage the
SCP-87.
• Be sure you plug the adapter into the SCP-87
before you plug it into the cigarette-lighter
socket, and that you unplug the adapter from the
cigarette-lighter socket before you unplug it from
the SCP-87, to prevent damage to the SCP-87
or the adapter.
11
14-1230.fm Page 12 Friday, July 2, 1999 10:26 AM
Follow these steps to power the SCP-87 from your
vehicle’s battery.
.

you are sure it is not working properly.
12
14-1230.fm Page 13 Friday, July 2, 1999 10:26 AM
USING HEADPHONES OR
SPEAKERS
To connect headphones or an amplified speaker system, insert the mini-plug into the SCP-87’s
jack.
Listening Safely
To protect your hearing, follow these guidelines
when you use headphones.
• Set the volume to the lowest setting before you
begin listening. After you begin listening, adjust
the volume to a comfortable level.
13
14-1230.fm Page 14 Friday, July 2, 1999 10:26 AM
• Do not listen at extremely high volume levels.
Extended high-volume listening can lead to permanent hearing loss.
14
14-1230.fm Page 15 Friday, July 2, 1999 10:26 AM
• 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 can be illegal in some areas.
Even though some headphones are designed to let
you hear some outside sounds when listening at normal volume levels, they still can present a traffic hazard.
USING THE BELT CLIP
The belt clip lets you keep your hands free while you
listen to the SCP-87. To attach the belt clip to the
SCP-87, slide the belt clip’s latches into the slots on
15
14-1230.fm Page 16 Friday, July 2, 1999 10:26 AM
the cassette player and slide it up until it locks into
place.
16
14-1230.fm Page 17 Friday, July 2, 1999 10:26 AM
To remove the belt clip from the SCP-87, push in on
PUSH RELEASE, slide the belt clip down, then lift it
off.
SETTING THE FREQUENCY
RANGES AND STEPS
The SCP-87 is set to tune frequencies in steps (increments) of 10 kHz (AM) and 0.2 MHz (FM) as used
in the United States.
In Europe and some other countries, frequency ranges and steps are not the same as those in the United
States. For example:
In North and South America:
AM: 530–1,710 kHz (10 kHz increment)
FM: 87.5–108.1 MHz (0.2 MHz increment)
Note: Actual FM broadcast frequencies are assigned
between 88 and 108 MHz.

14-1230.fm Page 32 Friday, July 2, 1999 10:26 AM
DOLBY NOISE REDUCTION
Your cassette player uses the Dolby B Noise-Reduction system to reduce background noise or tape hiss
on your tapes. When a Dolby-encoded tape is recorded, the Dolby circuit listens to the program material to find soft passages where you might later be
able to hear the tape noise. The Dolby NR system increases the recording level during these passages.
When you play the tape, the circuit reduces the volume of these passages to their original levels and reduces the level of tape hiss to as little as one-third of
the usual noise level.
32
14-1230.fm Page 33 Friday, July 2, 1999 10:26 AM
TAPE TIPS
The following tips can help you get the best performance and the longest life from your SCP-87.
Note: For the best performance, use only regular
length (60- or 90-minute) cassette tapes. We do not
recommend long-playing cassette tapes, such as C120s, because they are extremely thin and can tangle easily.
RESTORING TAPE TENSION AND
SOUND QUALITY
After you play a cassette tape several times, the tape
might become 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 completely rewind it. 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.
33
14-1230.fm Page 34 Friday, July 2, 1999 10:26 AM
CLEANING THE TAPE-HANDLING
PARTS
Dirt, dust, or particles of the tape’s coating can accumulate on the tape heads and other parts the tape
touches. This can greatly reduce the performance of
the SCP-87. To protect the SCP-87, clean the tapehandling parts after about every 20 hours of tape
player operation. Your local RadioShack store sells a
complete line of cassette deck cleaning supplies.
1. Remove the batteries and disconnect any other
power source.
2. Open the cassette compartment cover.
3. Press

CARE AND MAINTENANCE
Your Optimus SCP-87 Digital AM/FM Stereo Cassette Player is an example of superior design and
craftsmanship. The following suggestions will help
you care for the SCP-87 so you can enjoy it for
years.
• Keep the SCP-87 dry. If it gets wet, wipe it dry
immediately. Liquids might contain minerals that
can corrode the electronic circuits.
• Handle the SCP-87 gently and carefully. Dropping it can damage circuit boards and cases and
can cause the system to work improperly.
• Use and store the SCP-87 only in normal temperature environments. Temperature extremes
can shorten the life of electronic devices, damage batteries, and distort or melt plastic parts.
• Keep the SCP-87 away from dust and dirt, which
can cause premature wear of parts.
• Wipe the SCP-87 with a damp cloth occasionally
to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to
clean the SCP-87.
Modifying or tampering with the SCP-87’s internal
components can cause a malfunction and might invalidate the SCP-87’s warranty and void your FCC
authorization to operate it. If your SCP-87 is not performing as it should, take it to your local RadioShack
store for assistance.
