age and make illumination brighter.

2 Using the Light Intensity Preset Switch
(Fig. 5)
}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 set to
about 4 V at the factory.
1. Press the light intensity preset switch @ to the ON position. (The face of
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.
3 Using the Filters
(Figs. 6 - 8)
}You can place a filter in the light path with either method. (Only the 32C
daylight filter is provided with the microscope.)
· Place a 32 mm diameter filter on the filter slider and engage it in the light
path. (Page 9)
· Insert up to three 32 mm diameter filters on the bottom side of the turret
and turn to engage the filters in the light path. (Page 9)
