Transportation bracket removal
Be sure to remove the transportation brackets before
use (installation).
Use round head screws (5 mm
6 mm) for installation.

Identify all leads
The fi rst step in installation is to identify all the car wires
you will use when hooking up this unit.
As you identify each wire, we suggest that you label it
using masking tape and a permanent marker. This will
help avoid confusion when making connections later.
Note:
Do not connect the power connector to this unit until
you have made all connections. If there are no plastic
caps on the hooking wires, insulate all exposed leads
with electrical tape until you are ready to use them.
Identify the leads in the following order.
Power lead
If your car has a radio or is
pre-wired for one:
Cut the connector wires one at a
time from the plug (leaving the
leads as long as possible) so
that you can work with individual
leads. Turn the ignition on to the
accessory position, and ground
one lead of the test bulb to the
chassis.
Touch the other lead of the test bulb to each of the
exposed wires from the cut radio connector plug. Touch
one wire at a time until you fi nd the outlet that causes
the test bulb to light.
Now turn the ignition off and then on. If the bulb also
turns off and on, that outlet is the car power lead.
If your car is not wired for an audio unit:
Go to the fuse block and fi nd the fuse port for radio
(RADIO) accessory (ACC) or ignition (IGN).
Battery lead
If this unit has a yellow lead, you will need to locate
the car’s battery lead. Otherwise you may ignore this
procedure. (The yellow battery lead provides continuous
power to maintain a clock or other functions.)
If your car has a radio or is pre-wired for one:
With the ignition and headlights off, identify the car
battery lead by grounding one lead of the test bulb to the
chassis and checking the remaining exposed wires from
the cut radio connector plug.
If your car is not wired for an audio unit:
Go to the fuse block and fi nd the fuse port for the
battery, usually marked BAT.
Speakers (not supplied)
Identify the car speaker leads. There are two leads for
each speaker, usually color coded.
A handy way to identify the speaker leads and the
speaker they are connected to is to test the leads using a
1.5 V AA battery as follows.
Hold one lead against one pole of the battery and stroke
the other lead across the other pole. You will hear a
scraping sound in a speaker if you are holding a speaker
lead.
If not, keep testing different lead combinations until you
have located all the speaker leads. When you label them,
include the speaker location for each.
Connect all leads
Now that you have identifi ed all the wires in the car,
you’re ready to begin connecting them to this unit wires.
Electrical Connections (
page 10 – 11) shows the
proper connections and color coding of the leads.
We strongly recommend that you test the unit before
making a fi nal installation.
You can set the unit on the fl oor and make temporary
connections to test the unit. Use electrical tape to cover
all exposed wires.
Important:
Connect the red power lead last, after you have made
and insulated all other connections.
Ground
Connect the black ground lead of the power connector to
the metal car chassis.
Speakers
Connect the speaker wires. See the wiring diagram for
the proper hookups. Follow the diagram carefully to
avoid damaging the speakers and this unit.
The speakers used must be able to handle more than
50 W of audio power. If using optional audio power,
the speakers should be able to handle the maximum
amplifi er output power. Speakers with low input ratings
can be damaged.
Speaker impedance should measure 4 – 8
, which is
typically marked on most speakers. Lower or higher
impedance speakers will affect output and can cause
both speaker and this unit damage.
Battery
Connect the yellow battery lead to the correct radio wire
or to the battery fuse port on the fuse block.
Equipment
Connect any optional equipment according to the
instructions furnished with the equipment. Read the
operating and installation instructions of any equipment
you will connect to this unit.
Power
Connect the red power lead to the correct car radio wire
or to the appropriate fuse port on the fuse block.
If this unit functions properly with all these connections
made, disconnect the wires and proceed to the fi nal
installation.
Final installation
Lead connections
Connect all wires, making sure that each connection is
insulated and secure. Bundle all loose wires and fasten
them with tape so they will not fall down later. Now
insert this unit into the mounting collar.
Congratulations! After making a few fi nal checks, the
new unit is ready for use.
Final checks
1. Make sure that all wires are properly connected and
insulated.
2. Make sure that this unit is securely held in the
mounting collar.
3. Turn on the ignition to check the unit for proper
operation.
If you have diffi culties, consult your nearest authorized
professional installer for assistance.
Precautions
Disconnect the cable from the negative (–) battery
terminal.
Unit should be installed in a horizontal position
with the front end up at a convenient angle, but less
than 30°.
0 – 30°
This unit should be professionally installed. In case of
diffi culty, please consult with your nearest professional
installer.
1. This unit only operates in a 12 V DC negative ground
system.
2. Follow the electrical connections carefully
(
page 10 – 11). Failure to do so may result in
damage to the unit.
3. Connect the power lead after all other connections are
made.
4. Be sure to connect the battery lead (yellow) to the
positive terminal (+) of the battery or fuse block (BAT)
terminal.
5. Insulate all exposed wires to prevent short circuiting.
6. Secure all loose wires after installing the unit.
7. Please carefully read the operating and installation
instructions of the respective equipment before
connecting it to this unit.
Warning
This product is designed for operation with a negative
grounded 12 V DC battery system. Never operate
this product with other battery systems, especially
a 24 V DC battery system. If it is used in the wrong
type of car, it may cause a fi re or an accident.
Do not press the panel forcefully.
Do not scratch the panel with fi ngernails or any hard
objects.
Do not bump the front panel.
Failure to observe the above may damage or break
the glass on the surface of the touch panel.
