10.3.1

Master Key Switch on the Compact Supply Unit

There is a master key switch on the compact supply unit for protection against unauthorized use of
the laser products. This master key switch is integrated in the interlock circuit. If the master key switch
is in the "off" position, all laser beam paths are interrupted. Then no radiation from lasers integrated
in the supply unit or the external lasers can reach the specimen area, even if the key switches of the
external lasers are in the "on" position.
The master key switch for the compact supply unit is located on the front side of the unit (see
Figure 12).

Master Key Switch on the Flexible Supply Unit

There is a master key switch on the flexible supply unit for protection against unauthorized use of the
laser products. This master key switch is integrated in the interlock circuit. If the master key switch is
in the "off" position, all laser beam paths are interrupted. Then no radiation from lasers integrated in
the supply unit or the external lasers can reach the specimen area, even if the key switches of the
external lasers are in the "on" position.
