Maintenance
Replacing the Fuse
Your product is designed and manufactured to ensure a minimum of maintenance. Use a dry, a soft
cloth for routine exterior cleaning. Never use benzine, thinner or other solvents.
Use fuses of the same specified rating (15 A).
Using different substitutes or fuses with higher ratings, or connecting the unit directly without a fuse,
could cause fire or damage to the unit.
If the replacement fuse fails, contact your nearest
Panasonic service station for service.
Product Servicing
If the suggestions in the charts do not solve the
problem, we recommend that you take it to your
nearest authorized Panasonic service station. The
product should be serviced only by a qualified technician.
Do not leave discs on the following places:
≥ Direct sunlight
≥ Near car heaters
≥ Dirty, dusty and damp areas
≥ Seats and dashboards
Disc cleaning
Use a dry, soft cloth to wipe from the center outward.
<Right>
<Wrong>
Do not attach any seals or labels to your discs.
Do not write on the disc label in a heavy pen or
ballpoint pen stroke.

could cause serious damage.
Before you begin installation, look for the items
which are packed with your unit.

tape
Side-cut

❐ Overview
This product should be installed by a professional.
However, if you plan to install this product yourself,
your first step is to decide where to install it. The instructions in these pages will guide you through the
remaining steps:
(Please refer to the “WARNING” statement
above.)
≥ Identify and label the car wires.
≥ Connect the car wires to the wires of the power
connector.
≥ Install the unit in the dashboard.
≥ Check the operation of the unit.
30
CQ-DF203W
The first step in installation is to identify all the car
wires you’ll use when hooking up your sound system.
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 the stereo
unit until you have made all connections. If there
are no plastic caps on the stereo 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 find 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 find the fuse port for radio
(RADIO), accessory (ACC), or ignition (IGN).

Battery Lead
If your stereo 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, memory storage, or other function.)
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.
E
N
G
L
I
S
H
If your car is not wired for an audio unit:
Go to the fuse block and find the fuse port for the
battery, usually marked BAT.
22
Speakers
Identify the car speaker leads. There are two leads
for each speaker which are usually color coded.
A handy way to identify the speaker leads and the
speaker they are connected with 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 one of the speakers 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.
Antenna Motor
If your car is equipped with an automatic power antenna, identify the car motor antenna lead by connecting one bulb tester lead to the car battery lead
and touching the remaining exposed wires from the
cut radio connector plug one at a time. You will
hear the antenna motor activate when you touch the
correct wire.
Antenna
The antenna lead is a thick, black wire with a metal
plug at the end.
❐ Connect All Leads
Now that you have identified all the wires in the car,
you are ready to begin connecting them to the
stereo unit wires. The wiring diagram (page 36)
shows the proper connections and color coding of
the leads.
We strongly recommend that you test the unit before making a final installation.
You can set the unit on the floor 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
(page 36) for the proper hookups. Follow the diagram carefully to avoid damaging the speakers and
the stereo unit.
The speakers used must be able to handle more
than 50 W of audio power. If using an optional
audio amplifier, the speakers should be able to handle the maximum amplifier 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 stereo unit damage.
Motor Antenna
Connect the car motor antenna lead to the dark blue
motor antenna relay control lead.
(Do not confuse the antenna lead with blue/white
stripe lead for a power amplifier.)
Battery
Connect the yellow battery lead to the correct radio
wire or to the battery fuse port on the fuse block.
Antenna
Connect the antenna by plugging the antenna lead
into the antenna receptacle.
Equipment
Connect any optional equipment such as an amplifier, according to the instructions furnished with the
equipment. Leave about 30 cm of distance between
the speaker leads/amplifier unit and the antenna/antenna extension cord. 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 the stereo unit functions properly with all these
connections made, disconnect the wires and proceed to the final installation.
23
❐ 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 the stereo unit into the mounting
collar.
Congratulations! After making a few final checks,
you’re ready to enjoy your new auto stereo system.

❐ Final Checks
❐ Installation Procedures
1. Make sure that all wires are properly connected
and insulated.
2. Make sure that the stereo unit is securely held in
the mounting collar.
3. Turn on the ignition to check the unit for proper
operation.
First complete the electrical connections, and then
check them for correctness. (page 36)
If you have difficulties, consult your nearest authorized professional installer for assistance.
❐ Preparation
≥ We strongly recommend that you wear gloves
for installation work to protect yourself from
injuries.
≥ When bending the mounting tabs of the
mounting collar with a screwdriver, be careful
not to injure your hands and fingers.
≥ Disconnect the cable from the negative - battery
terminal (see caution below).
≥ Unit should be installed in a horizontal position
with the front end up at a convenient angle, but
not more than 30o.
