Adjust LEVEL SET (fig. 3) as necessary for midrange voltage
obtained in (7) above.
14. Tab Adjustment
a. Performance Check
(1) Connect AUDIO OUT connector of TI to true rms voltmeter (A8), using cable
(B8) and adapter (B1).
(2) Position controls of TI as indicated in (a) through (e) below:
(a) VOR control to 0.
(b) METER switch to CAR.
(c) NAV-GS switch to NAV.
(d) AUDIO SELECTOR switch to 90 ∼.
(e) LOG-GS control mark aligned with top mark on DOWN-RIGHT tab.
(4) Turn AUDIO SELECTOR switch to 150 ∼.
Record indication of true rms
(5) Observe that indication obtained in (3) above is twice the voltage indicated in (4)
above. If not, perform b below.
(6) Turn LOC-GS control of TI until mark on knob is aligned with top mark on UP-
LEFT tab. Record indication of true rms voltmeter.
(7) Turn AUDIO SELECTOR switch to 90 ∼.
Record indication of true rms
(8) Observe that indication obtained in (6) above is twice the indication observed in
(7) above. If not, perform b below.
b. Adjustments
(1) Repeat a(2) through (4) above.
(2) Turn LOC-GS control until indication in a(5) above is obtained.
(3) Loosen screw on DOWN-RIGHT tab and align top mark of tab with mark on
