Provides two modes of contrast adjustment (AUTO and MANUAL). The AUTO mode provides a limited contrast adjustment based upon the sensed temperature range. The MANUAL mode provides full contrast adjustment across the entire operational temperature range (0 to +120 degrees Fahrenheit or -20 to +50 degrees Celsius).

TIP:
When an extreme change in temperature is encountered the MANUAL mode is highly recommended.

To adjust the contrast

1. Press SHIFT 7 to quickly access the ADJUST CONTRAST configuration screen.

2. Press the softkey farthest to the right to switch between contrast modes (AUTO or MANUAL). TIP: When AUTO is displayed the DSAM is in the MANUAL mode and vice versa. The factory default mode is AUTO.

3. Adjust the degree of difference between the lightest and darkest areas of the screen by using the right and left arrow keys to move the contrast indicator (slider) on the ADJUST CONTRAST configuration screen. TIP: To perform a repetitive contrast adjustment, press and hold the right or left arrow key. The factory default for screen contrast is 50%.
