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.

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.

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.

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 also Digital audio.

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:

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).

Do...

Use in a well-ventilated room.

Place on a solid, flat, level surface, such as a table, shelf or stereo rack.

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 also Title.

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.

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 Sampling frequency and Analog audio.
