FEATURES

Your Optimus Micro-37 Voice-Activated

Microcassette Tape Recorder is ideal for quick note-taking. Its ultra-small size makes it easy to slip into a pocket or briefcase. You can use it at school, at business conferences, for dictation in the office, or anywhere on the go! You can start recording manually or set the recorder so sound activates recording.

Your recorder includes these features:

Voice-Activation Circuitry (VOX) — begins recording when the recorder picks up sound and stops a few seconds after the sound stops.

Tape Counter with Reset Button — lets you mark the locations of certain sections of tape so you can easily return to them.

Built-In Microphone and Speaker — let you record and play back notes anywhere.

PREPARATION

BEFORE YOU BEGIN

To protect the Micro-37 during shipment, a piece of paper is attached to the cassette door. Remove this paper before you use the Micro-37.

CONNECTING TO POWER

You can power your Micro-37 from any of the following:

• Internal battery power

• AC power (with an optional AC adapter)

• Your vehicle’s battery (with an optional

DC adapter)

14-1164.fm Page 7 Wednesday, November 25, 1998 1:20 PM

Using Batteries

You can use two AA batteries (not supplied) to power your Micro-37. We recommend alkaline batteries, such as RadioShack Cat. No. 23-552.

Cautions:

• Use only fresh batteries of the required size and recommended type.

• Never leave dead or weak batteries in the Micro-37. 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.

• Dispose of old batteries promptly; do not bury or burn them.

7

14-1164.fm Page 8 Wednesday, November 25, 1998 1:20 PM

Follow these steps to install batteries.

1. Slide the battery compartment cover in the direction of the arrow until it stops, then lift up the cover.

Caution: The battery compartment cover is attached to the recorder. Do not try to remove it.

2. Insert the batteries into the compartment as indicated by the polarity symbols (+ and –) marked inside the compartment.

8

3. Close the battery compartment cover by pressing it down and sliding it in the opposite direction of the arrow.

14-1164.fm Page 9 Wednesday, November 25, 1998 1:20 PM

Notes:

• If the record/battery indicator to the right of the

EAR

jack does not light or lights dimly during manual recording, replace the batteries.

• If you do not plan to use the Micro-37 for several days, or if you plan to use only AC or vehicle battery power, remove the batteries.

9

14-1164.fm Page 10 Wednesday, November 25, 1998 1:20 PM

Using AC Power

To power the Micro-37 from an AC outlet, you need an AC adapter (not supplied), such as Cat. No. 273-1654B.

Cautions:

• You must use an AC adapter that supplies 3 volts DC power and delivers at least 200 milliamps. The center tip of the adapter barrel plug must be set to positive, and the plug must properly fit the Micro-37’s

DC3V

jack. The recommended AC adapter meets these specifications. Using an AC adapter that does not meet these specifications could damage the Micro-37, the

AC adapter, or the plug.

• Always connect the AC adapter to the

Micro-37 before you plug it into the AC outlet, and unplug the adapter from the AC outlet before you unplug it from the Micro-37.

Using Vehicle Battery Power

To power the Micro-37 from your vehicle’s battery, you need a DC adapter (not supplied), such as Cat. No. 270-1560.

Cautions:

• You must use a DC adapter that supplies 3 volts DC power and delivers at least 200 milliamps. The center tip of its barrel plug must be set to positive, and the plug must properly fit the

Micro-37’s

DC3V

jack. The recommended DC adapter meets these specifications. Using a DC adapter that does not meet these specifications could damage the Micro-37 or the DC adapter.

• Always plug the DC adapter into the

Micro-37 before you plug it into the cigarette-lighter socket, and unplug the adapter from the cigarette-lighter socket before you unplug it from the

Micro-37.

32

-inch) plug to listen to a tape in privacy.

Notes:

• You can also use an earphone to monitor what the recorder picks up through the internal microphone or an external microphone.

• Your local RadioShack store carries a wide selection of earphones.

Insert the earphone’s plug into the recorder’s

EAR

jack. The built-in speaker automatically disconnects.

14-1164.fm Page 15 Wednesday, November 25, 1998 1:20 PM

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 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.

Even though some earphones let you hear outside sounds when listening at normal volume levels, they still can present a traffic hazard.

TAPE TIPS

STORING CASSETTE

TAPES

Do not expose microcassette tapes to high temperatures, high humidity, dust or dirt, or motors, transformers, or other sources with strong magnetic fields.

PREVENTING ACCIDENTAL

ERASURE

Most microcassette tapes have an eraseprotection tab for each side of the tape. To protect your recordings from being accidentally erased or recorded over, use a screwdriver to carefully break off the eraseprotection tabs.

Side A Tab

If you later decide to erase or record over the tape, place a piece of strong tape over the holes.

27

14-1164.fm Page 28 Wednesday, November 25, 1998 1:20 PM

Caution: Removing the erase-protection tabs does not prevent a tape from being erased by a bulk tape eraser.

ERASING A CASSETTE

TAPE

If you no longer want a recording, you can record over it or erase it.

To record over a microcassette tape, be sure the erase-protection tabs are in place.

Then simply record as usual. The recorder records over the previous recording.

You might prefer to use a bulk tape eraser, such as Cat. No. 44-232, which erases both sides of a tape in just a few seconds.

28

14-1164.fm Page 29 Wednesday, November 25, 1998 1:20 PM

CARE

Your Optimus Micro-37 Voice-Activated

Microcassette Tape Recorder is an example of superior design and craftsmanship.

The following suggestions will help you care for your recorder so you can enjoy it for years.

• Keep the recorder dry. If it gets wet, wipe it dry immediately. Liquids can contain minerals that can corrode the electronic circuits.

• Handle the recorder gently and carefully. Dropping it can damage circuit boards and cases and can cause the recorder to work improperly.

• Use and store the recorder only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, damage batteries, and distort or melt plastic parts.

• Keep the recorder away from dust and dirt, which can cause premature wear of parts.

• Wipe the recorder with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean it.

29

14-1164.fm Page 30 Wednesday, November 25, 1998 1:20 PM

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.

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 recorder. Use the following cleaning procedure after every 20 hours of recorder operation.

STOP

, remove the batteries, and disconnect any other power source.

2. Press

PLAY

to expose the tape-handling parts.

30

14-1164.fm Page 31 Wednesday, November 25, 1998 1:20 PM
