FOR YOUR SAFETY
EUROPE
AUSTRALIA
220 V
240 V
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 threepin 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 220-240 V AC.
CAUTION
• Leave a space around the unit for sufficient ventilation.
• Avoid installation in extremely hot or cold locations, or in an area that is exposed to direct sunlight or heating equipment.
• Keep the unit free from moisture, water, and dust.
• Do not let foreign objects in the unit.
• The ventilation should not be impeded by covering the ventilation openings with items, such as newspapers, table-cloths,
curtains, etc.
• No naked flame sources, such as lighted candles, should be placed on the unit.
• Please be care the environmental aspects of battery disposal.
• The unit shall not be exposed to dripping or splashing for use.
• No objects filled with liquids, such as vases, shall be placed on the unit.
• Do not let insecticides, benzene, and thinner come in contact with the set.
• Never disassemble or modify the unit in any way.
■Notes on the AC power cord and the wall outlet.
• The unit is not disconnected from the AC power source(mains) as long as it is connected to the wall outlet, even if the unit has
been turned off.
• When disconnecting the power cord from the wall outlet, always pull the plug, not the power cord.
• Disconnect the plug from the wall outlet when not using the unit for long periods of time.
• The wall outlet shall be installed near the unit and shall be easily accessible.

Introduction
System Connections
• Do not plug the AC input cord into the wall AC outlet until all connections are completed.
• Be sure to observe the color coding when connecting audio, video and speaker cords.
• Make connections firmly and correctly. If not, it can cause loss of sound, noise or damage to the receiver.
1.
CONNECTING ANTENNAS
GND
GND
AM
LOOP
AM
LOOP
• A 75Ω outdoor FM antenna may be used to further
improve the reception. Disconnect the indoor
antenna before replacing it with the outdoor one.
• Change the position of the FM indoor antenna until you
get the best reception of your favorite FM stations.
GND
AM
LOOP
• 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.

2.
CONNECTING PHONO
�Note
• Do not connect the turntable with MC type cartridge
directly. If so, use a separate head amplifier or step-up
transformer.
3.
CONNECTING VIDEO AND AUDIO COMPONENTS
• The TV and AUX jacks may also be connected to an additional component such as a TV, DVD player, etc.
• The TAPE IN/OUT jacks can be connected to audio recording equipment such as a tape deck, an MD recorder, etc.
• The VIDEO jacks may also be connected to an additional component such as MD recorder, tape deck, etc.
�Note :
• When Sherwood CD player such as CD-772, etc. is connected to the DIGI-LINK jack for system control, you should connect the CD player to the "CD" jacks of this unit.
Because, if the PLAY button, etc. is pressed on the CD player, the CD is automatically selected as an input source on this
unit. Then play, etc. starts.
5
4.
CONNECTING PRE OUTS or MAIN INS
• You can connect either a pre amplifier or a power amplifier to this receiver.
• To achieve higher sound quality, connect the MAIN IN jacks to the pre amplifier and connect the speakers to this receiver.
• To drive speakers with higher power output, connect the PRE OUT jacks to the power amplifier and connect it to speakers.
�Note:
• When you do not use the MAIN IN and PRE OUT jacks, always connect these jacks with the supplied jumper plugs.
5.
CONNECTING DIGI LINK
• Connect this jack to the DIGI LINK jack of Sherwood CD
player such as CD-772, etc. that uses the DIGI LINK
remote control system.
6.
CONNECTING SPEAKERS
• Usally SPEAKER A terminals are used for only a pair of
speakers. When you have another pair of speakers,
SPEAKER B terminals can be used.
• Be sure to connect speakers firmly and correctly according to the channel(left and right) and the polarity (+ and -).
If the connections are faulty, no sound will be heard from
the speakers, and if the polarity of the speaker connection
is incorrect, the sound will be unnatural and lack bass.
Notes :
• For safe amplifier operation, use the speakers with
impedance of over 4Ω when you use only SPEAKER A or
B terminals and use the speakers with impedance of over
8Ω when you use both SPEAKER A and B terminals.
• Do not let the bare speaker wires touch each other or any
metal part of this unit. This could damage this unit and/or
the speakers.

7.
SWITCHED AC OUTLET
• This outlet is switched on (power-on mode) and off
(standby mode) according to power control as follows
(Maximum total capacity is 100 W (0.43A)).
Standby mode - Switched AC outlet off
Power-on mode - Switched AC outlet on
8.
AC INPUT
• Plug the supplied AC input cord into this AC input
and then into the wall AC outlet.
�Note:
• Do not use an AC input cord other than the one supplied with this unit. The AC input cord supplied is
designed for use with this unit and should not be
used with any other device.
