■ 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
Corporation. Reverse engineering or
disassembly is prohibited.
■ 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.

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.
