CONTRAST LEVEL ADJUSTMENT
This is a "slider" bar graph control. Use the 8 key to move the graph to the left, decreasing the numbers
and contrast level. Use the 9 key to move it to the right, increasing the numbers and contrast level. In
manual contrast mode, this is a direct adjustment of the display contrast. In automatic contrast mode, this
adjusts the offset to the automatically compensated contrast, with the default set to an offset of 50.

5.2.9 ARINC 429 Configuration Pages
ARINC 429 INPUT
The ARINC 429 INPUT Pages configure the ARINC 429 input
ports. Each port can be configured independently for the desired
function(s). The ARINC 429 IN 1 INPUT allows automated
automated start and stop of the flight timer and places the transponder in ground (GND) mode upon
landing. The same input data source cannot be selected for multiple input channels 1 through 3. ADLP is
included for future use.
For a connection to a Garmin GTS 820 or GTS 850, GARMIN TAS (HIGH) must be selected.
Barometric data is not included in the GARMIN TAS format. A separate barometric data source is
required
