Screen Backlighting / Contrast
Basic Operation
The GPSMAP 196’s backlighting illuminates the display and keypad for optimal visibility. There are
twenty levels of screen backlighting, providing maximum fl exibility. At night, you can easily turn the
backlighting level down to prevent unwanted glare and distraction.
Screen contrast is adjustable as well. You may fi nd it necessary to adjust the contrast setting as the
ambient temperature changes.
Backlighting and screen contrast are adjusted using the RED POWER KEY and the ARROW
KEYPAD. A pop-up window shows the current settings and the progress of any adjustments you
have made.
To adjust the screen backlighting and contrast:
1. From any page, press the RED POWER KEY momentarily. A pop-up window will appear showing the
current contrast and backlighting settings.
2. Press the UP/DOWN portion of the ARROW KEYPAD to change the backlighting settings. UP will
increase backlight intensity; DOWN will decrease backlight intensity.
3. Press the LEFT/RIGHT portion of the ARROW KEYPAD to adjust screen contrast. LEFT will make
screen contrast lighter; RIGHT will make screen contrast darker.
4. Press ENTER to accept any changes and remove the screen settings window. Alternatively, if no keys
are pressed, the screen settings window will automatically be removed after fi ve seconds.
On warmer days you may fi nd it necessary to decrease the contrast setting for optimal
screen clarity. Conversely, on cold days it may be necessary to increase the contrast setting
to make screen information more legible.
