Fan
The MH-860 is cooled by three axial fans - one each in the projector head and one in the base. The speed of
the fan (and of course the noise) can be continuously reduced if very quiet performance is required.
By the Control Board using the "FAnS" function you can choose 5 types of low fan speed operating. Please
refer to the instructions under SPEC -Special functions.
The Control Board situated on the top side of the MH-860 offers several features. You can simply set the
lighting address, read the number of lamp or unit hours, switch on and off the lamp, run demonstration
sequences, make a reset and also use special functions for manual control and service purposes.
The main menu is accessed by pressing the [Mode] key - press this one so many times until the display
shows message "A001" (with actually stored address). Browse through the menu by the pressing [Up] and
