To gain access to the jumpers, remove the cover from the AA83-001. Remove the top PCB by removing
three pan-head screws and carefully lifting it straight up.
When reassembling the unit ensure the pins and connector are aligned properly before screwing the PCB
down.
2.3.7 Mechanical
Installation
The AA83-001 can be installed in a vertical or horizontal attitude directly on the instrument console, using
the AA83-IKC Installation kit (see Section 2.5 for details).
Before the unit is mounted, make all functional tests and trimpot adjustments. Be sure the harness has
enough clearance to permit the unit to be dropped down for re-adjustment, if needed later. Make sure
unit is securely fastened to the panel, and that the connector locks are tightened before any flight is
attempted.
For proper installation, refer to the Drill Template (AA83\001\921-0) and the following steps:
Note:
The mounting nuts on the panel pots should not be removed at any time.
a)
After deciding the attitude (vertical or horizontal) of the unit, drill the required mounting holes in the
aircraft panel and insert the AA83-001 from behind the panel.
b)
Remove the protective plastic film from the black metal faceplate, and position it with the
appropriate legend orientation facing out. Secure with the mounting screws provided.
Note:
Ensure that the aircraft panel is tightly ‘sandwiched’ between the AA83-001 and the
faceplate.
c)
Rotate the inner and outer shafts of the ICS VOL / VOX potentiometer fully ccw. The outer knob
may be rotated by hand, but it may be necessary to temporarily attach the inner ICS knob to
facilitate this action. Align the white markers on the knobs to the LIVE position on the faceplate
label. Using a 0.05" Allen key, tighten the knobs onto the potentiometer shafts.
d)
Rotate the shaft of the MUSIC VOL potentiometer fully ccw. Align the white marker on the knob
to the MIN position on the faceplate label. Using a 0.05" Allen key, tighten the knob onto the
potentiometer shaft.
Note: Make sure there is enough clearance between the concentric knobs so that rotating one
does not also move the other. A piece of paper makes a good spacer when setting up
the clearance.
2.3.8 Post-Installation
Checks
If any preset requires adjustment, be sure this is carried out before the aircraft leaves, and that the unit
and its mating connector are secured before departure. Make all required log book entries, electrical
load, weight and balance amendments and other paperwork as required by your local regulatory agency.
