Useful zoom operation functions (ALZ function)
When the objective is switched, the zoom magnification is
automatically changed so that the field of view is maintained as it
was.
This prevents the target image from moving or disappearing and
makes it possible to observe the image while increasing or
decreasing the zoom magnification.
To activate the ALZ function, press the ALZ button on the remote
controller. The ALZ ON/OFF indicator lights. To deactivate the
LZ function, press the button again.
