Speaker Connections

Caution: Please follow the instructions given below. Failure to do so will cause damage to the unit and speakers.

• Use ungrounded speaker only.
• The maximum speaker input should be 50 W or more. (If used with the optional power amplifier, the speaker input should be higher than the maximum amplifier output.)
  The speaker impedance should be 4-8Ω.
• This unit uses the BTCL circuit, so each speaker should be connected separately using parallel vinyl insulated cords.
• The speaker cords and the power amplifier unit should be kept away (about 30 cm apart) from the antenna and antenna extension cord.

• Never connect the speaker cord to the body of the car.

• Do not use a 3-wire type speaker system having a common earth lead.

• Do not connect more than one speaker to one set of speaker leads.

Fuse

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 fuse replacement fails, contact your nearest authorized Panasonic Service Center.

Product Servicing

If the suggestions in the charts do not solve the problem, we recommend that you take it to your nearest authorized Panasonic Servocenter. The product should be serviced only by a qualified technician.

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:

(Pleaseseretothe"WARNINGstatementabove.)

• 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.

If you encounter problems, please consult your nearest professional installer.

Caution:

• This unit operates with a 12 V DC negative ground auto battery system only. Do not attempt to use it in any other system. Doing so could cause serious damage.

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

Required Tools

You'll need a screwdriver, a 1.5 V AA battery, and the following:

12VDC

Test bulb

Electrical tape Side-cut

pilers

Identify All Leads

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 transmitter plug.

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.

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

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 ( 一 page 28) 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 load 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.

Installation Guide (Continued)

Speakers

Connect the speaker wires. See the wiring diagram ( page 28) 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 impedances 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.

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 12^ (30 cm) of distance between the speaker leads/amplifier unit and the antenna/anlenna 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.

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

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.

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 cautions below).
• Unit should be installed in a horizontal position with the front end up at a convenient angle, but not more than 30^ .

Caution: Do not disconnect the battery terminals of a car with a trip or navigational computer since all user settings stored in memory will be lost. Instead take extra care with installing the unit to prevent shorts.

Dashboard Installation

Installation Opening

This unit can be installed in any dashboard having an opening as shown above. The dashboard should be 1 / 2 (4.75 mm) - 1 / 2 (5.56 mm) thick in order to be able to support the unit.

CQ-R253U

Cautions:

• We strongly recommend that you wear gloves for installation work to protect yourself from injuries.
