Timer operations
Using the sleep timer.................................................13
Before using this unit please read these operating instructions care
fully. Take special care to follow the warnings indicated on the unit
itself as well as the safety suggestions listed below.
Afterwards keep them handy for future reference.
Safety
1. Power Source—The unit should be connected to power supply
only of the type described in the operating instructions or as
marked on the unit.
2. Polarization—If the unit is equipped with a polarized AC power
plug (a plug having one blade wider than the other), that plug
will fit into the AC outlet only one way. This is a safety feature.
If you are unable to insert the plug fully into the outlet, try
reversing the pltig. If the plug should still fail to fit, contact your
electrician to replace your obsolete outlet. Do not defeat the safety
' purpose of the polarized plug.
3. Power Cord Protection—AC power supply cords should be
routed so that they are not likely to be walked on or pinched by
items placed upon or against them. Never take hold of the plug
or cord if your hand is wet, and always grasp the plug body
when connecting or disconnecting it.
4. Nonuse Periods—When the unit is not used, turn the power off.
When left unused for a long period of time, the unit should be
unplugged from the household AC outlet.

ample, near a bathtub, washbowl, swimming pool, or the like.
Damp basements should also be avoided.
2. Condensation—Moisture may form on the lens in the following
conditions...
• immediately after a heater has been turned on.
• in a steamy or very humid room.
• when the unit is suddenly moved irom a cold environment to
a warm one.
If moisture forms inside this unit, it may not operate properly.
To correct this problem, turn on the power and wait about one
hour for the moisture to evaporate,
3. Heat—The unit should be situated away from heat sources such
as radiators and the like. It also should not be placed in tempera
tures less than 5°C (41°F) or greater than 35°C (95°F).

1. Ventilation—The unit should be situated so that its location or
position does not interfere with its proper ventilation. Allow 10
cm (4" ) clearance from the rear of the unit.
2. Foreign Material—Care should be taken so that objects do not
fall into and liquids are not spilled into the unit. Do not subject
this imit to excessive smoke, dust, mechanical vibration, or shock.
3. Magnetism—The uirit should be situated away from equipment
or devices that generate strong magnetic fields.
4. Stacking—Do not place heavy objects, other than system com
ponents, on top of the unit.
5. Surface—Place the unit on a flat, level surface,
6. Carts and Stands—The unit should be used only
with a cart or stand that is recommended by the

THE FOLLOWING PHRASES ARE APPLIED ONLY FOR U.S.A.:
CAUTION:
This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to Part 15 of the
FCC Rules.
These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency en
ergy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio commu
nications. However, there is no guarantee that interference will
not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on,
the user is encouraged to try to correct the interference by one
of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician
for help.
FCC Notice: This system complies with new Part 15, except for
the radio receiver, which complies with old Part 15, Subpart C
of the FCC Rules, Operation is subject to the following two
conditions; (1) This device may not cause harmful interference,
and (2) this device must accept any interference received, in
cluding interference that may cause undesirable operation. The
radio receiver is not subject to above item (2).
Any unauthorized changes or modifications to this equipment
would void the user's authority to operate this device.

Precautions
Concerning the remote control
I
GO
Listening caution
Selecting fine audio equipment such as the unit you've just pur
chased is only the start of your musical enjoyment. Now it's time to
i
consider how you can maximize the fun and excitement your equip
ment offers. This manufacturer and the Electronic Industries Associ
ation's Consumer Electronics Group want you to get the most out
of your equipment by playing it at a safe level. One that lets the
sound come through loud and clear without annoying blaring or
distortion—and, most importantly, without affecting your sensitive
hearing.
We recommend you to avoid prolonged exposure to excessive noise,
Sound can be deceiving. Over time your hearing "comfort level"
adapts to higher volumes of sound. So what sounds "normal" can
actually be loud and harmful to your hearing.
Guard against this by setting your equipment at a safe level BEFORE
your hearing adapts.
To establish a safe level:
• Start your volume control at a low setting.
• Slowly increase the sound until you can hear it comfortably and
clearly, and without distortion.
Once you have established a comfortable sound level:
• Set the dial and leave it there.
Taking a minute to do this now will help to prevent hearing dam
age or loss in future. After all, we want you listening for a lifetime.
Battery installation
Use of batteries
Do not mix old and new batteries, or batteries of different types
(manganese and alkaline, etc.).
Never subject batteries to excessive heat or flame; do not attempt
to disassemble them; and be sure they are not short-circuited.
If the remote control is not to be used for a long period of time,
remove the batteries and store them in a cool, dark place.
Do not attempt to recharge alkaline or manganese batteries.
Do not use rechargeable type batteries.
Battery life
The battery life is about one year.
The batteries should be replaced if commands from the remote
control transmitter do not operate the unit even when the transmitter
is held close to the front panel.

or to the bright light of an invertor fluorescent light.
Take care to keep the remote control signal sensor and end of the
remote control unit free from dust.
If this system is installed in a rack with glass doors, the glass
door's thickness or color might make it necessary to use the
remote control a shorter distance from the system.
To prevent damage

Power sources
Using a household AC outlet
Connect the included AC power cord to the AC socket of the unit and
your household AC outlet.
Using batteries (not included)
Disconnect the AC power cable from the AC IN- socket on the rear
panel, and insert eight R20/LR20 ("D" size, UM-1, not included)
batteries in the order numbered as illustrated.
How to remove the batteries B
When to replace the batteries:
When the batteries are weak:
• The display of the front panel will start to flash "
• The unit will automatically turn itself off, then ''UOV
appeared on the display.
In those cases, replace all batteries with new ones.
If the unit is not going to be used for a prolonged period of time when
a household AC outlet is used to power it, disconnect the power cable
to conserve power.
will be
Memory back-up batteries
In the event of a power failure, or if the AC power cable is disconnected
from the household AC outlet (during AC operation), or should the
batteries fail, the memory back-up batteries will preserve the preset
memory of this unit.
Battery installation B
Insert four R6/LR6 ("AA" size, UM-3, 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.
The life of the memory back-up batteries can be prolonged by
keeping the AC power cable plugged in the household AC outlet
at all times.
When disconnecting the AC power cable, switch off the power
first by setting the SELECTOR to TAPE/GIS , The life of the memory
back-up batteries is reduced if the AC power cable is disconnected
from a household AC outlet with the power still supplied.
Battery removal B
Battery life
The life of the memory back-up batteries is about one year.
