CHECKING  THE  OPERATION
When checking the operation of this unit, connect a USB device 
to this unit.
Refer to the support site written in the operating instructions for 
the details about the compatibility of a USB device.

The unit may not function properly if the 
connectors between the unit and the front panel 
are not clean. In order to prevent this, detach the 
front panel (page 6) and clean the connectors with 
a cotton swab. Do not apply too much force. 
Otherwise, the connectors may be damaged.

ˎ For safety, turn off the ignition before cleaning the 

connectors, and remove the key from the ignition 
switch.

ˎ Never touch the connectors directly with your fingers 

or with any metal device.

You can cancel the demonstration display which 
appears when the source is off and the clock is 
displayed.

1

Press MENU, rotate the control dial to 
select [SET GENERAL], then press it.

2

Rotate the control dial to select [SET 
DEMO], then press it.

3

Rotate the control dial to select [SET 
DEMO-OFF], then press it.

Cautions

ˎ Run all ground (earth) leads to a common 

ˎ Do not get the leads trapped under a screw, or 

caught in moving parts (e.g., seat railing).

ˎ Before making connections, turn the car ignition 

off to avoid short circuits.

ˎ Connect the power supply lead ʖ to the unit and 

speakers before connecting it to the auxiliary 
power connector.

ˎ Be sure to insulate any loose unconnected leads 

with electrical tape for safety.

ˎ Choose the installation location carefully so that 

the unit will not interfere with normal driving 
operations.

ˎ Avoid installing the unit in areas subject to dust, 

dirt, excessive vibration, or high temperature, 
such as in direct sunlight or near heater ducts.

ˎ Use only the supplied mounting hardware for a 

safe and secure installation.

Note on the power supply lead (yellow)
When connecting this unit in combination with other 
stereo components, the amperage rating of the car 
circuit to which the unit is connected must be higher 
than the sum of each component’s fuse amperage 
rating.

Adjust the mounting angle to less than 45°.

Subwoofer Easy Connection

You can use a subwoofer without a power amplifier 
when it is connected to a rear speaker cord.

ˎ Preparation of the rear speaker cords is required.

ˎ Use a subwoofer with an impedance of 4 to 8 ohms, 

and with adequate power handling capacities to 
avoid damage.

Memory hold connection

When the yellow power supply lead is connected, 
power will always be supplied to the memory

When replacing the fuse, be sure 
to use one matching the 
amperage rating stated on the 
original fuse. If the fuse blows, 
check the power connection and 
replace the fuse. If the fuse blows 
again after replacement, there 
may be an internal malfunction. In such a case, 
consult your nearest Sony dealer.

ɞ To a common ground (earth) point

First connect the black ground (earth) lead, then 
connect the yellow and red power supply leads.

ɟ To the +12 V power terminal which is 

energized at all times
Be sure to first connect the black ground (earth) 
lead to a common ground (earth) point.

energized when the ignition switch is set to 
the accessory position
If there is no accessory position, connect to the 
+12 V power (battery) terminal which is 
energized at all times.
Be sure to first connect the black ground (earth) 
lead to a common ground (earth) point.
