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
