Cleaning the pickup lens
The DVD recorder’s lens should not become dirty in
normal use, but if for some reason it should malfunction
due to dust or dirt, consult your nearest Pioneer-
authorized service center. Although lens cleaners for CD
players are commercially available, we do not re-
commend using them since some may damage the lens.
Condensation
Condensation may form inside the recorder if it is
brought into a warm room from outside, or if the
temperature of the room rises quickly. Although the
condensation won’t damage the recorder, it may
temporarily impair its performance. For this reason you
should leave it to adjust to the warmer temperature for
about an hour before switching on and using.
Hints on installation
We want you to enjoy using this unit for years to come, so
please bear in mind the following points when choosing
a suitable location for it:
Do...
Use in a well-ventilated room.
Place on a solid, flat, level surface, such as a table,
shelf or stereo rack.
Don’t...
Use in a place exposed to high temperatures or
humidity, including near radiators and other heat-
generating appliances.
Place on a window sill or other place where the
recorder will be exposed to direct sunlight.
Use in a dusty or damp environment or in a room
where it will be exposed to excessive cigarette smoke.
Place directly on top of an amplifier, or other
component in your stereo system that becomes hot in
use.
Use near a television or monitor as you may
experience interference—especially if the television uses
an indoor antenna.
Use in a kitchen or other room where the recorder
may be exposed to smoke or steam.
Use on a thick rug or carpet, or cover with cloth—this
may prevent proper cooling of the unit.
Place on an unstable surface, or one that is not large
enough to support all four of the unit’s feet.
Moving the recorder
If you need to move the recorder, first remove the disc, if
there’s one loaded, and close the disc tray. Next, press
STANDBY/ON
to switch the power to standby, checking
that the
POWER OFF
indication in the display goes off.
Wait at least two minutes. Lastly, disconnect the power
cord. Never lift or move the unit during playback or
recording—discs rotate at a high speed and may be
damaged.
Glossary
Analog audio
An electrical signal that directly represents sound.
Compare this to digital audio which can be an electrical
signal, but is an indirect representation of sound. See

Digital audio
.
Aspect ratio
The width of a TV screen relative to its height.
Conventional TVs are 4:3 (in other words, the screen is
almost square); widescreen models are 16:9 (the screen
is almost twice as wide as it is high).
Chapter
Just as a book is split up into several chapters, a title on
the HDD/a DVD disc is usually divided into chapters. See

Title
.
Digital audio
An indirect representation of sound by numbers. During
recording, the sound is measured at discrete intervals
(44,100 times a second for CD audio) by an analog-to-
digital converter, generating a stream of numbers. On
playback, a digital-to-analog converter generates an
analog signal based on these numbers. See also

system is used in many movie theaters around the world.
