Garmin MX20 - Manual (Page 66)


Detailed Operation
Traffic Status Indicators
The following status indicators are displayed in the lower right portion of the display:
“TIS Operating” to indicate the TIS-A Sensor is operating and within TIS-A service coverage.
“TIS Coasting” to indicate that the target information is between 6 and 12 seconds old. This may happen if the
TIS-A sensor has missed a radar sweep. Target brightness is also reduced to indicate this condition.
“TIS Unavailable” to indicate the TIS-A sensor is operating, but outside of TIS-A service coverage.
“TIS Standby” to indicate the TIS-A sensor is in standby mode and not processing TIS-A information, even if it
is available.
“Traffic Off Scale,” noted in amber in the lower center of the display, indicates that traffic has been reported but
is not displayed because it is beyond the current map scale (zoom level).
