(15) Proceed as follows to check the two-pulse beacon format.
(a) Press and hold the PUSH CODE button and observe that the beacon code displayed in the

(b) Observe the display for any 2-pulse beacon replies.
(c) If a 2-pulse beacon reply is observed, repeatedly press the PUSH CODE button until a
beacon code (e.g. B3) appears in the display between the "hash marks".

The selected range must be set for 2,5,
10,20,40, or 80 mile range to identify 2-pulse
beacon replies.
(d) Observe the beacon code number selected and the beacon code number displayed by the
beacon marks are the same number.

2.8.2 Flight Check procedure
Note
+
Vertical gyro precession may be experienced
during take-off or during prolonged aircraft
maneuvers. Antenna stabilization may
therefore suffer a 3° to 5° error for as long as
five minutes after the maneuver.
2.8.2.1 Check Test Pattern
Rotate the Function Select Switch on the Radar Control Panel to the TEST position. Set the range to
80 miles. Adjust the brightness (BRT) control on the MFD display as necessary to evaluate the test
pattern. Basically, check that update is occurring and that the five colored bands are correct.
