REMOTE CONTROL OPERATION
I-------1
■ Operations
The following operations can be performed using the remote
control transmitter.
They are identical to the operations performed using the
main unit controls.
•Operation Switch
Turn the unit on and off.
(When using the battery power, you can only turn off.)
•CD operation
Selection of CD mode, sequential play, program play, direct
access play, repeat play, skip function, search function,
program clear, pause, stop, disc tray open/close.
•Radio operation
Selection of tuner mode, band switching, manual tuning, FM
auto tuning, memory presetting, memory tuner operation,
FM mode selection.
•Tape operation
Selection of tape mode.
•Volume control
Volume up/down
When operating the unit using the remote control
transmitter press the buttons on the remote control
transmitter slowly and accurately.
■ Inserting the remote control transmitter bat¬
teries
1. Open the cover of the battery case.
2. Insert the batteries.
Batteries used: Two R03//LR03 (UM-4 or equivalent, not
included).
■ Replacement interval of remote control trans¬
mitter batteries
Although the life of the batteries will vary depending upon
the number of times that the remote control transmitter is
used, the average life based on the used of the batteries is
about 1 year.
If the remote control transmitter fails to operate when it is
held near the unit, replace the batteries with new batter¬
ies, even if one year has not elapsed.
Precautions for using the remote control trans¬
mitter
•If the unit is exposed to direct sunlight, the remote
control transmitter may sometimes fail to function.
Be sure, therefore, to keep the unit out of direct
sunlight. In such case, the maximum range of the
remote control transmitter (approx. 7 m) may some¬
times be reduced.
•If strong light falls on the remote control sensor of
the unit (e.g. high frequency type fluorescent lamp),
the signals from the remote control transmitter may
fail to be received by the unit. In such a case, take
steps to prevent strong light from falling onto the
unit.
•If there is an obstacle between the remote control
transmitter and the unit, the signals from the remote
control transmitter will be blocked off, preventing
the unit from operating.
Use the remote control transmitter in a position
directly in front of the unit so that the remote control
sensor can be seen.
•Even if the remote control transmitter is not aimed
at the unit, the unit may sometimes operate when a
button on the remote control transmitter is pressed.
This is caused by the infra-red beam being reflected
off a wall, ceiling, floor, or furniture, and striking the
remote control transmitter of the unit.
•Do not operate the remote control transmitter of this
unit near a unit which is designed to operate using a
different remote control transmitter.
•Do not simultaneously use this remote control transmit¬
ter and one or more remote control transmitters in¬
tended either for the same type of unit or for another
type of unit, such as a television set.
•If you operate the remote control transmitter near the
unit when listening to an AM broadcast, noise may be
heard. In such a case, hold the remote control transmit¬
ter at a sufficient distance from the unit so that noise is
not heard.
•Do not disassemble the remote control transmitter or
touch any of the components inside it.
Do not place a heavy object on the remote control
transmitter or leave it exposed to direct sunlight or in a
hot location.
•Do not spill liquids on the remote control transmitter.
This may cause damage to the remote control trans¬
mitter.

INSTALLING THE DRY BATTERIES FOR MEMORY BACK-UP
This is a function which preserves the preset memory and most-recent memory functions. In the event of a power failure, or if the
AC mains cord is disconnected from the household AC mains outlet (during AC operation), or should the batteries fail, the memory
back-up batteries will preserve the preset memory and the most-recent memory functions of this unit.
■ Memory back-up batteries (four R6/LR6)
1. Open the memory back-up battery compartment cover.
2. Insert four “R6/LR6’’ size (UM-3 or equivalent, not included) batteries into the battery compartment, making sure that the
batteries are installed in the designated numerical order and that the proper polarities are maintained.
3. Close the cover.
The life of the memory back-up batteries is about one year.
While exchanging the memory back-up batteries, be sure to connect the AC mains cord both to the unit and household AC
mains outlet.

•To prevent erasing the memory
In case the memory back-up batteries are not used, power
failure (when using AC mains) or the following operations
cause the erasure of the memory:
When using AC mains: unplugging the AC mains cord from
the household AC mains outlet.
When using battery power ("R20/LR20’'): inserting the AC
mains cord only into the AC socket of this unit.
If one of the above cases occurs, enter the program into
the memory again.
In order to avoid the accidental erasure of the program in
the memory, using the memory back-up batteries (4 “R6/
LR6’’ size, UM-3 or equivalent, not included) is recom¬
mended.
•Battery removal
Press the © side of the no. 4’s battery.

POWER SOURCE
■ Battery operation (ten R20/LR20)
Insert ten “R20/LR20" size (UM-1 or equivalent, not included) batteries into the battery compartment, making sure that the
batteries are installed in the designated numerical order and that the proper polarities are maintained.
•Battery life
The amount of light provided by the operation/battery check/
AC connection indicator is a good indication as to how much
longer the batteries can be used.
•Press the operation switch to turn on the unit.
When the operation/battery check/AC connection indicator
goes out or dims, replace all batteries with new ones.

Important note:
If you cannot open the cassette compartment cover and
eject the cassette tape when running this unit on batteries,
replace the batteries with new ones, or use the AC power
source, and then perform the operation once again.

■ Car Battery Oparation
1. Insert the plug of the car battery cord into the DC Input
Jack.
2. Plug the other end into the cigarette lighter socket in your
car.
Upon plugging the car battery cord into the DC Input
Jack, the unit will automatically switch from internal
battery to car battery operation.

PRECAUTIONS
•If the set Is not used for a long period of time or Is
used only from an AC mains source, remove all the
batteries to prevent potential damage due to possible
battery leakage.
•Avoid using or placing this unit near sources of heat. Do
not leave it in an automobile exposed to direct sunlight for
a long time with the doors and windows closed as this may
deform the cabinet.
•Avoid cuts, scratches, or poor connections in the AC
mains cord, as they may result in possible fire or electric
shock hazard. Also, excessive bending, pulling or splicing
of the cord should be avoided.
•Do not unplug the AC mains cord by pulling on the cord. To
do so may cause premature failure or shock hazard.
•Do not operate the set on AC mains in a bathroom, as a
potential shock hazard may result.
To prevent possible damage to this unit
•Load new batteries with their polarities (® and 0)
aligned correctly.
•Do not apply heat to batteries, or internal short-
circuit may occur.
•If this unit is not to be used for a long period of time,
or used on AC mains supply, remove all batteries
and store them in a cool and dry place.
• Remove spent batteries immediately.
•Do not use old and new batteries together. Also
never use an alkaline battery with a manganese
battery.
•When not in use, disconnect the AC mains cord from the
AC mains outlet.
Operation switch
(OPR/BATT-STDBY (!))
Press to switch the unit from on to standby mode or vice
versa. In standby mode, the unit is still consuming a small
amount of power.
WARNING:
TO REDUCE THE RISK OF FIRE OR ELECTRIC
SHOCK, DO NOT EXPOSE THIS APPLIANCE TO
RAIN OR MOISTURE.
BASIC OPERATING PROCEDURE
■ XBS system (Extra bass system)
When the XBS level control is adjusted, the level of the
dynamic low frequency sound range is boosted.
Using this system with the tone control helps you to get
more dynamic sounds.
■ Graphic equalizer
It allows you to tailor the frequency response of the unit to
compensate for room acoustics and other factors which
affect frequency response. The overall tone can be altered
by adjusting the controls which control the following fre¬
quency bands:
330 Hz, 1 kHz, 3.3 kHz, 10 kHz.
Positioning the control to the side of the detent will
amplify the corresponding frequency band; the side will
attenuate it.
■ After use
Be sure to reduce the volume level, and turn off by pressing
the operation switch.
■ Headphones connection
(not included)
•Avoid listening for prolonged periods of time to prevent
hearing damage.
•Speakers are automatically cut off when the headphones
are connected.
