has been equipped with a safety switch-off device.
The switch-off point (3-7/
3 ) is approx. 11 mm
below the upper stop (3-7/ 1 ) of the entire travel
range of 25 mm. If the safety switch-off point is
passed during fast stage lowering by 6 mm
(3-7/

at the reached point. A short beep is heard.
Further lowering of the stage is now only possible
when the

key is constantly pressed until the
entire fast lowering range of 6 mm has been
passed.
A beep is also heard when the upper (3-7/ 1 ) or
lower (3-7/ 4 ) stop is reached, and the motorized
focusing drive is switched off.
