Chapter 1 Getting Started
Precautions
On safety
• For U.S.A. and Canadian models, operate the unit only on
120 VAC, 60 Hz.
• For Australian model, operate the unit only on 240 V AC,
50 Hz.
• Should any solid object or liquid fall into the cabinet,
unplug the unit and have it checked by qualified
personnel before operating it any further.
• Unplug the unit from the wall outlet if it is not to be used
for an extended period of time. To disconnect the cord,pull
it out by grasping the plug. Never pull the cord itself.
• One blade of the plug is wider than the other for the
purpose of safety and will fit into the power outlet only
one way. If you are unable to insert the plug fully into the
outlet, contact your dealer, (not applicable to Australian
customers)
• AC power cord must be changed only at the qualified
service shop.
• This unit is not disconnected from the AC power source as
long as it is connected to the mains outlet, even if the unit
itself has been turned off.
On operation
Before making program source connections, be sure to
turn the power switch off and unplug the unit.
Unpacking
Do not throw away the carton and packing material!
It will be an ideal container when transporting the system for
repair work, etc.
Checking the Supplied Accessories
After unpacking, check that the following accessories are
present.
• FM wire antenna...........................................................(1)
• AM loop antenna
• Remote commander RM-U141.....................................(1)
• Sony batteries SUM-3 (NS)..........................................(2)
Inserting the Batteries into the Remote
Commander
Before operating remote commander, install the batteries as
shown below.
..........................................................
(1)
To prevent internal heat buildup in the unit,
place the unit in a location with adequate air circulation.
Do not install the unit:
• near heat sources such as radiators or air ducts.
• in a place subject to direct sunlight, excessive dust,
mechanical vibration or shock.
Do not place anything on top of the cabinet.
The top ventilation holes must be unobstructed for the
proper operation of the unit and to prolong the life of its
components.
On cleaning the cabinet
Clean the cabinet, panel and controls with a soft cloth lightly
moistened with mild detergent solution. Do not use any type
of abrasive pad, scouring powder, or solvent such as alcohol
or benzine.
For the customers in the U.S.A.
For detailed safety precautions, see the "IMPORTANT
SAFEGUARDS" leaflet.
If you have any question or problem concerning your unit,
please consult your nearest Sony dealer.
To avoid damage caused by battery leakage and corrosion
When the commander will not be used for a long time,
remove the batteries.
Battery life
Normal operation can be expected about a half year using
Sony SUM-3 (NS) (size-AA), and a year using Sony AM-3
(NW) (size-AA) alkaline batteries.
When the batteries are run down, the remote commander
will not operate the unit. In this case, replace both batteries
with new ones.

Hooking Up the System
Notes on Connections
At first, this section describes about the connection with the other equipments, the antenna connection,
speaker connection and then the AC power connection.
• Do not connect the power cord to an AC outlet nor press the POWER switch before accomplishing all
other connections.
• The cable connectors should be fully inserted into the jacks. Loose connection may cause hum and
noise.
• Jacks and plugs of the connecting cord are color-coded as follows:
Red jacks and plugs: For the right channel of audio signals
White jacks and plugs: For the left channel of audio signals
Yellow jacks and plugs: For video signals

Though the wire antenna is supplied with this unit, the
higher quality sound will be obtained with 75K>hm coaxial
cable, (optional)
;ira IT ¡‘r i
For best reception
3(X)-ohtn twin-lead (not supplied)
Connecting the Antenna Ground
To prevent hum, connect the ground wire to the ANTENNA
ground terminal (/h).
When an outdoor antenna is installed, be sure to connect the
ground wire for lightning protection.
0 Connecting the AM Antenna
The AM reception is adequate with the supplied AM loop
antenna. However, the connection of insulated wire is also
available for areas with difficult AM reception.
75-ohm coaxial cable (not supplied)
When not using the outdoor
antenna
AM antenna extension
For best reception, attach a length of insulated wire (6 -15 m
long) to the AM screw connector in addition to the loop
antenna.
Page 7
(3) Connecting Speaker Systems
Connecting the AC Power
Be careful that the power consumption of equipment coimected to the outlet on the receiver does not exceed 120 watts for
US.A. and Canada models or 100 watts for Australian model.
Do not connect electrical home appliance such as an electric iron, fan, TV, or other high-wattage equipment to the outlet.

Receiving FM/AM Broadcasts
Tuning in a Station Directly — Direct Tuning
To correct the entered frequency
Repeat steps 3 to 4.
If you enter a frequency not covered by the tuning interval
The entered value is automatically rounded up or down to
the closest value covered by the tuning interval.
Tuning intervals for direct tuning are the followings:
FM: 50 kHz interval
AM: 10 kHz interval (for US.A. and Canadian models)
9 kHz interval (for Australian model)
(To switch the tuning interval between 9 kHz and 10 kHz,
see page 17.)
When the entered frequency does not exist in the
receivable frequency range
The entered digits (up to 5 digits for FM or up to 4 digits for
AM) blink in the frequency display area, and reception does
not take place.
If this occurs, press DIRECT again, and enter the correct
frequency. The frequency range of the receiver is 87.50 to
108.0 MHz for FM, and 530 to 1710 kHz with 10 kHz interval
(U.S.A. and Canadian models) or 531 to 1602 kHz with 9
kHz interval (Australian model) for AM.
When an FM stereo program is noisy
When the unit receives an FM stereo program, the STEREO
indicator lights in the display window. If the stereo program
is noisy, press FM MODE to change the mode over to
MONO. This eliminates the stereo effect, but the noise will
be greatly reduced.
To return to the stereo mode, press FM MODE again.

Use of memory pages
The memory pages (A, B and C) can be used to classify
stations according to the music category, station band, etc.
Replacing a preset station
Preset another station on the number of the station to be
replaced. The previously preset station will be erased.
IMPORTANT
The memorized station is maintained for approximately one
month even if the power cord is disconnected from the AC
power outlet. If they are erased, store the stations again.
