Voltage Indication
(Fig. 4)
1. Press the Brightness adjustment button @ to increase the voltage and
make illumination brighter.
Pressing the button ² makes the illumination darker.
2. The numerals on the left of the lamp voltage LEDs ³ indicate the
approximate voltage.
# The LED may sometimes go out (temporarily) when the motor is
driving. Even in this case, there is no fluctuation in illumination
voltage.

Light Preset Switch
(Fig. 5)
}The Light Preset switch sets the light intensity voltage to a voltage suit-
able for color photography
*
(the factory default is 9 V) regardless of the
current setting of the light intensity adjustment buttons.
*
Achieved by engaging the built-in LBD filter.
Setting the Desired Brightness (Figs. 4 & 5)
1. Press the Light Preset switch ƒ The PHOTO indicator … lights up.
2. Press one of the light intensity adjustment buttons @ ² to set the de-
sired brightness.
3. Press the Light Preset switch again. The indictor turns off, the brightness
returns to the original brightness but the setting made above is stored in
memory.
4. Hereafter, pressing the Light Preset switch sets the brightness to the in-
tensity value set in step 2 above.
# Be sure to set the light intensity voltage back to 9 V when color
photography is to be performed.
}When the Light Preset switch ƒ is pressed, a note sound (short beep) is
generated at the 9 V position.

Using the Filters
(Figs. 6 - 11)
}You can place a filter in the light path with one of the following four
methods.
· Push in the knob of a built-in filter to engage it in the light path. (Page 9)
· Place a filter on the filter mount on the base and engage in the light path.
(Page 9)
· Insert a filter in the U-FC filter cassette, attach it on the filter mount and
engage it in the light path by sliding the filter lever. (Page 9)
· Insert a filter in the U-FWT filter wheel, attach it on the filter mount and
engage it in the light path by motorized operation (using the PC). (Refer
to the separate instruction manual.)
