It does not contain warnings or cautions of potential dangers in attempting to install this product. Any attempt to install this product in a motor vehicle by anyone other than qualified installer could cause damage to the electrical system and could result in serious personal injury or death. ❏ Overview This equipment should be installed by a professional. However, if you plan to install this unit 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 "WARNING" statement above). Identify and label the vehicle wires Connect the vehicle wires to the wires of the power connector Install the unit in the dash Check the operation of the unit If you do encounter problems, please consult your nearest authorized dealer. Caution: This unit will operate with a 12 volt 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 following items included in the packing with your unit. Warranty Card ...... Fill this out promptly Panasonic Servicenter for service Directory ...... Keep this for future reference in case the unit needs servicing Installation Hardware ...... Needed for in-dash installation 19 ❏ Installation Hardware No. Item Diagram Qty Mounting Collar 1 Plain Washer (5 mmφ) 2 Spring Washer (5 mmφ) 2 Hex. Nut (5 mmφ) 2 Rear Support Strap 1 Hex. Bolt (5 mmφ × 25 mm) 1 Toothed Lock Washer (5 mmφ) 1 Power Connector 1 Removal Tool (U-shaped) 2 Antenna Connector 1 ❏ Required Tools You'll need a screwdriver, a 1.5 volt AA battery and the following: 12 V DC ELECTRICAL SIDE-CUT TEST BULB TAPE PLIERS 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. ❏ Dashboard Specifications THICKNESS MIN. 3/16" (4.75 mm) MAX. 7/32" (5.56 mm) 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 vehicle power lead. 2-3/32" (53 mm) 7-5/32" (182mm) ❏ Identify All Leads The first step in installation is to identify all the vehicle 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 vehicle has a radio or is pre-wired for one: If your vehicle 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 vehicle's batter y 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 vehicle has a radio or is pre-wired for one: With the ignition and headlights off, identify the vehicle 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 vehicle 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 vehicle speaker leads. There will be two leads for each speaker, usually color coded. 20 Installation Guide (continued) A handy way to identify the speaker leads and the speaker they connect with is to test the leads using a 1.5 volt 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. Speakers Connect the speaker wires. See the wiring diagram below for the proper hookups. Follow the diagram carefully to avoid damaging the speakers and the stereo unit. The speaker used must be able to handle more than 37 watts of audio power. If using an optional audio power, the speakers should be able to handle the maximum amplifier output power. Speakers with low input ratings can be damaged. Antenna The antenna lead is a thick, black wire with a metal plug at the end. Speaker impedance should measure 4 - 8 ohms, which is typically marked on most speakers. Lower or higher impedance speakers will affect output and can cause both speaker and stereo unit damage. ❏ Connect All Leads Caution: Never ground the speaker cords. For example, do not use a chassis ground system or a three-wire speaker common system. Each speaker must be connected separately using parallel insulated wires. If in doubt about how your car's speakers are wired, please consult with your nearest professional installer. Now that you have identified all the wires in the vehicle, you’re ready to begin connecting them to the stereo unit wires. The connection diagram on Page 26, 27 show 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 vehicle chassis. CORRECT No Common Ground L + – R + – INCORRECT Common Chassis Ground L + – R + – INCORRECT Speaker Common (common earth lead) 21 L + – R + – 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 amplifier, according to the instructions furnished with the equipment. Keep about 12 inches (30 cm) of distance between the speaker cords/amplifier unit and the antenna/antenna extension cord. Read the operating and installation instructions for any equipment you will connect to this unit. Accessory (ACC) Power Connect the red power lead to the correct vehicle radio wire or to the appropriate fuse port on the fuse block. ❏ 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 won't 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. If the stereo unit functions properly with all these connections made, disconnect the wires and proceed to the final installation. 22 Installation Guide (continued) ❏ Installation Procedures When bending the mounting tab of the mounting collar with a screwdriver, be careful not to injure your hands and fingers. We strongly recommend you to wear gloves for installation work to protect yourself from injuries. Note: Disconnect the cable from the negative (–) battery terminal. 1. Secure the Mounting Collar . Insert Mounting Collar into the vehicle's dashboard, and bend mounting tabs out with a screwdriver. Mounting Tab Dashboard 1 Mounting Collar Screwdriver 2.
