Introduction

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 : TO REDUCE THE RISK OF

ELECTRIC SHOCK, DO NOT

REMOVE COVER (OR BACK).

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

equipment.

WARNING

UNPACKING AND INSTALLATION

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

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

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.

FOR YOUR SAFETY

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

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.

• 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 cords to the L(left) and the red RCA pin cords 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.
