Player Zones
For the purpose of distribution of DVD Discs, the world has been separated into 6
zones. The zone your unit is intended for is indicated on the Zone Label. This should
be the same as the label on discs available in your region. If you have any difficulties in
playing a disc, make sure that the disc is for the same zone as your player.
Region 1
Anti-copy Disc Protection
Some DVD discs have anti-copying devices.
With these discs the playback on a Television will give the highest quality picture, however you will not be able to
record this signal on a VCR.
Installation
Install your unit on a stable flat surface. There must be sufficient room in front of the unit for the drawer to be
opened and the unit should be positioned so that it can see the remote control.
Do not expose your unit to extremes of temperature or humidity. Avoid standing it on a hot surface such as on
top of other hot running equipment and ensure that there is adequate ventilation to the unit.
* Caution : Do not install this equipment in confined space such as a book case or similar unit!
DVD Discs
There are several types of DVD Disc.
Single sided discs. They play for approximately 2 HOURS
Single sided two layer discs. They play for approximately 4 HOURS
Double sided discs. They play for approximately 4 HOURS
Double sided with 2 layers on both sides. They play for approximately 8 HOURS
DVD discs have Titles and Chapters. There can be several Titles on one disc and each Title can contain several
Chapters. Titles and Chapters are numbered, e.g. Title 1, Title 2 etc. & Chapter 1,2,3 etc.
Usually Title one will show the disc publisher and studio
logos. The next Title will be the film. Other Titles
contain trailers for other films, production notes, or
alternative endings for the film. There are many
possibilities with Digital Versatile Disc. Chapters within
the main Title allow you to search quickly for a specific
point on the disc. Many discs have a Chapter Menu
sometimes called Scene Index or Scene Menu that
displays the first shot from each Chapter, which allows
you to select a shot and play the disc from that point
onwards. DVD discs can be PAL or NTSC. This player
can play both types (if the player zone is correct).
DVD discs allow up to 8 Languages and 32 subtitles on a single disc. You can select and change the language
and subtitle to suit yourself and play the whole disc or just part of it and view it from different angles.
Cleaning DVD Discs
Picture freezing & sound skipping or repeating can occur if the disc inside the player is dirty.
• When a disc becomes dirty, clean it with a cleaning cloth. Wipe the disc from the center out.
• Do not wipe in a circular motion. Circular scratches can cause picture distortion or render the disc
unplayable.
CAUTION - Do not use solvents, commercially viable cleaners, or
antistatic spray intended for analog discs.
