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
ALZ function, press the button again.
Example: Starting from an objective magnification of 0.5x, zoom magnification of 10x and eyepiece magnification of 10x
equaling a total magnification of 50x, switch the objective as follows;
10x
10x
0.5x
Switching the objective
from 0.5x to 2x
Switching the objective
from 2x to 0.5x
