What are "regional codes"?
Motion picture studios want to control the home release of movies in different countries because theater releases arenít
simultaneous (a movie may come out on DVD in the US when itís just hitting screens in Europe). Therefore they have
required that the DVD standard include codes which can be used to lock out the playback of certain discs in certain geographical regions. Players sold in each region will have that regionís code built into the player. The player will refuse to play
these "region coded" discs which are not allowed in the region. However, regional codes are entirely optional. Discs without
codes will play on any player in any country. Some studios have already announced that only their new releases will have
regional codes. There are six regions:
1. United States and Canada
2. Europe and Japan
3. Far East (except Japan & China)
4. South America and Oceania
5. Africa and the Middle East
6. China (except Hong Kong)

DVD INFORMATION
Below is a glossary of the new terms related to DVD.
Title:
A disc may have more than one story/movie on it, so each
story/movie is called a “title”.
For example, if there are 2 movies on the disc, they are
separated into Title 1 and Title 2.
Chapter:
A title may also be separated into chapters.
For example, a movie (title) may be separated into 3 scenes
(chapters).
Safety Lock
The safety look prevents children from playing discs. When
the Safety Lock is set, discs can not be played back.
Cancelling Safety Lock
Press the CLEAR button and hold for 10 seconds while the
player is stopped.

Caution
T o protect the laser diode from damage caused by high voltage
static electricity, a laser diode protection circuit has to be
shorted before disconnecting the flexible cable (P200
connector on the MECHANISM PCB). It is recommended that
you put solder on the top of the soldering iron as shown in Fig.
3-5 then short the circuit at once. When you replace the
TRA VERSE MECHA., be sure to connect the P200 connector
before removing the solder at the shorted parts.

2. Play back the swayed DVD disc and press the F.F button
repeatedly until the pickup block reaches the outermost
position of its movable range. Next, press the P AUSE button.
3. Set the oscilloscope to the DC input mode and connect it to
the TP201 (HOT) and the TP102 (D.GND) on the MAIN
PCB.
4. Adjust the a screw and b screw alternately so that the AC
and DC level of the waveform is minimum. (DC level should
be less than 1.8 V, AC component should be minimum.)
2. Set the oscilloscope to the DC input mode and connect it to
the TP201 (HOT) and the TP102 (D.GND) on the MAIN
PCB.
3. Adjust the VR202 so that the DC level is minimum. (The DC
level should be less than 1.8 V)
9-3. CD TRACKING BALANCE
1. Set the VR1 10 at its center position prior to the adjustment.
2. Connect an oscilloscope to the TP150 (TE) on the MAIN
PCB.
3. Play back an ordinary CD-disc and then set it to the P AUSE
mode. If the play mode does not be engage, turn the VR110
at ±15 degrees. If the play mode does still not be engage
even when the VR110 is turned at ±15 degrees, turn the
VR110 at ± 30 degrees and try it again.
4. Observe the waveform and adjust it so that the level A of
the waveform is the same as level B.
