3.2.3.6 Test Pattern Selection
A. Initially, turn function switch from OFF to TST position.
B. Check the indicator display. The test pattern appears 7 or 8 seconds after the indicator func-
tion switch was rotated from the OFF position to the TST position. The exact point of test pat-
tern termination or range duration of each color is shown in figure 3-3. The presence of four
distinct colors, in the proper order, is important.
C. If indicator function switch is already in the ON position, move to the TST position and observe
that the test pattern reflects the range selected before the function switch was moved; e.g., if
range was set for 160 miles, the test pattern will extend only to about 50 miles on the 160-mile
range. set the range to 80 miles for the best test pattern presentation.
3.2.3.7 Turn-off Procedure (on the ground)
The ART 2000 Antenna/Receiver/Transmitter will tilt the antenna down, for increased radar re-
ceiver protection, when the indicator is switched to SBY and OFF position.
Always turn the indicator function switch to SBY or OFF before disengaging the avionics master
switch in the aircraft. The system will power-down in about 5 seconds after switched to the OFF
position, to allow time for the antenna to move to the down position (-25
°
).
