Micro-22  (140-1160)          Power Sources            Faxback Doc. # 7999

You can power your Micro-22 from any of the following:

           Internal battery power

           AC power (with an AC adapter)

           a vehicle's battery (with a DC adapter)

USING BATTERIES

You can use two AA batteries, such as Radio Shack Cat. No. 23-552, to
power your Micro-22.  Or, you can use rechargeable nickel-cadmium
batteries (Cat. No. 23-125) with a battery charger (Cat. No. 23-133).

Cautions:  Use only fresh batteries of the required size and type.

           Never leave dead or weak batteries in the Micro-22.

           Do not mix non-rechargeable batteries with rechargeable
           batteries, or rechargeable batteries of different capacities.

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

Follow these steps to install the batteries.

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

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

3.  Replace the battery compartment cover.

    Note:  If you do not plan to use the Micro-22 for several days, remove
           the batteries.

    Important:  Your recorder 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
                mail-back programs.

USING AC POWER

To power the Micro-22 from an AC outlet, you need an AC adapter
(not supplied), such as Cat. No. 273-1662.

Cautions:  You must use an AC adapter that supplies 3 volts DC power
           and delivers at least 200 milliamps.  Its center tip must
           be set to negative, and its plug must properly fit the
           Micro-22's DC 3V jack.  The recommended adapter meets these
           specifications.  Using an adapter that does not meet these
           specifications could damage the Micro-22 or the adapter.

           Always connect the AC adapter to the Micro-22 before you
           plug it into the AC outlet, and unplug the adapter from the
           AC outlet before you unplug it from the Micro-22.
           the AC outlet before you unplug it from the Micro-22.

Follow these steps to power the Micro-22 from standard AC power.

1.  Set the AC adapter's voltage switch to 3V.

2.  Attach the green-rimmed barrel plug to the AC adapter's cord with the
    tip set to negative (-).

Caution:   Be sure to set the tip polarity to negative (-).  If the
           polarity is reversed, the recorder, tape, or AC adapter might
           be damaged.

3.  Insert the AC adapter's battery plug into the recorder's DC 3V jack.
    This disconnects the internal batteries.

4.  Plug the other end of the AC adapter into a standard AC outlet.

USING VEHICLE BATTERY POWER

To power the Micro-22 from your vehicle's battery, you need a DC adapter,
such as Cat. No. 270-1560.

Cautions:  Your vehicle must have a 12-volt, negative-ground electrical
           system.

           You must use a DC adapter that supplies 3 volts DC power and
           delivers at least 200 milliamps.  Its center tip must be set to
           negative, and its plug must properly fit the Micro-22's DC 3V
           jack.  The recommended adapter meets these specifications.
           Using an adapter that does not meet these specifications could
           damage the Micro-22 or the adapter.

           Always plug the adapter into the Micro-22 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-22.

Follow these steps to power the Micro-22 from your vehicle's battery.

1.  Set the DC adapter's voltage switch to 3V.

2.  Plug the blue-rimmed barrel plug into the DC adapter's cord with the
    tip set to negative (-).

Caution:   Be sure to set the tip polarity to negative (-).  If the
           polarity is reversed, the recorder, tape, or DC adapter
           might be damaged.

3.  Insert the DC adapter's barrel plug into the Micro-22's DC 3V jack.
    This disconnects the internal batteries.

4.  Plug the other end of the DC adapter into the vehicle's cigarette-
    lighter socket.
