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
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.
