FEATURES
Your Optimus Micro-39 Microcassette Recorder is ideal for quick note-taking. The recorder’s
handstrap and its ultra-small size makes it easy
to slip into a pocket, briefcase, or purse. You
can use it at school, at business conferences,
for dictation in the office, or anywhere you are
on the go! You can record manually or set the
recorder so sound activates recording.
Your recorder includes these features:
Voice-Activated Recording (VOX)
— lets you
set the Micro-39 so it records when it picks up
sound and stops a few seconds after the sound
stops.
Auto Stop
— stops the tape when the recorder
reaches the end of the tape during recording,
playback, fast forward, or rewind.
Tape Counter with Reset Button
— lets yo u
note specific points in a tape for l ate r r efere nc e.
Tape Speed Switch
— lets you record and
play back tape at twice the normal recording/
playback time (at a slower speed) or at normal
speed (for maximum sound quality).

Cue/Review
— lets you hear a recording as
you fast-forward or rewind a tape so you can
quickly locate a specific passage on the tape.
Built-In Microphone and Speaker
— let you
record and play back notes anywhere.
External Microphone Jack
— lets you use an
external, wide range microphone.
Fast Play
— lets you play a tape about 30%
faster than normal so you can hear the entire
tape quickly or reach certain passages faster.
Automatic Level Control (ALC) Circuit
— au-
tomatically sets the recording level.
AC Bias Circuit
— ensures a high signal-to-
noise rati o with low distortion.
Three Power Options
— you can power the
recorder from standard AC power using an optional AC adapter, two AA batteries (not supplied), or a vehicle’s battery using an optional
DC adapter.
We recommend you write your recorder’s serial
number here. The number is inside the battery
compartment.

PREPARATION
CONNECTING POWER
Using Batteries
You can power your Micro-39 with two AA batteries (not supplied) or rechargeable AA Ni-Cd
batteries (not supplied). For the best performance and longest life, we recommend RadioShack alkaline batteries. (Both Ni-Cd
batteries and the correct battery charger are
available at your loc al RadioShack store.)
Warning:
not bury or burn them.
Cautions
Dispose of old batteries promptly; do
:
• Use only fresh batteries of the required
size and recommended type.
• Never leave dead or weak batteries in the
Micro-39. Batteries c an le ak chemicals that
can destroy electronic circuits.
• Do not mix old and new batteries, different
types of batteries (standard, alkaline, or
rechargeable), or rechargeable batteries of
different capacities.

1. Slide the battery compartment cover in the
direction of the arrow.
2. Insert the batteries into the compartment
as indicated by the polarity symbols (+ and
–) marked inside.
3. Replace the cover.
If RECORD/BATT lights dimly during recording,
or it does not light at all, replace the batteries.
Note:
If you do not pl an to u se t h e Mi cr o -39 f o r
several days, or if you plan to use only AC or
vehicle battery power, remove the batteries.

14-1167.fm Page 7 Thursday, January 20, 2000 2:02 PM
Using AC Power
You can power the Micro-39 using an 3V, 300mA AC adapter and a size H Adaptaplug
ther supplied). Both are available at your local
RadioShack store.
Cautions:
You must use a Class 2 power
source that supplies 3V DC and
!
delivers at least 300 mA. Its center tip must be set to negative and its plug
must fit the Micro-39's
an adapter that does not meet these specifications could damage the Micro-39 or the
adapter.
• Always connect the AC adapter to the
Micro-39 before you connect it to AC
power. When you finish, disconnect the
adapter from AC power before you disconnect it from the Micro-39.

4. Plug the adapter’s other end into a standard AC outlet.
Using Ve hicle Battery Power
You can power the Micro-39 from a vehicle’s
12V power source (such as cigarette-lighter
socket) using a 3V, 300-mA DC adapter and a
size H Adaptaplug (neither supplied). Both are
available at your loc al RadioShack store.

CONNECTING AN EARPHONE
You can use an optional mono earphone with a
1
/8-inch (3.5- mm) plug to listen priva tely to the
Micro-39.
Notes:
• You can also use an earphone to monitor
what the recorder picks up through the
internal or an external microphone.
• While you can connect stereo earphones,
they produce sound only from the left earpiece.
• Your local RadioShack store carries a wide
selection of earphones .

14-1167.fm Page 11 Thursday, January 20, 2000 2:02 PM
Insert the earphone's plug into the recorder's
EAR
jack. The internal speaker automatically
disconnects
.
Listening Safely
To protect your hearing, follow these guidelines
when you use an earphone.
• Set the volume to the lowest setting before
you begin listening. After you begin listening, adjust the volume to a comfortable listening level.
• Do not listen at extremely high volume lev-
els. Extended high-volume listening can
lead to permanent hearing loss.
• Once you set the volume, do not increase
it. Over time, your ears ada pt to the volum e
level, so a volume level that does not
cause discomfort might still damage your
hearing.
11
Page 12
14-1167.fm Page 12 Thursday, January 20, 2000 2:02 PM
Traffic Safety
• Do not wear an e arph one w h ile o pe r atin g a
motor vehicle or riding a bicycle. This can
create a traffic hazard and could be illegal
in some areas.
• Even though some earphones let you hear
outside sounds when listening at normal
volume levels, they still can present a traffic hazard.
CONNECTING AN EXTERNAL
MICROPHONE
You can use an optional microphone with an
1
/8-inch (3.5-mm) plug to extend the recording
range. Your local RadioShack store carries a
wide selection of microphones.
Insert the microphone’s plug into the recorder’s
MIC
jack. The built-in microphone automatically
disconnects.

Note:
We recommend MC-60 microcassette
tapes for up to 2 hours of recording/playback
time, or MC-90 microcassette tapes for up to 3
hours of recording/playback time. We do not
recommend long-playing microcassette tapes
such as MC-120s, because they are extremely
thin and can easily tangle in the playback
mechanism.

TAPE TIPS
STORING CASSETTE TAPES
Do not expose mic rocas sette tapes to hig h temperatures, high humid ity, dust or dirt, or moto rs,
transformers, or other sources of strong magnetic fields.
RESTORING TAPE TENSION
AND SOUND QUALITY
After you play a microcassette tape several
times, the tape might become tightly wound on
the reels. This can ca us e pl ay bac k s ou nd q ual ity 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:
cassette when tapping it. Do not touch the exposed tape or allow any sharp objects near the
cassette.

ERASING TAPES
To record over a microcassette tape, simply
record as usual. The tap e record er records over
the previous recording.
You can quickly erase both sides of a cassette
tape using a RadioShack bulk tape eraser.
PREVENTING ACCIDENTAL
ERASURE
Microcassette tapes have two erase-protection
tabs — one for each side. When a tab is in
place, you can record on that side.
To prevent accidental erasure of a tape recording, use a screwdriver to remove one or
both of the cassette tape’s erase protection
tabs. This prevents

14-1167.fm Page 24 Thursday, January 20, 2000 2:02 PM
If you later decide to record on a tape side after
you have removed the erase-protection tab,
place a piece of strong plastic tape over that
side’s erase- pr otect ion hole. Be sur e you cover
only the hole originally covered by the eraseprotection tab.
Caution:
Removing the erase-protection tabs
does not prevent a bulk eraser from erasing a
microcassette tape.

CARE
To enjoy your Optimus Micro-39 Microcassette
Recorder for a long time:
• Keep the recorder dry. If it gets wet, wipe it
dry immediately.
• Handle the recorder gently and carefully.
Don’t drop it.
• Use and store the recorder only in normal
temperature environm ent s.
• Keep the recorder away from dust and dirt.
• Wipe the recorder with a damp cloth occasionally to keep it looking new.
Modifying or tamperi ng with t he re corder's internal components can cause a malfunction and
might invalidate the recorder's warranty. If your
recorder is not operating as it should, take it to
your local Ra dioShack sto re for assistance.
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 Micro-39. After every 20
hours of tape player operation, follow these
steps to clean the tape-handling parts or use a
RadioShack microcassette deck cleaning kit.
