# The LEDs may turn off (temporarily) when the motor is driven, but the
illumination intensity does not vary even if this occurs.
3. The marking 5 is the reference position indicating 9 V, which is the
suitable intensity for color photography (using LBD filter).

the observation and side port paths.
The selected light path can be confirmed with the LED on the side of the
