FEATURES
Your Optimus Micro-40 Micro Cassette
Record with VOX is ideal for quick note-taking. Its ultra-small size makes it easy to slip

in the office, or anywhere on the go! You can
record manually or set the recorder so sound
activates recording.
Your recorder includes these features:
Voice-Activated Recording (VOX)
you set the Micro-40 so it records when it
picks up sound and stops a few seconds after
the sound stops.
— lets
Tape Speed Switch
— lets you re cord and
play back tape at a slower speed (which provides twice the recording/playback time) or at
normal speed (for maximum sound qual ity ) .
Auto Stop
— stops the tape when the recorder reaches the end of the tape during recording or playback.
Tape Counter with Reset Button
— lets you
note specific points in a tape for later reference.

PREPARATION
CONNECTING POWER
Using Batteries
You can power your recorder with two AA batteries (not supplied). For the best performance and longest life, we recommend
RadioShack alkaline batteries.
Warning:
do not bury or burn them.
Cautions
Dispose of old batteries promptly;
:
• Use only fresh batteries of the required
size and recommended type.
• Nev er leave dead or weak b atte ries i n the
Micro-40. Batteries can leak chemicals
that can destroy electronic circuits.
• Do not mix old and new batteries, different types of batteries (standard, alkaline,
or recharge able), or rech argeable b atteries 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 th e cover.
Notes:
•If
REC/BATT
lights dimly during playback or recording, or it does not light
at all, replace the batteries.
• If you do not plan to use the Micro-40
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-40 from an AC outlet using an AC adapter (not supplied), such
as RadioShack Cat. No. 273-1654.
Cautions:
You must use a Class 2 power
source that supplies 3 volts DC
and delivers at least 300 mA.
Its center tip must be set to positive and
its plug must fit the Micro-40's
jack. The recommended adapter meets
these specifications. Using an adapter
that does not meet these specifications
could damage the Micro-40 or the
adapter.
• Always plug the AC adapter in to the
Micro-40 before you plug it into the AC
outlet, and unplug the adapter from the
AC outlet before you unplug it from the
Micro-40.

Using Vehicle Battery Power
You can power the Micro-40 fro m a vehicle's
battery using a DC adapter (not supplied),
such as Cat. No. 273-1810.

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
levels. Extended high-volume listening
can lead to permanent hearing loss.
• Once you set th e v olu me , do not inc rease
it. Over time, your ears adapt to the volume level, so a volume level that does

not cause dis comfort might still d amage
your hearing.
Traffic Safety
• Do not wear an e arphone wh ile ope r ating
a motor vehicle or r iding a bicy cle. 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

TAPE TIPS
STORING CASSETTE TAPES
Do not expose microcassette tapes to high
temperatures, high humidity, dust or dirt, or
motors, 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 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:
cassette when tapping it. Do not touch the exposed tape or allow any sharp objects near
the cassette.

14-1168.fm Page 23 Thursday, January 20, 2000 2:05 PM
ERASING TAPES
To record over a microcassette tape, simply
record as usual. The tape recorder 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 accid ental erasure of a tape re cording, use a screwdriver to remove one or
both of the cassette tape’s erase protection
23
Page 24
14-1168.fm Page 24 Thursday, January 20, 2000 2:05 PM
tabs. This prevents
RECORD
from being
pressed.
Side A Tab
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-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
microcassette tape.

CARE
To enjoy your Your Optimus Micro-40 Micro
Cassette Recorder for a long time:
• Keep the reco rder dr y. 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 environments.
• Keep the recorder away from dust and
dirt.
• Wipe the recorder with a damp cloth
occasionally to keep it looking new.
Modifying or tampering with the recorder'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 RadioShack store for assistance.
