2.0 Safety instruction

1. General safety

Safety regulations require that during a repair:

. Connect the unit to the mains via an isolation

transformer.

. Replace safety components indicated by the

symbol

Only by components identical to the original ones.

Any

Other component substitution (other than original

type)

May increase risk of fire or electrical shock hazard.

Safety regulations require that after a repair, you

must

Return the unit in its original condition. Pay, in

particular,

Attention to the following points:

. Route the wires/cables correctly, and fix them with

the

mounted cable clamps

. Check the insulation of the mains lead for external

Damage

. Check the electrical DC resistance between the

mains

Plug and the secondary side:

1) Unplug the mains cord, and connect a wire

between

The two pins of the mains plug.

2) Set the mains switch the “on” position (keep

the

Mains cord unplug).

3) Measure the resistance value between the

mains

plug and the front panel, controls, and chassis

bottom.

4) Repair or correct unit when the resistance

measurement is less than 1M Ω

5) Verify this, before you return the unit to the

customer/user (ref. UL-standard no. 1492).

6) Switch the unit “off”, and remove the wire

between

the two pins of the mains plug.

2. Laser safety

This unit employs a laser. Only qualified service

personnel

May remove the cover, or attempt to service this

device

(due to possible eye injury).

Laser device unit

Type :Semiconductor laser GaAIAs

Wavelength :650nm (DVD)

:780nm (VCD/CD)

Output power :7mW(DVD)

:10mW(DVD/CD)

Beam divergence:60 degree

Note: Use of controls or adjustments or

performance of procedure other than those

specified herein, may result in hazardous

radiation exposure. Avoid direct exposure to

beam.
