PREPARATION  
CONNECTING POWER  
Using Batteries  
You can power your recorder with two AA bat-  
teries (not supplied). For the best perfor-  
mance and longest life, we recommend  
RadioShack alkaline batteries.  
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-40. Batteries can leak chemicals  
that can destroy electronic circuits.  
• Do not mix old and new batteries, differ-  
ent types of batteries (standard, alkaline,  
or rechargeable), or rechargeable batter-  
ies 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.  
Notes:  
• If REC/BATT lights dimly during play-  
back 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 out-  
let 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 DC 3V  
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.

Listening Safely  
To protect your hearing, follow these guide-  
lines 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 the volume, do not increase  
it. Over time, your ears adapt to the vol-  
ume 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.  
• 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 record-  
MIC  
er’s  
jack. The built-in microphone auto-  
matically disconnects.

OPERATION  
LOADING A  
MICROCASSETTE TAPE  
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.  
1. Use a pencil to turn the cassette's hub  
and remove any tape slack. Avoid touch-  
ing the tape.  
2. Press STOP/EJECT. The cassette com-  
partment door opens.  
3. Insert the microcassette into the door's  
guides with the tape’s open edge facing

out and the full reel positioned toward the  
top of the recorder.  
4. Close the door.  
RECORDING  
Cautions:  
• Do not change the tape speed while  
recording.  
• Do not force down REC when a cassette  
erase-protection tab is not in place (see  
“Restoring Tape Tension and Sound  
Quality” on Page 22).  
Voice Activated (VOX) Recording  
Follow these steps to have the recorder start  
and stop recording automatically based on  
sound it detects.

1. Set VOX to ON.  
2. Load a tape.  
3. Set TAPE SPEED on the side of the  
recorder as follows:  
To double the tape’s recording/play-  
back time, set TAPE SPEED to 1.2. This  
setting allows 120 minutes of total  
recording/playback time on an MC-60  
tape, or 180 minutes on an MC-90  
tape.  
• For better sound quality, set TAPE  
SPEED to 2.4. This setting allows 60  
minutes of total recording/playback  
time on an MC-60 tape, or 90 minutes  
on an MC-90 tape.

4. Press REC to begin recording. Both REC  
and PLAY lock down, and the record/bat-  
tery indicator (to the right of the tape  
counter) lights.  
Notes:  
• The VOLUME setting determines the  
sound level that activates the VOX cir-  
cuit and starts recording. At higher  
settings, a softer sound starts VOX  
recording. At lower settings, a louder  
sound starts VOX recording.  
• The built-in automatic level control  
(ALC) automatically sets the recording  
level once recording starts.  
• When you use the VOX feature,  
recording begins when the recorder  
picks up sound and stops a few sec-  
onds after the sound stops.  
5. For maximum clarity, place the recorder  
as close to the sound source as possible,  
with nothing between the source and the  
recorder that might block the sound.  
6. To temporarily stop recording, slide  
PAUSE to ON. To resume recording, slide  
PAUSE back.  
7. Recording stops when the tape reaches  
the end of the cassette. To stop it sooner,  
press STOP/EJECT.

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: Be careful not to damage the micro-  
cassette when tapping it. Do not touch the ex-  
posed 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 cas-  
sette tape using a RadioShack bulk tape  
eraser.  
PREVENTING ACCIDENTAL  
ERASURE  
Microcassette tapes have two erase-pro-  
tection tabs — one for each side. When a  
tab is in place, you can record on that side.  
To prevent accidental erasure of a tape re-  
cording, use a screwdriver to remove one or  
both of the cassette tape’s erase protection  
23

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 af-  
ter 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

take it to your local RadioShack store for as-  
sistance.  
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-40. After every
