Pressing this key the beam shutter is opened and pressing this key a
second time the beam shutter is closed again (refer to
section 5.2 ). The
beam shutter is closed automatically when the controller is switched on
(key switch on the controller in position I).

LASER STANDBY - L
ED
The L
ED
goes on when the controller is switched on. This then shows that
the laser is operational. However, no laser beam is emitted yet as the
beam shutter is still closed (L
ED
ON is out). The L
ED
goes out when the
beam shutter key is pressed and thus the laser beam is emitted (L
ED
ON
is then on).

LASER ON - L
ED
The L
ED
goes on when the beam shutter key LASER is pressed and thus
the laser beam is emitted. At the same time the L
ED
STANDBY goes out.
Pressing the beam shutter key LASER a second time the beam shutter is
closed and the L
