batteries with correct
polarity.
i
I
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), and a year using Sony AM-3 (NW)
alkaline batteries.
When the batteries are run down, the remote commander
will not operate the unit. In this case, replace batteries with
new ones.

Hooking Up the System
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

For areas with difficult AMI reception
In areas with troubled reception, connect a 6 to 15-meter
(20 to 50-foot) insulated wire to the AM antenna terminal.
Extend this out of doors if possible, keeping the greater
portion horizontal.
(There is no need to disconnect the supplied antenna.)
Connecting the Antenna Ground
To prevent hum. connect the ground wire to ANTENNA
ground terminal (7)7).
When an outdoor antenna is installed, be sure to connect
the ground wire for lightning protection.
Page 8
Hooking Up the System
Connecting Speaker Systems
Front, rear and center speakers can be connected to this unit.
Speaker impedance and power capability
This receiver is designed to work best with speakers having
nominal impedance from 8 to 16 ohms. Be sure to use a
speaker system with adequate nominal impedance and
power handling capabilities.
When using two center speakers, use the speakers having
nominal impedance from 4 to 16 ohms.
Also, use all speakers to be connected with the equal
efficiency.
8
Note
When connecting the speaker cord to the speaker terminal,
make sure that the polarity (+ and -) of the speaker cord is
correct. If the polarity is reversed at either speaker, the
sound will be distorted and will lack bass.
Page 9
Connecting to the AC Power Outlet
Connect the AC power cord to the wall outlet last of all.
By connecting the power cord of th^ other audio equipment
to SWITCHED AC OUTLET, this unit can supply the power
source to the other audio equipmen't.
Caution
Be careful that the total power consumption of each
equipment connected to the outlets on the receiver does not
exceed 120 watts for USA and Canada models or 100 watts
for UK model.
Do not connect electrical home appliances such as an
jlectric iron. fan. TV. or other high-wattage equipment to
hese outlets.
