About Parental Control

DVD discs have a parental level assigned to the disc. The range of parental controls is from 1 to 8. In general, this range corresponds to established movie rating systems. Movie rating systems may vary depending on the country you live in. Toward the bottom of this page is a small chart showing the rating system and corresponding Parental Control ratings for the USA.

The player can be set in a similar way. If the player's parental level is set to 8 it will play all discs. If the player's parental level is set below 8, only discs with a lower or equal parental level will play.

For example if the player is set to 5, only discs with parental control ratings of 1-5 will play. To play a disc with higher number rating, you must change the player's rating to a higher number.

Consider a disc that is suitable for most audiences, and is rated as level 2 for the most part. However in the middle there are also scenes rated at 5&7(notsuitable for children). Alternative scenes with lower rating are included. The player plays the highest rated scene that the parental setting allows.

A section of the disc can have several different sequences that vary in parental control level. In the above example of a disc with parental control, the player will show a different section depending on the parental control level set in the player's menu.

In this way parents can control the content of films and there is no indication that any censorship has occurred.

About MP3

WhatisMP3?

Corresponding file systems

MP3, whose official name is “MPEG-1Audio Layer 3,” is a compression standard prescribed by the ISO, the International standardization organization and MPEG which is a joint activity institution of the IEC. MP3 files contain compressed audio data. MP3 encoding is capable of compressing audio data at extremely high ratios, reducing the size of music files to as much as one-tenth their original size. This is achieved while still maintaining near CD quality. The MP3 format realizes these high compression ratios by eliminating the sounds that are either inaudible to the human ear or masked by other sounds.

This device supports discs formatted with ISO9660 level 1 or level 2. Under the ISO9660 standard, there are some restrictions to remember: The maximum nested folder depth is 8 (including the root directory). The number of characters for a folder/file names are letters A-Z (all caps), numbers 0-9, and '_' (underscore). This device also can play back discs in Joliet, Romeo, etc., and other standards that conform to ISO9660. However, sometimes the file names, folder names, etc., are not displayed correctly.

In DVD mode, when the disc is playing or in stop mode, press button (27) to enter the setup menu.

1. When the cursor is in the upper part of the menu, use the buttons to move between the different pages.

2. Press button to move the cursor to the setup page below. Then you can use the buttons to move between the different setup options.

4. When the setting is complete, press button (27) to return to normal

When you open the Setup Menu, you will see the System Setup page.

TV SYSTEM is used to select the TV output mode. This player can play discs recorded in either PAL or NTSC formats. Select NTSC format, when the unit is connected to an NTSC TV. Select PAL format, when the unit is connected to a PAL TV.

SETUP

Press or ENTER button to move to the choice list of each setup option and then use the buttons and the ENTER button to change your selection.

* When settings are changed, old settings are overwritten. Make note of the current settings before making changes. If the vehicle’s battery is disconnected, the settings will be cleared and will return to the factory settings when power is next applied.

System Setup

TV SYSTEM

Setup

You can either choose AUTO SELECT, which will sense the type of monitor attached to the output and select NTSC or PAL as needed. If you know the type of monitor, you should choose the type in this menu rather than letting AUTO SELECT do it for you. This is because there may be an undesirable small delay and some flickering of the screen during the AUTO-SELECT process.

As with computer monitor, video screens can “burn in” if a still image is displayed too long on the screen. This unit features a “screen saver” which produces a moving image to avoid burn-in. If SCREEN SAVER is enabled in the Setup menu, after a few minutes of displaying a still image, the player will substitute a moving screen saver image.

TV types can vary based on their aspect ratio. The common monitors fall into one of three categories: 4:3 (PS/Pan and Scan), 4:3 (LB/Letterbox) or 16:9 (Widescreen). Playing a video recorded in one aspect ratio on a monitor with a different ratio can result in some mismatches and undesirable display distortion or cutoffs. Read the following to assist you in setting up the TV type:

Select this when connected to a conventional 4:3 size monitor. The picture will fill the entire TV screen. However, due to the mismatch in aspect ratio, parts of the movie at the extreme left and right sides will not be visible (when playing a 16:9 size movie).

4:3 (Pan and Scan) format is the factory default setting for this product.

The Password system is used in conjunction with the Parental Controls settings to prevent a young person from changing the settings without permission. The factory default password is 0000. If you wish to change this, enter 0000 and when prompted, enter a different 4-digit number.
