Placing the sub woofer (MHC-GX40
only)
Since the human ear cannot detect the direction
and position where the bass sound being
reproduced by a woofer (below 150 Hz) comes
from, you can place the woofer wherever you
like in your room. To obtain a better bass
reproduction, we recommend you to place the
woofer on a solid floor where the resonance is
unlikely to occur.
Notes
• Always place the woofer vertically, keeping a few
centimeters from away the wall.
• If the woofer is placed in the center of a room, the
bass could be extremely weakened. This is due to
the influence of the standing wave of the room. If
this happened, move the woofer away from the
center of a room or eliminate the cause of the
standing wave, by placing a bookshelf on the wall,
etc.
When carrying this system

Using the Radio Data System (RDS)
(MHC-RG110/RG33/RG22, MHC-RL3,
European model only)
What is the Radio Data System?
Radio Data System (RDS) is a broadcasting
service that allows radio stations to send
additional information along with the regular
program signal. This tuner offers convenient
RDS features like station name display and
location of stations by program type. RDS is
available only on FM stations.*
Note
RDS may not work properly if the station you tuned
in is not transmitting the RDS signal properly or if the
signal is weak.
* Not all FM stations provide RDS service, nor do
they provide the same types of services. If you are
not familiar with the RDS system, check with your
local radio stations for details on RDS services in
your area.
Receiving RDS broadcasts
Simply select a station from the FM band.
When you tune in a station that provides RDS
services, the station name appears in the
display.
To check the RDS information
Each time you press DISPLAY, the display
changes cyclically as follows:
Station name* t Frequency t Program
type* t Clock display t Effect status
* If the RDS broadcast is not received, the station
name and program type may not appear in the

Additional Information
Precautions
On operating voltage
Before operating the system, check that the operating
voltage of your system is identical with the voltage of
your local power supply.
On safety
• The unit is not disconnected from the AC power
source (mains) as long as it is connected to the wall
outlet, even if the unit itself has been turned off.
• Unplug the system from the wall outlet (mains) if it
is not to be used for an extended period of time. To
disconnect the cord (mains lead), pull it out by the
plug. Never pull the cord itself.
• Should any solid object or liquid fall into the
component, unplug the system and have it checked
by qualified personnel before operating it any
further.
• The AC power cord must be changed only at a
qualified service shop.
On placement
• Do not place the system in an inclined position.
• Do not place the system in locations where it is:
— Extremely hot or cold
— Dusty or dirty
— Very humid
— Subject to vibrations
— Subject to direct sunlight.
• Use caution when placing the unit or speakers on
surfaces that have been specially treated (with wax,
oil, polish, etc.) as staining or discoloration of the
surface may result.
On heat build up
• Although the system heats up during operation, this
is not a malfunction.
• Place the system in a location with adequate
ventilation to prevent heat build up in the system.
• If you continuously use this system at a large
volume, the cabinet temperature of the top, side and
bottom rises considerably. To avoid burning
yourself, do not touch the cabinet.
• To prevent a malfunction, do not cover the
ventilation hole for the cooling fan.
On operation
• If the system is brought directly from a cold to a
warm location, or is placed in a very damp room,
moisture may condense on the lens inside the CD
player. Should this occur, the system will not
operate properly. Remove the CD and leave the
system turned on for about an hour until the
moisture evaporates.
• When you move the system, take out any discs.
Notes on CDs
• Before playing, clean the CD with a cleaning cloth.
Wipe the CD from the center out.
• Do not use solvents.
• Do not expose the CD to direct sunlight or heat
sources.
Note on CD-R/CD-RW playback
Discs recorded on CD-R/CD-RW drives may not be
played back because of scratches, dirt, recording
condition or the drive’s characteristics. Besides, the
discs, which are not yet finalized at the end of
recording, cannot be played back.
Music discs encoded with copyright
protection technologies
This product is designed to playback discs that
conform to the Compact Disc (CD) standard.
Recently, various music discs encoded with copyright
protection technologies are marketed by some record
companies. Please be aware that among those discs,
there are some that do not conform to the CD
standard and may not be playable by this product.
Cleaning the cabinet
Use a soft cloth slightly moistened with mild
detergent solution.
To save a tape permanently
To prevent a tape from being accidentally recorded
over, break off the cassette tab from side A or B as
illustrated. If you later want to reuse the tape for
recording, cover the broken tab with adhesive tape.
Tab of side B

Precautions (continued)
Specifications
Before placing a cassette in the tape
deck
Take up any slack in the tape. Otherwise the tape may
get entangled in the parts of the tape deck and become
damaged.
When using a tape longer than 90
minutes
The tape is very elastic. Do not change the tape
operations such as play, stop, and fast-winding
frequently. The tape may get entangled in the tape
deck.
Cleaning the tape heads
Clean the tape heads after every 10 hours of use.
Be sure to clean the tape heads before you start an
important recording or after playing an old tape. Use
a separately sold dry-type or wet-type cleaning
cassette. For details, refer to the instructions of the
cleaning cassette.
Demagnetizing the tape heads
Demagnetize the tape heads and the metal parts that
have contact with the tape every 20 to 30 hours of use
with a separately sold demagnetizing cassette. For
details, refer to the instructions of the demagnetizing
cassette.
