Section II
i. The phase localizer function of the receiver is
megacycle band. Set meter to red line with CARRIER
tested in the same manner as tone localizer except
SET control.
LOC is selected onthe AUDIO SELECTOR and
the receiver control box.
e. Rotate the LOC-GS control over the range
covered by the left segment and note the upward de-
flection of the cross pointer. At the middle of the
check the operation of glide slope receivers follow
segment the deflect ion should be 2 dots on Course
the procedure outlined below.
Indicator ID-249A/ARN. Repeat this procedure for a
downward deflection with the other segment.
a. Carry out adjustments listed under paragraph
2-3, above.
NOTE
b. Make connections in accordance with instructions
Test of paragraph e. is based on a standard
in paragraph 2-5, above.
glide slope receiver sensitivity of 90 micro-
amperes for a 2 db ratio between tones.
c. Turn AUDIO SELECTOR to GLIDE SLOPE po-
s ition and NAV-GS switch to GS position.
f. Check the crosspointer centering by turning the
LOC-GS control to the small center segment. The
d. Tune Signal Generator SG-13/ARN and glide
crosspointer should be centered when the LOC-GS
slope receiver to desired channel in 329.3 to 335.0
