. Replace safety components indicated by the symbol ,
(due to possible eye injury).
only by components identical to the original ones. Any

other component substitution (other than original type)
Type : Semiconductor laser GaAlAs
may increase risk of fire or electrical shock hazard.
Wavelength : 650nm (DVD)
: 780nm (VCD/CD)
Safety regulations require that after a repair, you must

attention to the following points:
Beam divergence: 60 degree

damage.
beam.
. 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.
