■ TO SERVICE PERSONNEL

1. Critical Components Information Components having special characteristics are marked Z and must be replaced with parts having specifications equal to those originally installed.

2. Leakage Current Measurement (For 120V Models Only) When service has been completed, it is imperative to verify that all exposed conductive surfaces are properly insulated from supply circuits.

● Meter impedance should be equivalent to 1500 ohm shunted

by 0.15µF.

WALL OUTLET

● Leakage current must not exceed 0.5mA.

● Be sure to test for leakage with the AC plug in both

polarities.

WARNING: CHEMICAL CONTENT NOTICE!

The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductive harm.

DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHATSOEVER!

Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes to solder/flux vapor!

If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling food.

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.)

DV-SL100

the laser may radiate through the lens of the laser pickup 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.

Warning for power supply

The primary side of the power supply carries live mains voltage when the pla y er is connected to the mains e ven 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.

Note: The screws on the DVD mechanism may never be touched, removed or re-adjusted. Handle the DVD mechanism with care when the unit has to be exchanged! The DVD mechanism is very sensitive for dropping or giving shocks.

■ PREVENTION OF ELECTRO STATIC DISCHARGE

The laser diode in the D VD mechanism ma y be damaged due to static electricity from clothes or the human body. Use caution to prevent electro static damage when servicing or handling the DVD-mechanism.

1. Grounding for electro static damage prevention

Some devices, such as the DVD player, 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. W orktable 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 DVD mechanism

1. Handle the DVD 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.
