UNICO M250 Forums

How do you switch between 110V and 220V on an Unico M250 microscope, please?

The bottom of the scope shows it to be switchable., and I need to use it at 220V/50Hz.

Actually, I am not sure of the model. It appears to be an M250, and the tag on the bottom says:

• Series: H600
• Input: 110V/60Hz or 220V/50Hz Switchable
• Lamp: Halogen 6V20W,G4 pin
• Fuse: 250V1.5A @5x20mm

Many thanks,

Jeff Finger
