If a weather radar system has been connected to the GMX 200 I/O, the interface should be verified as
described in this section.
1.
Select the Weather Radar (RADAR) function on the GMX 200. The RADAR should remain in the
off state with no scanning occurring when the Weather Radar Function is entered for the first time.
2.
Press the STBY/ON line select key to change the weather radar mode to Standby – allow

Press the TEST line select key to place the weather radar in Test mode. Verify that the test pattern is
displayed. Press the range UP/DOWN keys if necessary until the test pattern can be seen.

For GWX 68 and ART 2000 installations, press the HORIZ/VERT line select key. Verify that the
antenna scan changes from the horizontal scan to the vertical scan and the display changes to a
vertical scan with the test pattern displayed.

described section 5.5.9.1. If a Garmin GDL 69A has been connected to the GMX 200 I/O, the interface
should be verified as described sections 5.5.9.1 and 5.5.9.2. Each of these procedures involves verifying
