Figure 7. Dual viewing attachment
Figure 8. Power source for the light pointer
There is a light pointer in the viewing attachment that uses an external power source. Thus, you need to connect the transformer into a power outlet before using the pointer (Figure 8). After use, disconnect the transformer. Notice that you can use the monitor instead of the dual viewing attachment.
On the back side of the viewing attachment, there are two control knobs for the light pointer (Figure 9).
∙Control A:
oMove up or down to control position horizontally
oPush or pull to control position vertically
oRotate to change color from yellow or red
∙Control B:
oRotate to change brightness of the pointer
