FEATURES
Your Optimus SCP-84 Auto-Reverse AM/FM Stereo Cas-
sette Player delivers excellent sound from its built-in ra-
dio or your favorite cassette tapes through your speakers
or stereo headphones. You can set the time on the cas-
sette player’s display, set an alarm to sound, and store
up to 20 radio stations in memory. The tuner’s PLL
(Phase-Locked Loop) circuitry gives you precise tuning
and drift-free reception.
Its features include:
Auto-Reverse Cassette Deck — lets you continuously
play a cassette tape.
AM/FM Radio with 20-Station Memor
y
— lets you store
up to 20 radio stations (10 FM and 10 AM) in memory so
you can quickly tune to your favorite stations.
LCD with Clock and Alarm — displays the current time
and lets you set the SCP-84 to sound an alarm at the
time you select.

three latches into the corresponding holes on the back of

POWERING THE SCP-84
You can power your SCP-84 from any of three power
sources:
• Internal batteries (not supplied)
• Standard AC power (with an optional AC adapter)
• Your vehicle’s cigarette-lighter socket (with an
optional DC adapter)
Note: Connecting an optional adapter disconnects inter-
nal batteries.
Using Batteries
You can power your SCP-84 from two AA batteries. We
recommend alkaline batteries, such as RadioShack Cat.
No. 23-557, not supplied. You can also use rechargeable
nickel-cadmium batteries (such as Cat. No. 23-125, not
supplied). If you use rechargeable batteries, you also
need a battery charger (such as Cat. No. 23-133, not
supplied).
14-1225.fm Page 6 Friday, July 2, 1999 9:00 AM

7
Cautions:
• Do not mix old and new batteries, different types of
batteries (standard, alkaline, and nickel-cadmium), or
rechargeable batteries of different capacities in the
SCP-84.
• Use only fresh batteries of the required size and type.
Follow these steps to install batteries.
1. Press down on the battery compartment cover and
slide it in the direction of the arrow to remove it.
2. Install the batteries over the ribbon inside the com-
partment as indicated by the positive (+) polarity sym-
bols marked inside.
3. Replace the cover.

Cautions:
• Never leave dead or weak batteries in the SCP-84.
• If you do not plan to use the SCP-84 for a month or
more, or if you plan to use only AC or vehicle battery
power, remove the batteries.
• Dispose of batteries promptly and properly; do not
bury or burn them.
Note: If your SCP-84 locks up, simply remove one of the
batteries then reinstall it.
Important: Your SCP-84 is capable of using recharge-
able 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, recycling collection centers, and mail-
back programs.
Using AC Power
You can power the SCP-84 from a standard AC outlet us-
ing an AC adapter (such as Cat. No. 273-1654, not sup-
plied).
14-1225.fm Page 8 Friday, July 2, 1999 9:00 AM

9
Cautions:
• The recommended AC adapter supplies 3 volts and
delivers at least 300 milliamps. Its center tip is set to
negative, and its plug correctly fits the DC 3V jack on
the bottom of the SCP-84. Using an adapter that
does not meet these specifications could damage the
SCP-84 or the adapter.
• Always plug the AC adapter’s barrel plug into the
SCP-84 before you plug its power module into the
AC outlet, and unplug its power module from the AC
outlet before you unplug its barrel plug from the SCP-
84.
Follow these steps to connect an AC adapter to the SCP-
84.
1. Set the adapter’s voltage switch to 3V.
2. Insert the 3.4 mm outer diameter/1.3 mm inner diam-
eter barrel plug into the AC adapter’s socket. Line up
TIP on the plug with –NEG on the socket.

3. Insert the barrel plug into the SCP-84’s DC 3V jack.
4. Plug the AC adapter into a standard AC outlet.
Using Your Vehicle’s Cigarette-Lighter
Socket
To power the SCP-84 from your vehicle’s cigarette-lighter
socket, you need a DC adapter, such as Cat. No. 270-
1560.
Cautions:
• The recommended DC cigarette-lighter adapter sup-
plies 3 volts and delivers at least 300 milliamps. Its
center tip is set to negative, and its plug correctly fits
the DC 3V jack on the bottom of the SCP-84. Using
an adapter that does not meet these specifications
could damage the SCP-84 or the adapter.
• Unplug the adapter from your vehicle’s cigarette-
lighter socket when you turn off the ignition. This pre-
vents your vehicle’s battery from being drained if you
leave the SCP-84 on when you turn off the ignition.
14-1225.fm Page 10 Friday, July 2, 1999 9:00 AM

11
• Always plug the DC adapter’s barrel plug into the
SCP-84 before you plug its power module into your
vehicle’s cigarette-lighter socket, and unplug its
power module from your vehicle’s cigarette-lighter’s
socket before you unplug its barrel plug from the
SCP-84.
Follow these steps to power the SCP-84 from your vehi-
cles’s cigarette-lighter socket.
1. Set the adapter’s voltage switch to 3V.
2. Insert the 3.4 mm outer diameter/1.3 mm inner diam-
eter barrel plug into the DC adapter’s socket. Line up
negative (–) on the plug with TIP on the socket.
3. Insert the plug into the SCP-84’s DC 3V jack.
4. Plug the adapter into the vehicle’s cigarette-lighter
socket.

Note: If the SCP-84 does not operate when you turn it
on, remove the DC adapter from your vehicle’s cigarette-
lighter socket and check the socket for debris. Also,
check the fuse in the adapter and your vehicle’s fuse
block.
SETTING THE CLOCK
1. Set RADIO STEREO/MONO/TAPE to TAPE. The dis-
play shows the currently set time.

SETTING THE 9KHZ/10KHZ SWITCH
The 9kHz/10kHz switch on the back of the cassette com-
partment door is preset to 10kHz.
In the 10kHz setting, the SCP-84 tunes frequencies in in-
crements of 10 kHz (AM) and 0.1 MHz (FM), which is
standard in the United States.
However, in Europe and some other parts of the world,
AM frequencies are broadcast in increments of 9 KHz. If
you use the SCP-84 in these countries, use a pointed ob-
ject, such as a straightened paper clip, to set 9kHz/10kHz
to 9kHz.

CONNECTING HEADPHONES OR
AMPLIFIED SPEAKERS
To listen to the SCP-84, you need a pair of headphones
or amplified speakers with a 1/8-inch plug. Your local Ra-
dioShack store carries a wide selection of headphones
and amplified speakers.
Insert the headphones’ or speakers’ 1/8-inch plug into the
SCP-84’s PHONES 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.
• Do not listen at extremely high volume levels.
Extended high-volume listening can lead to perma-
nent hearing loss.
• Once you set the volume, do not increase it. Over
time, your ears adapt to the volume level, so a vol-
ume 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 let you hear some out-
side sounds when listening at normal volume levels, they
still can present a traffic hazard.

USING THE RADIO
LISTENING TO THE RADIO
Important: Make sure you have connected headphones
or speakers to the SCP-84. See “Connecting Head-
phones or Amplified Speakers” on Page 15.

reo sound on FM stations. STEREO appears when
you receive an FM broadcast in stereo. Set RADIO
STEREO/MONO/TAPE to MONO for monaural recep-
tion.

Notes:
• The SCP-84 has a built-in AM antenna, and the
headphones’ or speakers’ cord serves as an FM
antenna. For the best AM reception, rotate the
SCP-84. For the best FM reception, fully uncoil the
headphones’ or speakers’ cord.
• If FM stereo reception is poor or noisy, set RADIO
STEREO/MONO/TAPE to MONO. The sound is not in
stereo, but reception should improve.
5. Set E-BASS IN/OUT to IN for extra bass effect, or to
OUT to leave the bass sound unchanged.
6. To turn off the radio, set RADIO STEREO/MONO/TAPE
to TAPE.
