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:

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 ensure the finest performance, please read this

manual carefully. Keep it in a safe place for future reference.

moving the set, first turn the unit off. Then gently disconnect the power plug and the cords connecting to other equipment. Never pull the cord itself.

6 Do not attempt to clean the unit with chemical solvents;

this might damage the finish. Use a clean, dry cloth.

7 Always set the volume control to “–

audio source play: increase the volume gradually to an appropriate level after the play is started.

We Want You Listening For A Lifetime

Compliance with FCC regulations does not guarantee that interference will not occur in all installations. If this product is found to be the source of interference, which can be determined by turning the unit “OFF” and “ON”, please try to eliminate the problem by using one of the following measures:

Relocate either this product or the device that is being affected by the interference.

Utilize power outlets that are on different branch (circuit breaker or fuse) circuits or install AC line filter/s.

In the case of radio or TV interference, relocate/reorient the antenna. If the antenna lead-in is 300 ohm ribbon lead, change the lead-in to coaxial type cable.

CONNECTIONS

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 components to which connections are being made.

AUDIO CONNECTIONS

When making connections between this unit and other components, be sure all connections are made correctly, that is to say L (left) to L, R (right) to R, “+” to “+” and “–” to “–”. Also, refer to the owner’s manual for each component to be connected to this unit.

CONNECTING SPEAKERS

➀

➁

➂

Connect the SPEAKERS terminals to your speakers with wire of the proper gauge, cut to be as short as possible. If the connections are faulty, no sound will be heard from the speakers. Make sure that the polarity of the speaker wires is correct, that is, + and – markings are observed. If these wires are reversed, the sound will be unnatural and will lack bass.

Do not let the bare speaker wires touch each other and do not let them touch the metal parts of this unit as this could damage this unit and/or speakers.

●

One or two speaker systems can be connected to this unit. If you connect only one speaker system, connect it to either the SPEAKERS A or B terminals.

●

Use speakers with the specified impedance shown on the rear of this unit.

ABOUT THE ACCESSORY TERMINALS

AC OUTLETS

(U.S.A., Canada Europe and General models)

............................................................2 SWITCHED OUTLETS

(Australia and U.K. models)

...............................................................1 SWITCHED OUTLET

Use these to connect the power cords from your components to this unit. The power to the SWITCHED outlets is controlled by this unit’s

POWER switch or the provided remote control transmitter’s POWER key. These outlets will supply power to any

component whenever this unit is turned on. The maximum power (total power consumption of components) that can be connected to the SWITCHED AC OUTLETS is 100 watts (200 watts for U.S.A. and General models).

How to Connect:

Red: positive (+) Black: negative (–)

Press up the tab.

➀

Insert the bare wire.

➁

[Remove approx. 5mm (1/4”) insulation from the speaker wires.] Press down the tab and

➂

secure the wire.

GND terminal (For turntable use)

Connecting the ground wire of the turntable to this terminal will minimize hum, but in some cases better results may be obtained with the ground wire disconnected.

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.

Orient so that the best reception is obtained.

* The antenna may be hung on a wall.

* The AM loop antenna should be kept being 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.
