age and make illumination brighter.

2. The numerals on the left of the lamp voltage LEDs ² indicate the ap-

proximate voltage.

Using the Light Intensity Preset Switch

}The light intensity preset switch @ makes it possible to limit the light

intensity to a preselected level regardless of the position of the bright-

ness adjustment knob. The light intensity preset switch has been preset

before factory shipment to a position which can provide optimum color

reproduction when the U-25LBD filter is engaged in the light path (approx.

9 V

mark).

1. Press the light intensity preset switch @ to the ON position. (The switch

lights when it is ON.)

2. Using a small flat-blade screwdriver, turn the preset adjustment screw ²

to obtain the required light intensity. Turning the screw clockwise increases

brightness.

3. When the light intensity preset switch is set to OFF, the brightness returns

to the level set by the brightness adjustment knob.

}While the light intensity preset switch is ON, turning the brightness ad-

justment knob does not affect brightness.
