Suggestions for Safety
■ Use a standard AC wall outlet
1. Use from an AC power source of high voltage, such as for
an air conditioner, is very dangerous.
There is the possibility that a fire might be caused by making
such a connection.
2. A DC power source cannot be used.
Be sure to check the power source carefully, especially on a
ship or other place where DC is used.
■ Grasp the plug when disconnecting the power
supply cord
1. Wet hands are dangerous.
A dangerous electric shock may result if the plug is touched
by wet hands.
2. Never place heavy items on top of the power supply cord,
and never force It to bend sharply.
■ Place the unit where it will be well ventilated
Place this unit at least 10 cm (4“) away from wall surfaces, etc.
Be careful that curtains and similar materials do not obstruct the
ventilation holes.
■ Avoid places such as the following:
In direct sunlight or In other places where the temperature is
high.
In places whers there is excessive vibration or humidity.
Such conditions might damage the cabinet and/or other compo¬
nent parts and thereby shorten the unit’s service life.
■ Be sure to place the unit on a flat, level sur¬
face.
If the surface is inclined, a malfunction may result.
■ Never attempt to repair or reconstruct this
unit
A serious electric shock might occur if this unit is repaired,
disassembled or reconstructed by unauthorized persons, or if the
internal parts are accidentally touched.
■ Take particular care if children are present
Never permit children to put anything, especially metal, inside
this unit. A serious electric shock or malfunction could occur if
articles such as coins, needles, screwdrivers, etc. are inserted
through the ventilation holes, etc. of this unit.
■ If water is spilled on the unit
Be extremely careful if water is spilled on the unit, because a fire
or serious electric shock might occur. Immediately disconnect
the power cord plug, and consult with your dealer.
■ Avoid spray-type insecticides
Insecticides might cause cracks or “cloudiness” in the cabinet
and plastic parts of this unit. The gas used in such sprays might,
moreover, be ignited suddenly.
■ Never use alcohol or paint thinner
These and similar chemicals should never be used, because they
might cause flaking or cloudiness of the cabinet finish.
■ Disconnect the power supply cord If the unit
will not be used for a long time
If the unit is left for a long time with the power ON, this will not
only shorten its useful operation life, but may also cause other
troubles.
■ If trouble occurs
If, during operation, the sound is interrupted or indicators no
longer illuminate, or if abnormal odor or smoke is detected, im¬
mediately disconnect the power cord plug, and contact your
dealer or an Authorized Service Center.

AM (MW/LW) antenna connections
( AM loop antenna (included) )
Connect the AM loop antenna to the AM loop antenna terminals,
and mount it vertically to a column, a wall or rack.
• If this antenna is not properly installed, MW/LW broadcasts will
not be received.
• Be sure to connect the AM loop antenna even when an outdoor
antenna is used.
Pay attention to the following points when mounting the
antenna.
• Do not mount it horizontally (Doing so will impair reception).
• Do not mount it close to power cords, speaker wires or metal
surfaces (Doing so will result in noise).
• Do not mount it close to a tape deck. When the tape deck is be¬
ing used, chirping or beeping sounds may result.
When mounting the antenna to a column, a wall
or rack
Mount it vertically.
Move the antenna toward the right or left to find the point of best
reception.
When mounting the antenna to the unit
This type of installation may cause impaired reception or result in
signal noise. If possible, mount the antenna to a column, a wall or
rack.
Move the antenna toward the right or left to find the point of best
reception.
( AM outdoor antenna (not included) )
An outdoor antenna may be required in a mountainous region, or
if this unit is located inside a reinforced-concrete building, etc.
Use 5-12 m of vinyl-covered wire horizontally at the window, or
convenient location.
Note:
When the unit is not in use, disconnect the outdoor antenna to
prevent possible damage that may be caused by lightning. Never
use an outdoor antenna during an electrical storm.

Remote Control Transmitter
Insertion of remote control transmitter batteries
1. Open the cover.
2. Insert the batteries.
• Be sure to insert according to the
(+) and (-) indications in the
battery compartment.
• Use two UM-4, “AAA” (R03; 1.5 V)

■ Battery life
Battery life is about one year. (Battery life
may vary depending upon the frequency of
use and other conditions of use.)
The batteries should be replaced if the unit
cannot be operated even when the remote
control transmitter is brought close to the
unit.
■ Battery notes
• Be sure that batteries are inserted so that
they are placed correctly with respect to
the (+) and (—) indications in the battery
compartment. If the batteries are not in¬
serted correctly, they may leak and
damage the remote control transmitter.
• Do not use rechargeable (nickel-cadmium)
type batteries.
• Do not mix old and new batteries, or bat¬
teries of different types (carbon and
alkaline, etc.)
• If the remote control transmitter is not to be
used for a long period of time, take out the
batteries and store them in a cool, dark
place.
• Remove and dispose of worn-out batteries.
• Never attempt to recharge or short-circuit
the batteries, and do not disassemble them
or expose them to excessive heat or throw
them into a fire.
• If a battery leaks, remove both batteries
and dispose of them, and then thoroughly
clean the battery compartment before in¬
serting new batteries.
Remote control transmitter operation notes
Face It toward the remote control
signal receptor of this unit.
Be sura the transmitter part of the remote control
transmitter and the receptor part of this unit are
free from dust.
Excessive dust might prevent reception.
(Obstacles should be
avoided.)
-Other notes—-
1. D o not expose the receptor (on this unit)
to direct sunlight or other strong light,
because to do so might result In incorrect
operation.
2. D o not use a remote control transmitter
