CONNECTING POWER
Using Battery Power
You can power your recorder from any
of these power sources:
You can power the recorder with four C
batteries (not supplied). For the longest
life, we recommend RadioShack alkaline batteries.
• standard AC power (using the supplied AC power cord)
Cautions:
• four C batteries (not supplied)
• vehicle battery power (with an
optional DC adapter)
Note: Connecting the supplied AC power cord or an adapter automatically disconnects internal batteries.
Using AC Power
To power the recorder from an AC outlet, connect the supplied AC power cord
to the recorder’s AC POWER jack. Then
plug the other end into a standard AC
outlet.
• Use only fresh batteries of the
required size and recommended
type.
• 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 by
pushing on the compartment cover’s
tabs and lifting the cover.
Caution: Plug the supplied power cord
into the recorder before you plug it into
the AC outlet, and unplug the power
cord from the AC outlet before you unplug it from the recorder.
2. Install the batteries according to the
polarity symbols (+ and –) marked on
the battery compartment door.
3. Replace the cover.
Preparation
3
When the RECORD/BATTERY indicator
lights during play or the sound becomes
weak or distorted, or when the playing
speed slows, replace the batteries.
Warning: Always dispose of old batteries promptly and properly. Do not burn
or bury them.
Follow these steps to power the recorder from your vehicle’s battery.
1. Set the adapter’s 6V/9V switch to
6V and plug the adapter into the
recorder’s DC 6V jack.
Note: If you do not plan to use the recorder for a week or more, or if you plan
to power it using only the supplied power cord or an adapter, remove the batteries. Batteries can leak chemicals that
corrode or damage electronic circuits.
Using DC Power
You can power the recorder from your
vehicle’s cigarette-lighter socket using a
fused DC adapter, available at your local
RadioShack store.
2. Insert the adapter’s other end into
your
vehicle’s
cigarette-lighter
socket.
Cautions:
You must use a power
source that supplies 6 volts
DC and delivers at least
400 mA. Its center tip must be set to
negative and its plug must fit the
recorder's DC 6V jack. The recommended adapter meets these specifications. Using an adapter that
does not meet these specifications
could damage the recorder or the
adapter.
!
• Plug the adapter into the recorder
before you plug it into the cigarettelighter and unplug the adapter from
the cigarette-lighter socket before
you unplug it from the recorder.

CONNECTING AN
EARPHONE
You can use the supplied earphone to
listen privately to a prerecorded tape or
to monitor a recording. You can also
connect an external or pillow-type
speaker (not supplied) to this jack.
Note: Your local RadioShack store carries a wide variety of speakers.
Preparation
Insert the earphone or speaker’s 1/8-inch
(3.5-mm) plug into the recorder’s EAR
jack. This automatically disconnects the
internal speaker.
mm) plug to the recorder’s MIC jack.
Connecting an external microphone automatically disconnects the built-in microphone.
Listening Safely
To protect your hearing, follow these
guidelines when you use an earphone.
• Do not listen at extremely high volume levels. Extended high-volume
listening can lead to permanent
hearing loss
• Set the volume to the lowest setting
before you begin listening. After you
begin listening, adjust the volume to
a comfortable level.
• 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 an earphone while operating a motor vehicle or riding a bicycle.
This can create a traffic hazard and
could be illegal in some areas.
Note: Your local RadioShack store carries a variety of microphones.
If you are using a microphone with a remote switch, insert the microphone’s
sub-mini plug into the cassette deck’s
REMOTE jack. You can use the microphone’s remote switch to start and stop
the cassette deck during play and recording.
CONNECTING AN
EXTERNAL AUDIO
SOURCE
You can use your recorder to record
from an external audio source, such as
a radio, cassette deck, or CD player.
Even though some earphones let you
hear some outside sounds when listening at normal volume levels, they still
can present a traffic hazard.
CONNECTING AN
EXTERNAL MICROPHONE
You can connect an external microphone (not supplied) with a 1/8-inch (3.5-
Disconnect any external microphone
from the recorder (an external microphone disables input to the AUX jack).
Preparation
5
Use an 1/8-inch (3.5 mm) patch cord to
connect the recorder’s AUX jack to the
audio source’s audio output jack.
! Operation
You can use your recorder to make recordings or to play your favorite cassette
tapes.

REVIEW/REWIND. This feature allows
you to quickly locate any desired section
You can record to a cassette tape on the
recorder from the built-in microphone,
an external microphone, or an external
audio source.
For the best performance, use regular
length (60-minute or 90-minute) cassette tapes. We do not recommend 120minute cassette tapes because they are
thin and can tangle easily. For lownoise, wide-range recordings, use only
normal-bias tapes.
Operation
7
Note: Be sure the erase-protection tabs
are in place on the cassette tape. See
“Preventing Accidental Erasure” on
Page 9.
If you set ALC to OUT, adjust VOLUME so the LEVEL METER lights to 0
dB during the loudest portions of the
sound signal.
Follow these steps to record.
1. Load a cassette tape into the cassette deck.
2. Set VOX to OUT if you want to manually start and stop recording. Or, set
VOX to HIGH or LOW, depending on
the sound source you want to
record.

audio source’s line level output jack,
set ALC to IN. The recorder will
automatically adjust the recording
level.
If you are recording from an external
audio source’s phones jack, turn on
the external audio source and set its
volume to a comfortable listening
level before you connect it to the
recorder (see “Connecting an External Audio Source” on Page 5). Then
use the recorder’s VOLUME control

Operation
Notes:
• To monitor what the recorder is
recording from an external audio
source, insert the supplied earphone’s plug into the EAR jack on
the recorder.
• To temporarily stop recording,
press PAUSE. To resume recording, press PAUSE again.
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.
Erasing Tapes
To record over a cassette tape, insert
the supplied dummy plug into the recorder’s MIC jack and record as usual.
The cassette deck records over the previous recording. To record over the entire cassette tape, let the tape record to
the end on both sides. When you finish,
remove the plug.
You can quickly erase both sides of a
cassette tape using a bulk tape eraser
(available at your local RadioShack
store).
6. If the cassette tape reaches its end,
the cassette deck automatically
releases RECORD and PLAY and
stops. To stop recording sooner,
press STOP/EJECT.
TAPE TIPS
Note: If you use metal or high-bias type
tape, the recorded sound might not be
erased properly.
Preventing Accidental Erasure
Cassette tapes have two erase-protection tabs — one for each side. When a
tab is in place, you can record on that
side.
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.
Operation
9
To prevent accidental erasure of a tape
recording, use a screwdriver to remove
one or both of the cassette tape’s eraseprotection tabs. This prevents RECORD
from being pressed.
If you later decide to record on a tape
side after you have removed the eraseprotection tab, place a piece of strong
plastic tape over that side’s erase-protection hole. Be sure you cover only the
hole originally covered by the erase-protection tab.
Caution: Removing the erase-protection tabs does not prevent a bulk eraser
from erasing a cassette tape.
! Care
Keep the recorder dry; if it gets wet,
wipe it dry immediately. Use and store
the recorder only in normal temperature
environments. Handle the recorder carefully; do not drop it. Keep the recorder
away from dust and dirt, and wipe it with
a damp cloth occasionally to keep it
looking new.

(available at your local RadioShack
store).
Modifying or tampering with the recorder’s internal components can cause a
malfunction and might invalidate its warranty. If your recorder is not performing
as it should, take it to your local RadioShack store for assistance.
CLEANING THE TAPEHANDLING 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 cassette player. After every 20
