CONNECTING TO POWER

You can power your Micro-28 from any of the following:

    Internal batteries

    AC power (with an AC adapter)

    Your vehicle's battery (with a DC adapter)

Using Batteries

You can use two AA alkaline batteries, such as Radio Shack Cat. No. 23-552,
to power your Micro-28.  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-28.

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

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

NOTES:  If REC/BATT does not light or lights dimly during manual recording,
        replace or recharge the batteries.  Follow the instructions
        supplied with the battery charger to recharge the batteries.

        If you do not plan to use the Micro-28 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 mailback programs.

Using AC Power

To power the Micro-28 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 DC power and
           delivers at least 200 milliamps.  Its center tip must be set to
           negative, and it must have a plug that properly fits the Micro-
           28's DC 3V jack.  The recommended adapter meets these
           specifications.  Using an adapter that does not meet these
           specifications could damage the Micro-28 or the adapter.

           Always connect the AC adapter to the Micro-28 before you plug it
           into the AC outlet, and unplug the adapter from the AC outlet
           before you unplug it from the Micro-28.

Follow these steps to power the Micro-28 from standard AC power.

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

2.  Attach the black-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 or AC adapter might be damaged.

3.  Insert the AC adapter's barrel plug into the Micro-28's DC 3V jack.  
    This disconnects the internal batteries.

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