RCA XV-N350BEU Preventing static electricity, Grounding to prevent damage by static electricity

1.5Preventing static electricity

Electrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged, can destroy the laser diode in the traverse unit (optical pickup). Take care to prevent this when performing repairs.

1.5.1Grounding to prevent damage by static electricity

Static electricity in the work area can destroy the optical pickup (laser diode) in devices such as DVD players. Be careful to use proper grounding in the area where repairs are being performed.

(1)Ground the workbench

Ground the workbench by laying conductive material (such as a conductive sheet) or an iron plate over it before placing the traverse unit (optical pickup) on it.

(2)Ground yourself

Use an anti-static wrist strap to release any static electricity built up in your body.

(3)Handling the optical pickup

•In order to maintain quality during transport and before installation, both sides of the laser diode on the replacement optical pickup are shorted. After replacement, return the shorted parts to their original condition.

(Refer to the text.)

•Do not use a tester to check the condition of the laser diode in the optical pickup. The tester's internal power source can easily destroy the laser diode.

1.6Handling the traverse unit (optical pickup)

(1)Do not subject the traverse unit (optical pickup) to strong shocks, as it is a sensitive, complex unit.

(2)Cut off the shorted part of the flexible cable using nippers, etc. after replacing the optical pickup. For specific details, refer to the

replacement procedure in the text. Remove the anti-static pin when replacing the traverse unit. Be careful not to take too long a time when attaching it to the connector.

(3)Handle the flexible cable carefully as it may break when subjected to strong force.

(4)I t is not possible to adjust the semi-fixed resistor that adjusts the laser power. Do not turn it.

1.7Precautions of the safe use of battery

•Store the battery in a place where children cannot reach.If a child accidentally swallows the battery, consult a doctorimmediately.

•Do not recharge, short, disassemble or heat the battery or dispose of it in a fire. Doing any of these things may cause the battery to give off heat, crack, or start a fire.

•Do not leave the battery with other metallic materials.Doing this may cause the battery to give off heat, crack, or start a fire.

•When throwing away or saving the battery, wrap it in tape and insulate; otherwise, the battery may start to give off heat, crack, or start a fire.

•Do not poke the battery with tweezers or similar tools.Doing this may cause the battery to give off heat, crack, or start a fire.

•Dispose of batteries in the proper manner, according to federal, state, and local regulations.
