Precautions (ISO Connector)

¡Wiring for the power connector conforms to the arrangement of standard ISO connectors. ¡In case of some car types, the arrangement of connector may differ from the standard ISO

as shown in Table 1, even though ISO connectors are adopted.

¡Make sure the ISO connector arrangement in your car side is as the same as the stan-

dard ISO. (Table 1, Fig. 1)

¡In case of arrangement for Car type A or B, change connections of the red/yellow leads at

the re-connectable joint (C) as shown in Fig.1.

Panasonic welcomes you to their constantly growing family of electronic products owners.

We endeavor to give you the advantages of precise electronic and mechanical engineering, manufactured with carefully selected components, and assembled by people who are proud of the reputation their work has built for our company . We know this product will bring you many hours of enjoyment, and after you discover the quality , value and reliability we have built into it, you too will be proud to be a member of our family.

Precautions

Volume Level

For your driving safety, keep the volume level low enough to be aware of road and traffic conditions.

Car Washing

To avoid electrical shorts which may cause fire, or other damage, do not expose this product (including the speakers and MDs) to water or excessive moisture.

Car Ventilation

If your car is parked for several hours in direct sunlight, the temperature inside the car may become very high. It is advisable to drive the car and give the interior a chance to cool down before switching the unit on.

Power Supply

This product is designed to be used in a car having 12-volt negative ground battery system.

Disc Mechanism

Do not insert coins or any small objects. Keep screwdrivers and other metallic objects away from the disc mechanism and disc.

Service

This product is made of precision parts. Do not attempt to disassemble or adjust any parts. For repair, please consult your nearest authorized Panasonic Service Center.

About Preset Memory

The preset memory is cleared to return to the original factory setting when the power connector or battery is disconnected.

Laser Products

Caution: This product utilizes a laser. Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

Laser products:

Wave Length 790 nm Laser Power No hazardous radiation is

emitted with safety protection.

Do not take apart this unit or attempt to make any changes yourself.

This unit is a very intricate device that uses a laser pickup to retrieve information from the surface of Mini discs. The laser is carefully shielded so that its rays remain inside the cabinet. Therefore, never try to disassemble the player or alter any of its parts since you may be exposed to laser rays and dangerous voltages.

RDS (Radio Data System) Reception

Note: When you’re in AF ON mode, auto preset memory only works for RDS station. When in TA O N

mode, it only works for TP stations.

To make auto preset for ordinary stations, cancel AF mode and

change to TA off in advance.

Many FM stations are broadcasting added data compatible with RDS. This radio set offers convenient functions using such data.

AF (Alternative Frequency)r

When receiving condition becomes poor, an RDS station with the same program will be automatically selected.

EON (Enhanced Other Networks)r

When EON data is received, the EON indicator lights and the TA and AF functions are expanded.

TA: Traffic information from not only the station now

tuned in to but also other network stations can be received.

AF: The frequency list of the RDS stations preset

by received EON data is updated.

PS (Program Service Name)r

When an RDS station is received, the name of that station automatically displays instead of the frequency. When [

•

](DISP/CT) is pressed during PS

display, the frequency appears on the display for 3 seconds, then PS display returns.

PI (Program Identification)r

If a preset RDS station is poor in receiving condition when it is selected, the automatic seek (PI Seek) starts to seek the same program and tune in to it.

PTY (Program Type)r

Program type identification signal

Example : News, rock, classical music, etc.

TA (Traffic Announcement)

When an FM station that periodically provides the latest traffic information is received, the TP indicator lights. If TA ON is set, FM traffic information automatically interrupts your listening to a MD or CD changer until it ends, then you will listen again to whatever you have been listening to.

REG (Region)

The AF, Best Station Research, PI Seek functions will be as follows: REG ON : The frequency changes only with the same regional program. This function is mainly used

while driving in the same area, for example, in a city.

REG OFF: The frequency changes even with a different regional program if the station is in the same net-

work. The broadcast may be different depending on the case. This function is mainly used when driving far from one region to another.

What Provides EON Capabilities

EON lets the radio set take advantage of RDS information much more than before. It constantly updates the AF list of all presets, including the station currently tuned in to. So, even if you change preset far from home, you will be able to receive the same station at an alternative frequency, or another station serving the same program if any. EON also keeps track of locally available TP stations for quick reception.

Best Station Research

If a preset RDS station is in poor condition of reception when you try to tune in to it, the best frequency is selected from the AF list of that station.

RDS Reception

Press [AF] when receiving a station in the FM1, FM2 or FM3 band.

¡

AF ON/OFF can be set common to all FM bands.

¡Select AF ON if you wish to use the AF network of an RDS station.

Best station research is activated at the same time.

¡Select AF OFF if the AF network of an RDS station is not necessary.

Notes:

1. Default mode is AF1.

2. AF1 has a low level of AF operating sensitivity in urban areas. Therefore, AF does not frequently operate even when sensitivity is temporarily lowered between skyscrapers, for example.

3. AF2 is for suburban areas with a higher level of sensitivity than AF1.

RDS seek tuning (PI seek)

The PI seek function may be used if an RDS station selected from the memory is poor in receiving condition. Press the preset button again for the station now tuned in to.

PI Seek: If Best Station Research fails in selecting the best station,

the PI seek function operates to automatically tune in to the same program.

Changing Display

Press [•](DISP/CT) to change the display as follows.

(Frequency display continues for only 3 seconds, returning to PS display after that.)

Clock Time (CT) System

The CT (24-hour) system may not properly operate in areas where RDS CT service is not available.

Once CT service is received, the CT system keeps operating. “NO CT” appears on the display in areas where no CT service is available.

For Seek Tuning, RDS Station Preset, Tuning in a RDS preset station, and Auto RDS Station Preset, please refer to Radio Basics (pages 16 to 18).

Note: If you wish to stay with the same program, keep REG ON. In

REG OFF mode, there is a higher possibility of returning to an AF station in better receiving condition. The relationship of the PI seek function with REG ON and REG OFF is as described above.

Region (REG) Switching

Press and hold [AF](REG) for more than 2 seconds in AF mode to alternately select between REG ON and REG OFF.
