WARNING
The use of optical instruments with this product will
increase eye hazard.
Repair handling should take place as much as possible
with a disc loaded inside the player.
WARNING LOCATION: Top of the DVDR Mechanism
WARNING: Laser Safety
This product contains a laser beam component. This component may emit invisible, as well as visible radiation, which may
cause eye damage. To protect your eyes and skin from laser radiation, the following precautions must be used during
servicing of the unit.
1) When testing and/or repairing any component within the product, keep your eyes and skin more than 30 cm away from
the laser pick-up unit at all times. Do not stare at the laser beam at any time.
2) Do not attempt to readjust, disassemble or repair the laser pick-up, unless noted elsewhere in this manual.
3) CAUTION: Use of controls, adjustments or performance of procedures other than those specified herein may result in
hazardous radiation exposure.
Laser Emitting conditions:
1) When the Top Cover is removed and the "STANDBY/ON" SW is turned to the "ON" position, the laser component will emit
a beam for several seconds to detect if a disc is present. During this time (5 - 10 sec.) the laser may radiate through the
lens of the laser pick-up unit. Do not attempt any servicing during this period!
If no disc is detected, the laser will stop emitting the beam. When a disc is loaded, you will not be exposed to any laser
emissions.
2) The laser power level can be adjusted with the VR on the pick-up PWB. However, this level has been set by the factory prior to
shipping from the factory. Do not adjust this laser level control unless instruction is provided elsewhere in this manual.
Adjustment of this control can increase the laser emission level from the device.

■LOCALE MANAGEMENT INFORMATION
Locale Management Information : This DVD recorder is designed and manufactured to respond to the Locale Management
Information that is recorded on the DVDR disc. If the Locale number described on the DVDR disc does not correspond to the
Locale number of this DVD recorder, this DVD recorder cannot play this disc.
This product incorporates copyright protection
technology that is protected by method claims of
certain U.S. patents and other intellectual
property rights owned by Macrovision
Corporation and other rights owners. Use of this
copyright protection technology must be
authorized by Macrovision Corporation, and is
intended for home and other limited viewing uses
only unless otherwise authorized by Macrovision

■PREVENTION OF ELECTRO STATIC DISCHARGE
The laser diode in the DVDR mechanism may be damaged due to static electricity from clothes or the human body. Use
caution to prevent electrostatic damage when servicing or handling the DVDR mechanism.
1. Grounding for electrostatic damage prevention
Some devices, such as the DVD recorder, use an optical pickup (laser diode) that will be damaged by static electricity in the
working environment. Only attempt service after ensuring that all grounding procedures have been completed.
1. Worktable grounding
Put a grounded conductive material (sheet) or iron sheet on the area where the optical pickup is placed.
2. Human body grounding
Use an anti-static wrist strap to discharge the static electricity from your body.
1M Conductive material
(sheet) or iron sheet
Anti-static wrist strap
2. Handling Precautions for DVDR mechanism
1. Handle the DVDR mechanism gently, as it is an extremely high-precision assembly.
2. The flexible cable lines may break if an excessive force is applied to it. Use caution when handling the cable.
3. The semi-fixed resistor for laser power adjustment should not be adjusted. Do not turn the resistor.
Warning for power supply
The primary side of the power supply carries live mains voltage when the player is connected to the mains even
when the player is switched off !
This primary area is not shielded so it is possible to touch copper tracks and/or components when servicing the player.
Service personnel have to take precautions to prevent touching this area or components in this area .
The primary side of the power supply has been indicated with a lightening stroke and a stripe-marked print on the printed
wiring board

During the test, the following display
is shown: the counter counts down

To exit DEALER SCRIPT, unplug the power cord
Due to the complexity of the DVD recorder, the time to find
a defect in the recorder can become long. To reduce this
time, the recorder has been equipped with Diagnostic and
Service software (DS). The DS offers functionality to
diagnose the DVDR hardware and tests the following:
•Interconnections between components
•Accessibility of components
•Functionality of the audio and video paths
This functionality can be accessed via several interfaces:
1. End user/Dealer script interface
2. Player script interface
1. End User/Dealer Script Interface
1.1 Description
The End user/Dealer script interface gives a diagnosis on
a stand alone DVD recorder; no other equipment is
needed. During this mode, a number of hardware tests
(nuclei) are automatically executed to check if the recorder
is faulty. The diagnosis is simply a "fail" or "pass"
message. If the message "FAIL" appears on the display,
there is apparently a failure in the recorder. If the message
"PASS" appears, the nuclei in this mode have been
executed successfully. There can be still a failure in the
recorder because the nuclei in this mode don't cover the
complete functionality of the recorder.

2.3 Command Mode Interface
Set-Up Physical Interface Components
Hardware required:
•Service PC
•one free COM port on the Service PC
•special cable to connect DVD recorder to Service PC
The service PC must have a terminal emulation program
(e.g. Hyperterminal) installed and must have a free COM
port (e.g. COM1). Activate the terminal emulation program
and check that the port settings for the free COM port are:
19200 bps, 8 data bits, no parity, 1 stop bit and no flow
control. The free COM port must be connected via a
special cable to the RS232 port of the DVD recorder. This
special cable will also connect the test pin, which is
available on the connector, to ground (i.e. activate test
pin).
Code number of PC interface cable: 3122 785 90017
(AAX57390)
Activation Digital Board Chrysalis
1. Pull the mains cord from the recorder and reconnect it
again (reboot).
2. The next welcome message will appear on the PC:
Welcome screen D&S program
Fig. 3
Now, the prompt 'DS:>' will appear. The diagnostic
software is now ready to receive commands. The
commands that can be given are the numbers of the
nuclei. If you see above shown screen, continue with
paragraph 'Nuclei Codes'.
3. It is possible that the next message will appear when
starting the DVD+RW for the first time
Error message D&S program
Fig. 4
In this case, the boot EEPROM of the Chrysalis Digital
Board does not contain the required string with the
hardware information. To update the Digital Board with the
correct string, nucleus 1226 must be executed.
Before doing so, one must generate this string. In order to
generate the correct parameters, an MS Windows utility,
called "dbstring.exe", is available (contact your Philips
regional service support for this). For a detailed
description, see next section 'String Generation'.
String Generation
4. Browse to the directory with the Diagnostics software
(e.g. type 'cd c:\ds\'), and execute the 'dbstring.exe'
application.

7. Confirm the choice by typing 'y' followed by 'Enter'. Now
press any key to return to the prompt.
8. A text file called 'DBSTRING.TXT' is created, which
contains the parameters that are necessary for nucleus
1226. Copy this string from the text-file (e.g. by using
'Ctrl C').
