F1: Set Screen Contrast
Selecting F1: Set Screen Contrast reveals a Set Contrast Control screen that instructs you
on how to set and save the screen contrast to optimize the tool’s visibility in your lighting
conditions.
Important:
The Set Contrast Control tool option adjusts the permanent default contrast
setting of Tech2 display
Because of the nature of the LCD (Liquid Crystal Display), you will experience some
contrast variance.
When the temperature of the Tech2 increases the display will brighten slightly. As the
temperature of the Tech2 decreases, the display will darken. This variance is a
characteristic of an LCD screen and should be considered normal operation.
The screen contrast control setting described above may not account for the entire
variance of operating temperatures. Set a default setting which is mid-range between the
operating temperatures. Screen contrast may be adjusted during any function by pressing
the SHIFT key and using the up and down arrows for adjustment. Periodic adjustments
may be necessary, but settings outside of this application are only retained during the
current power-up session.
