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.

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

SAFETY INSTRUCTIONS

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.

1 To ensure the finest performance, please read this

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

2 Install your unit in a cool, dry, clean place – away from

windows, heat sources, and too much vibration, dust, moisture or cold. Avoid sources of hum (transformers, motors). To prevent fire or electrical shock, do not expose to rain and water.

3 Do not operate the unit upside-down. It may overheat,

possibly causing damage.

4 Never open the cabinet. If a foreign object drops into

the set, contact your dealer.

5 Do not use force on switches, knobs or cords. When

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.

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.

How to Connect:

Red: positive (+) Black: negative (–)

➀

Press up the tab.

➁

Insert the bare wire. [Remove approx. 5mm (1/4”) insulation from the speaker wires.]

➂

Press down the tab and secure the wire.

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).

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.
