F. Set magnetic heading reference system to 0-degree heading (Ref 34-21-00) using SET HDG knob on compass controller (panel P5).
G. On SN 351-399, perform the following on both VHF NAV control panels:
(1)
Position DME mode selector to STBY.
(2)
Press and release MAN switch/indicator. Check that MAN
switch/indicators remain illuminated.
(3)
Hold DISPLAY TEST button depressed while verifying that frequency display indicates 188.88.
H. On XA ALL EXCEPT LH 011-099 and SN 351-399, position VHF NAV control panel function selectors to VOR/ILS and verify that panel and dial lights are on.
I. Position captain's and first officer's VOR/ILS-INS switches to VOR/ILS. Check that HSI VOR/ILS-INS annunciators indicate VOR/ILS.
J. On XA ALL EXCEPT AT airplanes, position captain's VOR/ILS switch to CAPT 1 F/O 2. Verify that switch position annunciator indicates CAPT 1 F/O 2 and that NAV source annunciator in captain's HSI indicates 1 and F/O's indicates 2. On AT ALL, position captain's VOR/ILS 3 switch and captain"s and F/O's DEV switches to NORM. Verify that NAV source annunciator in captain's HSI indicates 1 and F/O's indicates 2.

4. Operational Test - VOR/ILS Navigation System
____________________________________________
A. General
(1) The following operational test for the VOR/ILS navigation system is a fast, preflight checkout to determine that the system is operating properly. It requires only the use of the built-in test features of the equipment installed in the airplane.
B. Test VOR/ILS Navigation System
(1)
Perform prepare to test VOR/ILS Navigation System procedures in paragraph 3.
(2)
Select local LOC frequency on captain's VHF NAV control panel.
(a)
Verify that captain's HSI course deviation bar is deflected normally. When the airplane is to the left of localizer beam, course deviation bar is deflected to the right of indicator. When the airplane is to the right of the localizer beam, course deviation bar is deflected to the left of indicator.
(b)
Verify that LOC station identification code is audible on flight interphone system (Ref 23-51-00).
(c)
Tune to local VOR station and check for proper VOR filter voice and range audio operation using cockpit audio selector panel controls and flight interphone system.
