the “High”, “Middle” and “Low” brightness levels respectively, the orange lamp will light.
When the available illumination time elapses, the orange lamp will start blinking.
Charge the batteries immediately or replace with fully charged batteries. When the

5-5-3 Adjusting Illumination Field
The illumination field size can be changed continuously by turning the Diaphragm ring on the
Illuminator. The field size may be adjusted from 48 to 100mm approximately at a 40cm of
distance. By turning the Diaphragm ring clockwise, a wider illumination field size may be
achieved as shown in Fig. 5-5-4.
