Auto Back Light
The SeekTech is equipped with an automatic LCD back-
light. Whenever a key is pressed, the backlight is acti-
vated to aid viewing for 80 seconds.
Adjusting the LCD Screen Contrast
LCD contrast is set at the factory and should not normally
require adjustment. Optimal contrast is set when the
background remains white, while the black pixels are set
to be as dark as possible.The LCD can be adjusted to
completely white or completely black, which will affect
readability.
LCD contrast may change with extremes in tempera-
ture. When the screen is exposed to high heat from direct
sunlight it may darken. It is recommended that the screen
be shaded if it is to be exposed to excessive sunlight. Use
the shoulder strap to cover the screen if needed.
If the display appears too dark or too light when it is on, it
is likely that the LCD contrast has become misadjusted.
First try powering the unit OFF and then back ON. If the
problem persists adjust the LCD contrast darker or lighter
as needed.
To adjust the LCD Contrast:
1. Press and hold down the select key.
2. Simultaneously press the up arrow key to lighten
the display or press the down arrow key to darken the
display.
