FEATURES
Your Optimus Micro-39 Microcassette Record-
er 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 you
note specific points in a tape for later reference.
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 ratio with low distortion.
Three Power Options — you can power the
recorder from standard AC power using an op-
tional AC adapter, two AA batteries (not sup-
plied), 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 bat-
teries (not supplied) or rechargeable AA Ni-Cd
batteries (not supplied). For the best perfor-
mance and longest life, we recommend Ra-
dioShack alkaline batteries. (Both Ni-Cd
batteries and the correct battery charger are
available at your local RadioShack store.)
Warning: Dispose of old batteries promptly; do
not bury or burn them.
Cautions:
• Use only fresh batteries of the required
size and recommended type.
• Never leave dead or weak batteries in the
Micro-39. Batteries can leak 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 plan to use the Micro-39 for
several days, or if you plan to use only AC or
vehicle battery power, remove the batteries.

Using AC Power
You can power the Micro-39 using an 3V, 300-
mA AC adapter and a size H Adaptaplug®(nei-
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 cen-
ter tip must be set to negative and its plug
must fit the Micro-39's DC 3V jack. Using
an adapter that does not meet these speci-
fications 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 discon-
nect it from the Micro-39.
Follow these steps to power the Micro-39 from
standard AC power.

1. Set the AC adapter's voltage switch to 3V if
it is equipped with a voltage selection
switch.
2. Insert the AC adapter’s Adaptaplug into the
AC adapter's cord so it reads TIP–.
3. Insert the adapter’s barrel plug into DC 3V
on the recorder.
Note: Inserting the barrel plug into the
Micro-39's DC 3V jack disconnects the
internal batteries.
4. Plug the adapter’s other end into a stan-
dard AC outlet.
Using Vehicle 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 local RadioShack store.

Cautions:
You must use a 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 DC 3V jack. Using an adapter
that does not meet these specifications
could damage the Micro-39 or the adapter.
• Always connect the DC adapter to the Mi-
cro-39 before you connect it to the power
source. When you finish, disconnect the
adapter from the power source before you
disconnect it from the Micro-39.
Follow these steps to power the Micro-39 from
your vehicle's battery.
1. Set the DC adapter's voltage switch to 3V.
2. Insert the AC adapter’s Adaptaplug into the
adapter's cord so it reads TIP–.

3. Insert the barrel plug into the Micro-39's DC
3V jack.
Note: Inserting the barrel plug into the
Micro-39's DC 3V jack disconnects the
internal batteries.
4. Plug the other end of the DC adapter into
the vehicle's cigarette-lighter socket.
CONNECTING AN EARPHONE
You can use an optional mono earphone with a
1/8-inch (3.5-mm) plug to listen privately 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 ear-
piece.
• Your local RadioShack store carries a wide
selection of earphones.
