12. Contrast Adjustment
The H30 has an automatic contrast feature that will adjust the LCD screen contrast based off of temperature. If
the contrast is too light or too dark the contrast can be manually adjusted by going to the MAIN MENU, then
UTILITIES, then ADJUST DISPLAY. Increasing the CONTRAST setting will darken the display, decreasing it
will lighten the display.
The automatic adjustment can be disabled if display contrast problems occur.
