Powering the CD Player

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

  Two AA alkaline batteries (not supplied).

  Two rechargeable AA nickel-cadmium batteries (not supplied)

  Standard AC power using an AC adapter (not supplied).

  Vehicle battery power using a CD adapter (not supplied).

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

Using Batteries

You can power your CD player from two AA alkaline batteries or two AA 
rechargeable nickel-cadmium batteries.  Both types of batteries are 
available at your local RadioShack store.

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

2.  Place two AA batteries in the compartment as indicated by the polarity
    symbols (+ and -) marked inside.

3.  Replace the cover.

When (battery symbol) flashes or the CD player stops operating properly, 
replace the batteries.

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

CAUTION:  If you do not plan to use the CD player for a month or more,
          remove the batteries.  Batteries can leak chemicals that can
          destroy electronic parts.

Charging Rechargeable Batteries

This CD player can fully charge the recommended rechargeable nickel
cadmium batteries in about 17 hours.  You can play a CD while charging the 
nickel-cadmium batteries; however, this will cause the batteries to charge 
more slowly.

Follow these steps to charge rechargeable batteries.

1.  Connect and optional AC or DC adapter to the CD player's DC IN 4.5V
    jack (see "Using AC Power" or "Using Vehicle Battery Power" below).

2.  After 17 hours, unplug the adapter then disconnect it from the CD
    player's DC IN 4.5V jack.

CAUTION:  Do not overcharge the batteries.  Overcharging can significantly
          reduce the batteries' useful life.

IMPORTANT: This CD player can use nickel-cadmium rechargeable batteries.
           At the end of a nickel-cadmium battery's useful life, it 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 such as your local RadioShack store
           recycling collection centers, and mail-back programs.

Using AC Power

You can power the CD player using a 4.5 volt, 600 mA adapter and a size B 
Adaptaplug adapter (neither supplied).  Both adapters are available at 
your local RadioShack store.

CAUTIONS:  You must use a Class 2 adapter that supplies 4.5 volts DC and
           delivers at least 600 mA.  Its center must be set to positive
           and its plug must fit the CD player's DC IN 4.5V jack.  Using
           an adapter that does not meet these specifications could damage
           the CD player or the adapter.

           Always connect the AC adapter to the CD player before you
           connect it to AC power. When you finish, disconnect the adapter
           from AC power before you disconnect it from the CD player.

Follow these steps to connect the CD player to AC power.

1.  Insert the recommended Adaptaplug adapter into the AC adapter's cord,
    setting TIP to + (positive).

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

3.  Insert the AC adapter's barrel plug into the CD player's DC IN 4.5V
    jack.

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

5.  When you finish using the AC adapter, disconnect it from the AC outlet
    first, then unplug it from the CD player.

Note:  Always unplug the AC adapter before using the CD player with
       alkaline batteries.  Otherwise, the player will not operate.

Making the Connections

You can listen to your CD player by connecting earphones, headphones, or 
amplified speakers to the player's PHONES jack, or by connecting a home 
audio or autosound system to the CD player's LINE OUT jack.

Notes: If the jacks on your equipment do not match the plugs on the
       supplied Y-cable, check with your local RadioShack store for
       the proper cable adapter.

       If you use amplified speakers, connect them to the PHONES jack,
       not LINE OUT. Otherwise, FM radio reception might be weak or noisy.

Connecting Earphones or Headphones

For private listening, you can plug a pair of stereo earphones or 
headphones (not supplied) with a 1/8 inch (3.5 mm) plug into the PHONES 
jack on the CD player.

Listening Safely

To protect your hearing, follow these guidelines when you use earphones or 
headphones.

  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 earphone or headphones 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 and headphones let you hear some outside sounds 
when listening at normal volume levels, they still can present a traffic 
hazard.
