Contrast Adjustment
The LCD contrast is already set for normal viewing when the
UltraBlock USB is shipped from the factory. However, you
may need or want to adjust the LCD contrast to suit your
preferences or work environment. To adjust the
LCD contrast, carefully insert a #0 phillips head screwdriver
in the hole as shown in the above image. To make the dis-
play darker, rotate the screwdriver counter-clockwise. To
make the display lighter, rotate the screwdriver clockwise.
Buttons The UltraBlock USB has two buttons, "Menu" and "Enter."
These two buttons may be used to navigate additional infor-
mation screens on the LCD display. The arrangement of
