Caution:
This product utilizes a laser.
Use of controls or adjustments or perfor-
mance of procedures other than those spec-
ified herein may result in hazardous radia-

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 voitages.

RDS (Radio Data System) Reception
Many FM stations are broadcasting added data compatible with RDS. This radio set offers
convenient functions using such data.
AF (Alternative Frequency)
When receiving condition becomes poor, an RDS
station with the same program will be automatically
selected.
EON (Enhanced Other Networks)
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.
TA (Traffic Announcement)
PS (Program Service Name)
When an RDS station is received, the name of that
station automatically displays instead of the fre-
quency. When [e](DISP/CT) is pressed during PS
display, the frequency appears on the display for 3
seconds, then PS display returns.
PI (Program Identification)
If a preset RDS station is poor in receiving condi-
tion when it is selected, the automatic seek (PI
Seek) starts to seek the same program and tune
in to it.
PTY (Program Type)
Program type identification signal
Example : News, rock, classical music, etc.
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.
Best Station Research
If a preset ADS 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.
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 recep-
tion,
М ная
4
Note: When you're in AF ON mode, auto preset memory only works for RDS station. When in TA ON
| mode, it only works for TP stations. To make auto preset for ordinary stations, cancel AF mode and
| change to TA off in advance.

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.

information. Press [TA] again to switch off.
Volume Setting (Only for TA on mode)
Adjust the volume as desired by pressing [/AVOL] or [VOL] while
receiving Traffic Announcement. (TA)
After volume for Traffic Announcement (TA) is set, the difference
between normal volume and TA volume is automatically stored in the
memory (up to 5 levels) so that next traffic information will be received
at the preceding TA volume which may be higher or lower than normal
volume.
Normal volume can be changed up to 5 levels upward or downward.
If the volume level is over 40 or less than 0, any further change will not
be made.
When receiving a station other than TP station (including EON stations)
A traffic information station is automatically searched for and the radio
automatically stops tuning at the next available TP station.
EON Capabilities:
EON lets the radio take advantage of much more RDS information than
before. It constantly updates the AF lists for all switch presets far from
home, you will receive an alternative frequency for the same station, or
another station carrying the same program, when such exists. EON also
keeps track of locally available TP station.

Speaker Connections
Cautions:
1. Use ungrounded speakers only.
2. The speakers to be used with this unit should be able to handle more than 45W(CQ-MR505N),
40W(CQ-MR303N) of audio power. If an optional amplifier is used, the speakers should be able to han-
dle the maximum output power of the amplifier. Use of speakers with small input ratings can cause dam-
age to the speakers.
3. The speaker impedance should be 4 - 8 Q. If the impedance is too large or too small, it affects the out-
put and may cause damage to the speakers or this unit.
4. Do not use 3-wire type speaker system having a common earth lead. Never connect the speaker cord to
the body of the car. This unit uses the BTCL circuit, so each speaker should be connected separately
using parallel vinyl insulated cords.
5. The speaker cords and the power amplifier unit should be kept away (about 30cm apart) from the anten-
na and antenna extension cord.
6. Follow the connection diagram below carefully. Failure to do so may cause damage to both unit and

Notes on Mini Discs (MD)
E How to Handle MDs
An MD is held in a cartridge to protect the MD from
foreign matter and fingerprints. Great care must be
taken in dealing with an MD in consideration of the
following because a dirty or deformed cartridge can
cause malfunction or sound quality deterioration.
® Never open the shutter of an MD cartridge to
avoid damaging to the cartridge.
e Never insert an MD cartridge if a label on it is
about to come off. Otherwise, the label might be
stuck in the unit and cause a trouble.
* Data MD is not available for the unit. Make sure to
use music MDs.
E How to Store MDs E How to clean MDs

® Avoid leaving MDs at any of the following places.
1. A place exposed to direct sunlight for a long
| time
2. A humid or dusty piace
3. A place exposed to direct heat from heaters.
4. Seats or dashboard in a car
Fuse
Use fuses of the same specified rating (15 A). Using different substitutes or fuses with higher ratings, or con-
meching the unit directly without a fuse, could cause fire or damage to the unit.
E the replacement fuse fails, contact your nearest authorized Panasonic Service Center.
Maintenance
Your product is designed and manufactured to ensure the minimum of maintenance. Use a soft cloth for rou-
ne exterior cleaning. Never use benzine, thinner, or other solvents.
