(XAV-E722)
Cautions
Run all ground (earth) leads to a common ground 
(earth) point.
This unit is designed for negative ground (earth) 12 V 
DC operation only.
Do not disassemble or modify the unit.
Do not install in locations which interfere with airbag 
operation.
Do not get the leads under a screw, or caught in moving 
parts (e.g. seat railing).
Before making connections, turn the car ignition off to 
avoid short circuits.
Connect the power supply connection cable 
 to the 
unit and speakers before connecting it to the auxiliary 
power connector.
Be sure to insulate any loose unconnected leads with 
electrical tape for safety.
Do not press on the LCD when installing the unit.
Install the unit with the monitor facing straight 
forward; do not install it at a slanted angle.
Keep the protection caps attached to the connector 
terminals of the audio connection cable 
 if the 
connectors are not in use.
When you remove a protection cap to use a connector 
of the audio connection cable 
, be careful to avoid 
short-circuiting the power supply.
Notes 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.
If no car circuits are rated high enough, connect the 
unit directly to the battery.
Connection example  
Notes (
-A)
Be sure to connect the ground (earth) lead before connecting the 
amplifier.
The alarm will only sound if the built-in amplifier is used.
Note (
-B)
You cannot use multiple auxiliary devices simultaneously, even if they 
are connected to different terminals.
Connection diagram  
To AMP REMOTE IN of an optional power 
amplifier
This connection is only for amplifiers. Connecting any other system 
may damage the unit.
To the interface cable of a car telephone
To the parking brake switch cord
To an auxiliary device such as a portable media 
player, game console, etc. (not supplied)
Tip
You can use an RCA cord (not supplied) to connect auxiliary devices.
To the +12 V power terminal of the car’s rear 
lamp lead (only when connecting the rear view 
camera)
Warning
If you have a power antenna (aerial) without a relay box, 
connecting this unit with the supplied power supply 
connection cable 
 may damage the antenna (aerial).
Notes on the control and power supply leads
The power antenna (aerial) control lead (blue) supplies +12 V DC when 
you turn on the tuner, or when you activate the AF (Alternative 
Frequency) or TA (Traffic Announcement) function.
If your car has a built-in FM/MW/LW antenna (aerial) in the rear/side 
glass, connect the power antenna (aerial) control lead (blue) or the 
accessory power supply lead (red) to the power terminal of the 
antenna (aerial) booster. For details, consult your car dealer.
A power antenna (aerial) without a relay box cannot be used with this 
unit.
Memory hold connection
When the yellow power supply lead is connected, power will always be 
supplied to the memory circuit even when the ignition switch is turned 
off.
Notes on speaker connection
Before connecting the speakers, turn the unit off.
Use speakers with an impedance of 4 to 8 ohms, and with adequate 
power handling capacities to avoid damage.
Do not connect the speaker terminals to the car chassis, or connect the 
terminals of the right speakers with those of the left speakers.
Do not connect the ground (earth) lead of this unit to the negative (–) 
terminal of a speaker.
Do not attempt to connect the speakers in parallel.
Connect only passive speakers. Connecting active speakers (with 
built-in amplifiers) to the speaker terminals may damage the unit.
To avoid a malfunction, do not use the built-in speaker leads installed 
in your car if they feature a common negative (–) lead for the right and 
left speakers.
Do not connect the unit’s speaker leads to each other.
Notes on connection
If “Output connection failure.” appears in the display, make sure the 
speaker and amplifier are connected correctly.
To use the monitor for the rear seats, connect the parking brake switch 
cord to the ground (earth).
