This pictograph intends to alert you to the presence of important operating instructions. Failure to heed the Warning instructions may result in severe injury or death.

Warning

Observe the following warnings when using the unit.
Use the proper power supply. This product is designed for operation with a negative grounded 12 V DC battery system. Never operate this product with other battery system, especially a 24 V DC battery system. Do not disassemble or modify the unit. Do not disassemble, modify the unit or attempt to repair the product yourself. If the product needs to be repaired, consult your dealer or an authorised Panasonic Servicenter. Do not use the unit when it is out of order. If the unit is out of order (no power, no sound) or in an abnormal state (has foreign objects in it, is exposed to water, is smoking, or smells), turn it off immediately and consult your dealer. Refer fuse replacement to qualied service personnel. When the fuse blows out, eliminate the cause and have it replaced with the fuse prescribed for this unit by a qualied service engineer. Incorrect replacement of the fuse may lead to smoke, re, and damage to the product. When replacing one fuse which has blown, replace other fuses at the same time. In some cases, fuses may deteriorate without failing. Using different substitutes or fuses with higher ratings, or connecting the unit directly without a fuse, could cause re or damage to the unit. If the replacement fuse fails, contact your nearest Panasonic Servicenter for service.
Observe the following warnings when installing.
Disconnect the lead from the negative () battery terminal before installation. Wiring and installation with the negative () battery terminal connected may cause electrical shock and injury due to a short circuit. Some cars equipped with the electrical safety system have specic procedures of battery terminal disconnection. FAILURE TO FOLLOW THE PROCEDURE MAY LEAD TO THE UNINTENDED ACTIVATION OF THE ELECTRICAL SAFETY SYSTEM RESULTING IN DAMAGE TO THE VEHICLE AND PERSONAL INJURY OR DEATH. Never use safety-related components for installation, grounding, and other such functions. Do not use safety-related vehicle components (fuel tank, brake, suspension, steering wheel, pedals airbags, etc.) for wiring or xing the product or its accessories. Check for piping, gasoline tank, electric wiring, and other items before installing the product. If you need to open a hole in the vehicle chassis to attach or wire the product, rst check where the wire harness, gasoline tank, and electric wiring are located. Then open the hole from outside if possible. After installation and wiring, you should check the normal operation of other electrical equipment. The continuation of their using in abnormal conditions may cause re, electrical shock or a trafc accident. In the case of installation to an airbag-equipped car, conrm warnings and cautions of the vehicle manufacturer before installation. Make sure the leads do not interfere with driving or getting in and out of the vehicle. Failure to heed this caution may result in an accident and/or injury.

Make sure to use the ground lead (black) separately sold and specially designed for car audio system, and to connect it to the metal portion of the car chassis. Wire the battery lead (yellow), the ground lead (black), the speaker cords, and this unit with as much distance as possible from the antenna, the antenna cords and the car stereo (car radio). If the ground wire is common to both left/right and front/rear speaker wirings, this unit cannot be used. Always use the independent lead wire for the speakers to be used. In this case, redo the wiring. Caution for the speaker cord (option): The speaker cords and the power amplier unit should be kept away from the antenna and antenna extension cord. Do not directly ground the speaker cords; do not share the negative leads of multiple speakers. When using the RCA cords, keep away from the speaker cords. Caution for the speaker (option): Use speakers with a suitable maximum input. In case of 4-channel/3-channel connection <CY-PA4003U>: Use speakers with the impedance of 28. In case of 2-channel/stereo connection: Use speakers with the impedance of 48.

Panasonic shall not be liable for any accidents arising out of neglect of checking the unit or your own repair after your checking. Never take measures especially those other than indicated by italic letters in Possible solution described below because those are too dangerous for users to handle themselves.
Do not use the unit in abnormal condition, for example, without sound, or with smoke or foul smell, which can cause ignition or electric shock. Immediately stop using the unit and consult your dealer. Never try to repair the unit by yourself because it is dangerous to do so.
Problem No sound available. (continued)
Possible cause Possible solution There is an electromagnetic-wave generator such as a cellular phone near the unit or its electrical lines. Keep the electromagnetic-wave generator such as a cellular phone away from the unit and the wiring of the unit. If noise cannot be eliminated due to the wiring harness of the car, consult your dealer. Fuse blows out. Eliminate the cause of fuse blowout and replace the fuse with new one. Consult your dealer.
Bad sound quality (Distorted sound) Noise
The bass is too much enhanced. Set the bass boost appropriately.
Problem No sound available.
Possible cause Possible solution The power cord (battery, power and ground) is connected in the wrong way. Check the wiring. The contact of the ground lead is poor. Make sure that the ground lead is connected to an unpainted part of the chassis securely. The speaker cord is short-circuited. Check the speaker cord, and replace the fuse. The speaker received damage because of too small input capacity. Obtain the right speaker allowed to connect this unit, and replace the fuse. (page 34) The speaker cord is not properly connected.

Troubleshooting

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

Replacing the Fuse

Use fuses of the same specied rating. CY-PA4003U: 35 A2 CY-PA2003U: 25 A3 CY-PAD1003U: 25 A3 When replacing one fuse which has blown, replace other fuses at the same time. In some cases, fuses may deteriorate without failing. Using different substitutes or fuses with higher ratings, or connecting the unit directly without a fuse, could cause re or damage to the unit.
