Ensure that the rotary knob (fig. 1,9) is plugged into one of the USB ports at the front
(fig. 1,7) or the rear (fig. 2,6) of the Phenom.
> A blue light should be visible on the base of the rotary knob.
Even when the blue light is visible, unplug the rotary knob and then plug it back into
the USB port to ensure that connection has been properly made.
Try one of the other USB ports.
Make sure some high contrast features are in the center of the viewing window.
Use auto contrast / brightness first, then auto focus. Refer to 4.6.1. ‘Adjusting focus’
and 4.6.2 ‘Adjusting brightness and contrast’
First perform an Auto focus when fully zoomed out (this will perform a full focus scan).
When working at higher magnifications, periodically perform the Auto focus again (this
w
ill perform a ‘fine focus’). Refer to 4.6.3 ‘Magnifying the image’.
Use manual focus and contrast controls to adjust the image. Some samples may not
work well in auto mode due to sample charging or other sample related interactions
with the electron beam. Refer to 4.5.1 ‘Adjusting focus’ and 4.5.2 ‘Adjusting
brightness and contrast’.
