Focusing

Switching on and off

Switch on the motor-focus system (switch 4).
• Confirmation by acoustic signal.

Acoustic signal

There is an acoustic signal when:
• the system is switched on (one short beep)
• there is a changeover between coarse and fine focusing (one
short beep)
• the focus position is stored (two short beeps)
• the focus position is cancelled (two short beeps, pause,
two long beeps)
• the stop is reached (series of beeps)
To switch off the acoustic signal
When switching on the system, press switch 11 or 12 on the
manual control (see page 10), or activate the footswitch.
Safety measures for the stops
Read the warnings on page 5.
• The fixed stop (5) on the upper part of the column, and
the adjustable stop (6) beneath the motor housing, limit the
5
movement of the motor-focus system.
• In addition, there is an end-switch (7) on top of the motor
housing and another one beneath it. If, during focusing,
an end-switch touches the stop, there is a series of beeps
7
and the movement ceases.
4
Set the lower stop
• so that your hands have enough room between
the objective and the object, even when the motor-focus
system has reached the stop
• so that during focusing the objective cannot press against
the object and damage either objective or object.
Place the object beneath the objective.
Look into the eyepiece and carefully bring the object into
6 focus using the manual control (see page 10), the footswitch
or the PC (see page 10).
8
Use the clamping screw (8) to secure the lower stop beneath
the motor housing.

Footswitch

• To focus using the footswitch: Left-hand switch (15) = up;
right-hand switch (16) = down.
• To change between fast- and fine focusing: Press left-hand
and right-hand switches at the same time.
• Focus positions cannot be stored by means of the
footswitch.
