Furuno MU-190 User Manual

Note: When you connect the monitor unit to FAR-21x7, FEA-2107 or FCR-21x7, you can turn the 
power on/off and adjust the brilliance via the application of the FAR-21x7, FEA-2107 or FCR-21x7 
only (see section 2.1).

The dimmer for the power LED and keys changes with the display brilliance. Also, when you con-
nect the monitor unit to FAR-21x7, FEA-2107 or FCR-21x7, the dimmer for the power LED and 
keys changes with the brilliance modes (Day, Dusk, Night) of those models. When you connect 
the monitor unit to the equipment other than FAR-21x7, FEA-2107 or FCR-21x7, the control is 
done from the MU-190. If the keys of MU-190 are not illuminated, provide external, dimmable illu-
mination, e.g. gooseneck lamp.

How to turn on/off the power depends on the setting of the slide switch. The slide switch is set 
when the monitor unit is installed. See section 1.8.

Note: The screen refreshes slower in low ambient temperature.
