5. Verify that clockwise rotation of the OFF/BRT knob increases display brightness and counter-
clockwise rotation decreases brightness. The screen should be completely dark with the control fully
counter-clockwise. Adjust to a comfortable viewing level.
6. Verify operation of the pushbuttons (figure 3-1 shows location of softkeys):
a. Press softkey (A), i.e., MENU. This should cause the system menu to be displayed with “ Weather
View” menu item highlighted.
b. Press softkey (B), i.e., 360° . The display should return to the weather mapping mode, 360°
Weather View at the 200 nmi range.
c. Press softkey (C), i.e., down-arrow. The weather view range should change to 100 nmi.
d. Press softkey (D), i.e., up-arrow. The weather view range should return to 200 nmi.
7. Access the Service Menu (refer to paragraph 4.4) and verify the information (i.e., heading source,
heading flag, jumper sense, heading, inhibit line and antenna mounting location) identified on System
Data Page 2 of 3).
NOTE
If stepper heading is used, the heading will not agree with the HSI. Stepper
heading is relative to aircraft heading.
8. From the Service Menu, enter the noise monitor mode.
9. Repeatedly key the aircraft communications radio microphone:
a. If keying the transmitter does not cause strike data to appear on the CRT, proceed to step 13.
b. If strike data appears on the CRT when the transmitter is keyed, wire the inhibit line to the
microphone key switch (see figure 2-5).
10. From the Service Menu, access System Data Page 2 of 3 and verify that when the transmitter is keyed
the state of the Inhibit Line transistions from off to on.
11. From the Service Menu, enter the noise monitor mode.
