Micro-17  (140-1178)             Installation          Faxback Doc. # 9841

SUPPLYING POWER

You can power your Micro-17 from any of three power sources:

    internal batteries

    standard AC power (with an optional AC adapter)

Using Internal Batteries

You can use two AA batteries to power your Micro-17.  We recommend
alkaline batteries, such as Radio Shack Cat. No. 23-557.  You can also use
rechargeable nickel-cadmium batteries (Cat. No. 23-125) with a battery
charger (Cat. No. 23-234).

Caution:  Do not mix non-rechargeable and rechargeable batteries in the
          Micro-17.

Follow these steps to install the batteries.

1.  Press down on the battery compartment cover and slide it in the
    direction of the arrow to remove it.

2.  Install the batteries as indicated by the polarity symbols (+ and -)
    marked inside the battery compartment.

Notes:  Fresh alkaline batteries last for about 18 hours.  If the volume
        sounds weak or if the Micro-17 does not work properly, replace the
        batteries.

        Use only fresh batteries of the required size and type.

        Do not mix old and new batteries.

3.  Replace the cover.

Cautions:  Never leave dead or weak batteries in the Micro-17.

           If you do not plan to use the Micro-17 for a month or more,
           remove the batteries.

           Dispose of batteries properly; do not bury or burn them.

Note:  The Micro-17 is capable of using rechargeable nickel-cadmium
       batteries.  At the end of the batteries' useful life, they must be
       recycled or disposed of properly.  Contact your local, county, or
       state hazardous waste management authorities for information on
       recycling or disposal programs in your area.  Some options that
       might be available are:  municipal curbside collection, drop-off
       boxes at retailers, recycling collection centers, and mailback
       programs.

Using AC Power

To power the Micro-17 from an AC outlet, you need an AC adapter such as
Cat. No. 273-1654.

Cautions:  You must use an AC adapter that supplies 3 volts and delivers
           at least 200 milliamps.  Its center tip must be set to
           negative, and its plug must correctly fit the Micro-17's DC 3V
           jack.  Using an adapter that does not meet these specifications
           could seriously damage the Micro-17 or the adapter.

           Always unplug the AC adapter from the AC outlet before you
           unplug its barrel plug from the Micro-17.

Insert the AC adapter's barrel plug into the DC 3V jack on the side of the
Micro-17, then plug the AC adapter into a standard AC outlet.

Note:  the internal batteries automatically disconnect when you connect an
       AC adapter.

Using a Vehicle's Cigarette-Lighter Socket

To power the Micro-17 from a vehicle's cigarette-lighter socket, you need
a DC adapter such as Cat. No. 270-1560.

Cautions:  Your vehicle must have a 12-volt, negative-ground electrical
           system.  Most vehicles have this type of system.  If you are
           not sure about your vehicle, check with your vehicle's dealer.

           You must use a DC cigarette-lighter adapter that supplies 3
           volts and delivers at least 200 milliamps.  Its center tip must
           be set to negative, and its plug must correctly fit the Micro-
           17's DC 3V jack.  Using an adapter that does not meet these
           specifications could seriously damage the Micro-17 or the
           adapter.

           Always unplug the adapter from your vehicle's cigarette-lighter
           socket before you unplug its barrel plug from the Micro-17.

1.  Connect the adapter's orange barrel plug to the adapter's cord,
    matching TIP to negative (-).

2.  Set the adapter's voltage switch to 3 volts.

3.  Insert the adapter's barrel plug into the Micro-17's DC 3V jack.

4.  Plug the adapter into the vehicle's cigarette-lighter socket.

Notes:  The internal batteries automatically disconnect when you connect a
        DC adapter.

        Unplug the adapter from your vehicle's cigarette-lighter socket
        when you turn off the ignition.  This prevents vehicle battery
        drain if you leave the Micro-17 on when you turn off the ignition.

CONNECTING THE EARPHONE

To connect the supplied earphone for private listening, insert the
earphone's 1/8-inch plug into the Micro-17's EAR jack.

Note:  When you connect the earphone, the Micro-17's 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 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 is illegal in some areas.

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

CONNECTING AN EXTERNAL MICROPHONE

The Micro-17 has a built-in microphone, but you can connect an optional
external microphone (such as Cat. No. 33-1067) if you want to move the
microphone closer to the sound source, or for other special recording
situations. Insert the microphone's 1/8-inch plug into the Micro-17's
MIC jack.

Note:  When you connect an external microphone the Micro-17's built-in
       microphone automatically disconnects.
