Introduction

U N P A C K I N G A N D

Congratulations on Your Purchase!

Your new high fidelity receiver is designed to deliver maximum enjoyment and years of trouble free service.

Please take a few moments to read this manual thoroughly. It will explain the features and operation of your unit and help ensure a trouble free installation.

Please unpack your unit carefully. We recommend that you save the carton and packing material. They will be helpful if you ever need to move your unit and may be required if you ever need to return it for service. Your unit is designed to be placed in a horizontal position and it is important to allow at least two inches of space behind your unit for adequate ventilation and cabling convenience.

To avoid damage, never place the unit near radiators, in front of heating vents, in direct sunlight, or in excessively humid or dusty locations. Connect your complementary components as illustrated in the following section.

CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

CAUTION : TO REDUCE THE RISK OF

ELECTRIC SHOCK, DO NOT

REMOVE COVER (OR BACK).

NO USER-SERVICEABLE PARTS

INSIDE. REFER SERVICING TO

QUALIFIED SERVICE PERSONNEL.

This symbol is intended to alert the user 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.

This symbol is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance.

WARNING

To reduce the risk of fire or electric shock, do not expose this appliance to rain or moisture.

Caution : Do not block ventilation openings or stack other equipment on the top.

FOR U.S.A.

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.

FCC INFORMATION

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 energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.

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 or more 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.

CAUTION: Any changes or modifications in construction of this device which are not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

Caution regarding placement

(Except for U.S.A. and Canada)

To maintain proper ventilation, be sure to leave a space around the unit (from the largest outer dimensions including projections) equal to, or greater than, shown below.

Left and right panels: 5 cm

Rear panel: 10 cm

Top panel: 20 cm

READ THIS BEFORE OPERATING

FOR U.S.A. AND CANADA ................................. 120 V

FOR YOUR SAFETY

Units shipped to the U.S.A. and Canada are designed for operation on 120 V AC only.

Safety precaution with use of a polarized AC plug.

However, some products may be supplied with a nonpolarized plug.

CAUTION :

To prevent electric shock, match wide blade of plug to wide slot, fully insert.

ATTENTION : Pour eviter les choc electriques, introduire la lame la plug large de la borne correspondante de la prise et poussre jusqu’au fond.

FOR OTHER COUNTRIES ........................ 115 V/230 V

FOR YOUR SAFETY

Units shipped to countries other than the above countries are equipped with an AC voltage selector switch on the rear panel. Refer to the following paragraph for the proper setting of this switch.

AC VOLTAGE SELECTION

This unit operates on 115/230 V AC. The AC voltage selector switch on the rear panel is set to the voltage that prevails in the area to which the unit is shipped.

Before connecting the power cord to your AC outlet, make sure that the setting position of this switch matches your line voltage. If not, it must be set to your voltage in accordance with the following direction.

AC voltage selector switch

FOR CHINA, EUROPE AND AUSTRALIA ........ 220V/230V/240V

FOR YOUR SAFETY

Units shipped to China are designed for operation on

220 V AC only.

Units shipped to Australia are designed for operation on 240 V AC only.

To ensure safe operation, the three-pin plug supplied must be inserted only into a standard three-pin power point which is effectively earthed through the normal household wiring. Extension cords used with the equipment must be three-core and be correctly wired to provide connection to earth.

Improper extension cords are a major cause of fatalities. The fact that the equipment operates satisfactorily does not imply that the power point is earthed and that the installation is completely safe.

For your safety, if in any doubt about the effective earthing of the power point, consult a qualified electrician.

PAN-EUROPEAN UNIFIED VOLTAGE

All units are suitable for use on supplies 230-240 V

AC.

Move switch lever to match your line voltage with a small screwdriver or other pointed tool.

System Connections

Do not plug the AC input cord into the wall AC outlet until all connections are completed.

Be sure to connect the white RCA pin cord to the L(left) and the red RCA pin cord to the R(right) jacks when making audio connections.

Change the position of the FM indoor antenna until you get the best reception of your favorite FM stations.

A 75 Ω outdoor FM antenna may be used to further improve the reception.

Disconnect the indoor antenna before replacing it with the outdoor one.

Place the AM loop antenna as far as possible from the receiver, TV set, speaker cords and the AC input cord and set it to a direction for the best reception.

If the reception is poor with the AM loop antenna, an AM outdoor antenna can be used in place of the AM loop antenna.

Make connections firmly and correctly. If not, it can cause loss of sound, noise or damage to the receiver.

If the electricity fails or the AC input cord is left unplugged for more than 2 weeks, the memorized contents will be cleared.

Should this happen, memorize them again.

Troubleshooting Guide

If a fault occurs, run through the table below before taking your receiver for repair.

If the fault persists, attempt to solve it by switching the receiver off and on again. If this fails to resolve the situation, consult your dealer. Under no circumstances should you repair the receiver yourself as this could invalidate the warranty.

PROBLEM

No power

No sound

Stations cannot be received

Preset stations cannot be received

Poor FM reception

POSSIBLE CAUSE

• The AC input cord is disconnected.

• Poor connection at AC wall outlet or the outlet is inactive.
