How to Insert the batteries into the battery compartment <Fig. 6>
Open the battery cover.
@ Lift the cover while pressing the STOP [ n 1 button
insert the batteries.
@ insert the four provided rechargeable batteries or alkali manganese batteries into the bat-
tery compartment surely by paying attention for correct polarity.
Close the battery cover.
@ Fit the hook of battery cover into the specified position.
@ Be sure to fit it into the specified position until it clicks and gets locked.
Charge the provided rechargeable batteries for 6 hours, if you use them for the
first time.
How to Recharge <Fig. 6>
Turn the Power off and insert provided rechargeable batteries into the battery compartment,
then connect an AC adaptor to the main unit before pressing CHARGE button in order to start
recharging. (Recharging cannot be conducted when Power is turned ON)
Recharging is canceled automatically by the built-in and 6-hour timer when recharging is com-
pleted.
1. If the STOP 1W1 and PLAY/PAUSE [ bill 1 button is pressed while recharging is being
conducted, POWER will be turned OFF. Recharging will be canceled when PLAY/PAUSE
[ WI 1 button is pressed during recharging. Other operations cannot be conducted.
2. The CHARGE button functions even though when the HOLD switch is turned ON.
3. Recharging is canceled when the AC-adaptor plug is pulled out an outlet while recharging
is being conducted, or when power supply is cut.
How to Recognize the Recharging Time
In the normal use, 5 hours of recharging allows continuous play for about 2 hours.
Recharge them for about 6 hours, however, if they are not used for a long period of time.
How to make batteries stand up to long use
If recharge is repeated for the provided batteries, whereas the power of batteries is still re-
mained, the batteries may not be recharged enough as their property. In such a case, use
up the power of them before conducting recharging, which allows them for normal recharging.
Cautions:
Do not recharge the manganese and alkali manganese batteries.
Be sure to use only the provided and AC adaptor for recharging. It is dangerous if you use
other kind of AC adaptor.
Avoid adverse recharging and short circuit. They result in causing of such troubles as deterio-
ration of rechargeable batteries and generation of heat.
Do not disassemble and modify it by yourself.
Do not touch the CD player and AC adaptor with wet hands
Should the liquid contained in the battery attach on your skin or clothes due to breakage, etc.
rinse it off with much running water.
Avoid overcharging a battery for 24 hours or more. It shortens the battery life.

Listening through headphones <Fig. 7>
l Connect the headphone (optional) plug with the “PHONES” jack fuse 43.5 stereo mini plug).
Conduct the pull-in/out operation of the jack during Power is OFF_.
l Adjust the volume with the VOLUME control.
Notes:
l Keep the plug of headphone clean all the time.
Non-clean plug may cause noise.
0 Avoid using the headphone when you drive a car and so on for traffic safety
0 Be careful not to fall asleep with the headphone on.
As a Compact Disc contains very little noise, a sudden loud sound could be output
if the VOLUME control is adjusted too high: this could cause serious damage to
your ears.
Playback through a home audio system
q Playback using the “LINE OUT” output <Fig. 8>
l Power is supplied through the provided AC adaptor.
0 Connect the provided audio connection cord to “LINE OUT” of the main unit, then insert the
white plug into the outside-input terminal (AUX terminal) of amplifier or the left input terminal
of CD input terminals. Set the input selector of amplifier to “AUX” or “CD”. When input is
to be made from the main unit to a tape deck, connect the cord to “LINE-IN” terminal.
0 Set the “VOLUME” thumbscrew at scale 7 for volume adjustment made by the amplifier.
0 When the direct input from the main unit to a tape deck is to be made, adjust the volume
with volume-level adjuster (REC LEVEL) of the tape deck
Caution:
l Before makinq connections, be sure to turn the amplifier power off.
Do not connect the main unit to the PHONO terminal of the amplifier.
CD playback in an automobile <Fig. g>
Us’e inthe car audio cassette adapter CAC-1 (optional)
When the power source is taken from a cigar socket of a car, use the optional car battery
adaptor DC-C7. It allows you to enjoy listening to music for a long time without worrying about
the battery consumption.
Insert the plug of car audio cassette adaptor CAC-1 (optional) into the “LINE OUT” terminal
of the main unit. Insert the CAC-1 to the car component deck, and turn the car component
deck into the PLAY mode.
Set the “VOLUME” thumbscrew at scale 7 for volume adjustment made by the car cassette
deck. .
Notes:
Since car battery adapters available in the market have different polarity and voltage, they
may result in troubles. (Be sure not to use a car battery adaptor other than the optional
DC-C7.1
In case the unit is used in a car, install It taking the safety in consideration, so that it does
not interfere with the driving operations.
The CAC-1 cannot be used with some car audio cassette models.
Do not leave the unit in a closed automobile where the temperature is expected to be high.
Place the unit on a soft place where automobile vibrations are not easily transmitted.
If any sound skipping occurs due to vibrations, turn on the [HOLDI switch to reduce the sound
skippinq.
