Safety instruction, Warning & Notes
Safety instruction
1. General safety
2.Laser 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

.
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.
This unit employs a laser. Only qualified service personnel
may remove the cover, or attempt to service this device
(due to possible eye injury).
