POWERING THE CD PLAYER

You can power your CD player from any of these sources:

  two AA alkaline batteries.

  two special rechargeable AA nickel-cadmium batteries.

  two standard rechargeable AA nickel-cadmium batteries.

  vehicle battery power using an optional DC adapter.

  standard AC power using an optional AC adapter.

Note:  Connecting an AC or DC adapter to the CD player when
       non-rechargeable batteries are installed disconnects the batteries.

USING BATTERIES

You can power the CD player from two AA alkaline batteries.  For the best
performance and longest life, we recommend alkaline batteries such as
RadioShack Cat. No. 23-557.  You can also use the following types of
rechargeable nickel-cadmium batteries to power the CD player:

  Two special AA rechargeable nickel-cadmium batteries (RSU No. 11672508,
  available, through your local RadioShack store).

    You can use an AC or DC adapter to recharge these batteries while they
    are installed in the battery compartment.

  Two standard AA rechargeable nickel-cadmium batteries (such as Cat. No.
  23-125).

    You cannot charge standard nickel-cadmium rechargeable batteries
    inside the CD player's battery compartment, but you can charge them
    using an external battery charger such as Cat. No. 23-133 (not
    supplied).

Note:  All types of nickel-cadmium batteries come fully discharged.  Be
       sure to fully charge the batteries before you use them the first
       time.

Installing Batteries

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

           Do not mix old and new batteries, different types of batteries
           (standard, alkaline, or rechargeable) or rechargeable batteries
           of different capacities.

Follow these steps to install the batteries.

1.  Slide the battery compartment cover in the direction of the arrow,
    then gently pull up on the cover to open it.

    CAUTION:  The battery compartment cover is attached to the CD player.
              Do not try to remove it.

2.  Place two AA batteries in the compartment and on top of the attached
    ribbon, as indicated by the polarity symbols (+ and -) marked inside.

3.  Close the cover.

When BATT flashes, the sound distorts, or the volume weakens, replace or
recharge the batteries.

CAUTIONS:  Dispose of old batteries promptly and properly.  Do not burn or
           bury them.

           Always remove or recharge old or weak batteries.  Batteries can
           leak chemicals that can destroy electronic parts.

           If you do not plan to use the CD player with batteries for a
           month or more, or if you plan to use only an AC or DC adapter,
           remove the batteries.  Batteries can leak chemicals that can
           destroy electronic parts.

Recharging Nickel-Cadmium Batteries

If you connect an AC or DC adapter to the CD player, you can set the CD
player to charge special nickel-cadmium batteries while they are inside
the battery compartment.

CAUTION:  Use only an AC adapter or DC adapter that meets the
          specifications in "Using AC Power", below, or "Using Vehicle
          Battery Power", below to recharge the batteries in the CD
          player.  Other adapters could damage your CD player or the
          batteries.

To charge special nickel-cadmium batteries in the CD player, simply
connect an AC or DC adapter to your CD player (see "Using AC Power", below
or "Using Vehicle Battery Power", below).  BATT CHARGE on the front of the
CD player lights while batteries are installed and charging.

When the batteries are fully charged, disconnect the AC or DC adapter.

Charging Tips/Facts

  It takes about 15 hours to charge new or fully discharged nickel-cadmium
  batteries (special or standard) in the CD player while it is not being
  used to play CDs.  Subsequent charges take 12-15 hours.

  You can play a CD while recharging the special nickel-cadmium batteries.
  However, this will cause the batteries to recharge more slowly.

  Under normal usage conditions, nickel-cadmium batteries can be recharged
  about 500 times.

  Fully discharge the batteries occasionally by playing the CD player
  until it no longer plays.  Then fully recharge the batteries.  This
  helps maintain the batteries' full charging capacity.

  IMPORTANT:  This CD player 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 curb-side collection, drop-off
              boxes at retailers such as your local RadioShack store,
              recycling collection centers, and mail-back programs.

Using AC Power

You can power the CD player from a standard AC outlet using an optional
AC adapter, such as Cat. No. 273-1664.

CAUTIONS:  You must use an AC adapter that supplies 4.5 volts and delivers
           at least 550 mA.  Its center tip must be set to positive and
           its plug must fit the CD player's 4.5V jack.  The recommended
           adapter meets these specifications.  Using an adapter that does
           not meet these specifications could damage the CD player or the
           adapter.

           Always plug the AC adapter into the CD player before you plug
           it into the AC outlet.  Always unplug the AC adapter from the
           AC outlet before you unplug it from the CD player.

Follow these steps to connect an AC adapter to the CD player.

1.  Plug the AC adapter's 5.5 mm outer diameter/2.1 mm inner diameter
    barrel plug into the cable so it reads + TIP.

2.  Set the AC adapter's voltage switch to 4.5V.

3.  Connect the AC adapter's barrel plug to the 4.5V jack on the back of
    the CD player.

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

CAUTION:  The CD player automatically disconnects battery power when you
          connect an AC adapter, unless you are using special rechargeable
          nickel-cadmium batteries.  Even though the CD player
          automatically does this, remove the special nickel-cadmium
          batteries to prevent overcharging if you plan to use the CD
          player with AC power for an extended period (8 hours or more).

Using Vehicle Battery

You can power your CD player from your vehicle's cigarette-lighter socket
using an optional 4.5 volt DC adapter, such as Cat. No. 273-1801.

CAUTIONS:  You must use a DC adapter that supplies 4.5 volts and delivers
           at least 550 mA of automotive power.  Its center tip must be
           set to positive and its plug must fit the CD player's 4.5V
           jack.  Using an adapter that does not meet these specifications
           could damage the CD player or the adapter.

           Always plug the DC adapter into the CD player before you plug
           it into the cigarette-lighter socket.  Always plug the DC
           adapter into the CD player before you plug it into the
           cigarette-lighter socket.  Always unplug the DC adapter from
           the cigarette-lighter socket before you unplug it from the CD
           player.

Follow these steps to connect a DC adapter to the CD player.

1.  Plug the DC adapter's 5.5 mm outer diameter/2.1 mm inner diameter
    barrel plug into the cable so it reads + TIP.

2.  Set the DC adapter's voltage switch to 4.5 volts.

3.  Connect the DC adapter's barrel plug to the 4.5V jack on the back of
    the CD player.

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

Note:  If the CD player does not operate when you use the DC adapter,
       unplug the cord from the cigarette-lighter socket and clean any
       ashes or debris from the socket.
