Switch position AUTO
The dark flap is opened when you look through
the eyepiece. When you move away, it will be
closed again after about 3 seconds.
Switch position LIGHT ON
The dark flap remains open (e. g. for photo-
micrography). If the flap is still closed, it must be
opened first manually. It will then remain open.
Switch position SENSOR OFF
The person sensor is switched off. The position
of the dark flap remains unchanged.
n. b.:
The shutter key on the microscope or on the
control unit can be operated at any time. The
SHUTTER CLOSED diode indicates whether the
flap is currently open or closed.
If the dark flap is closed before the automatic
functions are switched on, it has to be opened
manually before the automatic functions take
effect.
Person sensor (option)
The dark flap can be opened automatically via a
sensor when you look through the microscope
and closed again when you look away.
This is achieved by mounting the person sensor
(order no. 505 101) onto the right eyepiece tube
and connecting the cable on the sensor to the
SHUTTER socket on the control unit for motor-
ised filter cube change.

The diode next to SHUTTER CLOSED indicates
whether the dark flap is currently open (diode
off) or closed (diode on).
You can control the dark flap manually by
pressing the key above SHUTTER CLOSED or
with the SHUT key on the control unit.
When the microscope is switched on the dark
flap is closed at first. To activate the person
sensor you first have to open the dark flap
manually.
