•

The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert you to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is intended to alert you to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance.

SAFETY INSTRUCTIONS (U.S.A.)

1 Read Instructions – All the safety and operating

instructions should be read before the unit is operated.

2 Retain Instructions – The safety and operating instructions

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;

B. Objects have fallen, or liquid has been spilled into the unit;

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

E. The unit has been dropped, or the cabinet damaged.

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.

Note to CATV system installer (U.S.A.):

This reminder is provided to call the CATV system installer's attention to Article 820-40 of the NEC that provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical.

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 sensitive hearing. Since hearing damage from loud sounds is

often undetectable until it is too late, YAMAHA and the Electronic Industries Association’s 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.

Before attempting to make any connections to or from this unit, be sure to first switch OFF the power to this unit and to any other
