DVD video disc glossary—
DVD video discs: Digital versatile disc that holds video. DVD
video discs have adopted “MPEG2”, one of the world
standards of digital compression technologies. The picture
data is compressed by 1/40 on average and stored. Variable
rate encoded technology in which the volume of data assigned
to the picture is changed depending on the picture format has
also been adopted. Audio data is stored using PCM and Dolby
digital, which enables higher quality of sound. Furthermore,
multi−angle and multi −language features will also help you
enjoy the more advanced technology of DVD video.
Viewer restrictions: This feature limits what can be viewed
in conformity with a level of restrictions of the country. The level
of restrictions varies depending on the DVD video disc. Some
DVD video discs cannot be played at all, or violent scenes are
skipped or replaced with other scenes.
Level 1: DVD video discs for children can be played.
Level 2 − 7: DVD video discs for children and G−rated movie
can be played.
Level 8: All types of the DVD video discs can be played.
Multiangle feature: You can enjoy the same scene at
different angles.
Multilanguage feature: You can select a language of the
subtitle and audio.
Region codes: The region codes are provided on DVD
players and DVD discs. If the DVD video disc does not have
the same region code as the DVD player, you cannot play the
disc on the DVD player. For region codes, see page 329.

Audio system operating hints
NOTICE
To ensure correct audio system operations:
Be careful not to spill beverages over the audio
system.
 Do not put anything other than a cassette tape or disc
into the cassette tape slot or disc slot.
 The use of a cellular phone inside or near the vehicle
may cause a noise from the speakers of the audio
system which you are listening to. However, this
does not indicate a malfunction.
Radio reception
FM broadcasts have a range of about 40 km or 25 miles. When
driving away from a station, you may have to fine −tune your
radio and turn up the volume as the station gets weaker.
Because FM uses a line −of− sight signal, tall buildings or hills
may sometimes block reception. These are all normal
characteristics of FM recept ion and do not indicate any
problem with the radio itself. Caring for your cassette player and tapes
For the best performance for your cassette player and tapes:
Clean the tape head and other parts regularly.

A dirty tape head or tape path can decrease sound quality
and tangle your cassette tapes. The easiest way to clean
them is by using a cleaning tape. (A wet type is
recommended.)
Use high− quality cassettes:
 Low −quality cassette tapes can cause many problems,
including poor sound, inconsistent playing speed, and
constant auto− reversing. They can also get stuck or
tangled in the cassette player.
 Do not use a cassette if it has been damaged or tangled or
if its label is peeling off.
 Do not leave a cassette in the player if you are not listening
to it, especially if it is hot outside.
 Store cassettes in their cases and out of direct sunlight.
 Avoid using cassettes with a total playing time longer than
100 minutes (50 minutes per side). The tape used in these
cassettes is thin and could get stuck or tangled in the
cassette player.

AUDIO
334Caring for your CD player or DVD player, and discs

Your CD player or DVD player is intended for use with 12 cm
(4.7 in.) discs only.
 Extremely high temperature can keep your CD player or
DVD player from working. On hot days, use air conditioning
to cool the vehicle interior before you listen to a disc.
 Bumpy roads or other vibrations may make your CD player
or DVD player skip.
 If moisture gets into your CD player or DVD player, you may
not hear any sound even though the player appears to be
working. Eject all discs from the player and wait until the
player dries.
CAUTION
CD players or DVD players use an invisible laser beam
which could cause hazardous radiation exposure if
directed outside the unit. Be sure to operate the player
correctly.

Correct Wrong
 Handle discs carefully, especially when you set them into
the player. Hold them on the edge and do not bend them.
Avoid getting fingerprints on them, particularly on the shiny
side.
 Dirt, scratches, warping, pin holes, or other disc damage
could cause the player to skip or to repeat a section of a
track. (To see a pin hole, hold the disc up to the light.)
20L039
To clean a disc: Wipe it with a soft, lint −free cloth that has been
dampened with water. Wipe in a straight line from the center
to the edge of the disc (not in a circle). Do not use a
conventional record cleaner or anti −static device.
