should be retained for future reference.
3 Heed Warnings – All warnings on the unit and in the
operating instructions should be adhered to.
4 Follow Instructions – All operating and other instructions
should be followed.
5 Water and Moisture – The unit should not be used near
water – for example, near a bathtub, washbowl, kitchen
sink, laundry tub, in a wet basement, or near a swimming
pool, etc.
6 Carts and Stands – The unit should be used only with a
cart or stand that is recommended by the manufacturer.
6A A unit and cart combination should
be moved with care. Quick stops,
excessive force, and uneven
surfaces may cause the unit and
cart combination to overturn.
7 Wall or Ceiling Mounting – The unit
should be mounted to a wall or ceiling only as
recommended by the manufacturer.
8 Ventilation – The unit should be situated so that its location
or position does not interfere with its proper ventilation.
For example, the unit should not be situated on a bed,
sofa, rug, or similar surface, that may block the ventilation
openings; or placed in a built-in installation, such as a
bookcase or cabinet that may impede the flow of air
through the ventilation openings.
9 Heat – The unit should be situated away from heat sources
such as radiators, stoves, or other appliances that produce
heat.
10 Power Sources – The unit should be connected to a power
supply only of the type described in the operating
instructions or as marked on the unit.
11 Power-Cord Protection – 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, paying
particular attention to cords at plugs, convenience
receptacles, and the point where they exit from the unit.
12 Cleaning – The unit should be cleaned only as
recommended by the manufacturer.
13 Nonuse Periods – The power cord of the unit should be
unplugged from the outlet when left unused for a long
period of time.
14 Object and Liquid Entry – Care should be taken so that
objects do not fall into and liquids are not spilled into the
inside of the unit.
15 Damage Requiring Service – The unit should be serviced
by qualified service personnel when:
A. The power-supply cord or the plug has been damaged;
or
B. Objects have fallen, or liquid has been spilled into the unit;
or
C. The unit has been exposed to rain; or
D. The unit does not appear to operate normally or exhibits a
marked change in performance; or

16 Servicing – The user should not attempt to service the unit
beyond those means described in the operating
instructions. All other servicing should be referred to
qualified service personnel.
17 Power Lines – An outdoor antenna should be located away
from power lines.
18 Grounding or Polarization – Precautions should be taken
so that the grounding or polarization is not defeated.
19 Outdoor Antenna Grounding – If an outside antenna is
connected to this unit, be sure the antenna system is
grounded so as to provide some protection against voltage
surges and built-up static charges. Article 810 of the
National Electrical Code, ANSI/NFPA 70, provides
information with regard to proper grounding of the mast
and supporting structure, grounding of the lead-in wire to
an antenna discharge unit, size of grounding conductors,
location of antenna discharge unit, connection to
grounding electrodes, and requirements for the grounding
electrode.

CAUTION: READ THIS BEFORE OPERATING YOUR UNIT
1 To assure the finest performance, please read this
manual carefully. Keep it in a safe place for future
reference.
2 Install this unit in a cool, dry, clean place – away from
windows, heat sources, sources of excessive vibration,
dust, moisture and cold. Avoid sources of humming
(transformers, motors). To prevent fire or electrical
shock, do not expose the unit to rain or water.
3 Never open the cabinet. If something drops into the set,
contact your dealer.
4 Do not use force on switches, controls or connection
wires. When moving the unit, first disconnect the power
plug and the wires connected to other equipment. Never
pull the wires themselves.
5 The openings on the cabinet assure proper ventilation of
the unit. If these openings are obstructed, the
temperature inside the cabinet will rise rapidly and
eventually damage the circuits. Therefore, avoid placing
objects against these openings and do not install the unit
where the flow of air through the ventilation openings
could be impeded.

We Want You Listening For A Lifetime (U.S.A.)
YAMAHA and the Electronic Industries Association’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

Consumer Electronics Group recommend you to
avoid prolonged exposure from excessive
volume levels.

This product complies with the radio frequency interference requirements of the Council Directive 82/499/EEC and/or
87/308/EEC.
The apparatus is not disconnected from the AC power source as long as it is connected to the wall outlet, even if the apparatus
itself is turned off.
For U.K. customers
If the socket outlets in the home are not suitable for the plug supplied with this appliance, it should be cut off and an appropriate 3
pin plug fitted. For details, refer to the instructions described below.
Note: The plug severed from the mains lead must be destroyed, as a plug with bared flexible cord is hazardous if engaged in a live
socket outlet.
SPECIAL INSTRUCTIONS FOR U.K. MODEL
IMPORTANT:
The wire in the mains lead are coloured in accordance with the following code:
Blue: NEUTRAL
Brown: LIVE
The colours of the wires in the mains lead of this apparatus may not correspond with the coloured markings identifying the
terminals in your plug. Proceed as follows: the wire which is coloured BLUE must be connected to the terminal which is marked
with the letter N or coloured BLACK. The wire which is coloured BROWN must be connected to the terminal which is marked
with the letter L or coloured RED. Making sure that neither core is connected to the earth terminal of the three pin plug.

ANTENNA CONNECTIONS
●
Each antenna should be connected to the designated terminals correctly, referring to the following figure.
●
Both AM and FM indoor antennas are included with this unit. In general, these antennas will probably provide sufficient signal
strength. Nevertheless, a properly installed outdoor antenna will give clearer reception than an indoor one. If you experience
poor reception quality, an outdoor antenna may result in improvement.
Connecting the AM loop antenna
* The AM loop antenna should be placed apart from the main unit. The antenna may be hung on a wall.
* The AM loop antenna should be kept connected, even if an outdoor AM antenna is connected to this unit.
GND terminal
For maximum safety and minimum interference, connect the
GND terminal to a good earth ground. A good earth ground is
a metal stake driven into moist earth.
Notes
●
When connecting the indoor
FM antenna, make sure that
the grooved part of the
connector hole is facing
downward.
●
If you need an outdoor
FM antenna to improve
FM reception quality, either 300-ohm feeder or coaxial cable
may be used. In locations troubled by electrical
interference, coaxial cable is preferable.
Orient so that the best
reception is obtained.
