Prior to insertion of connector into rear of unit, check polarizing key position between
contacts 8 and 9. Refer to Figure 2-6 to check correct position of polarizing key.
2.3.4.D. Extraction of Contact from Molex Connector
2.3.4.D.1 Slip the flat narrow blade of a Molex HT-1884 contact ejector tool, P/N 047-
05099-0001, under the contact on the mating side of the connector. By turn-
ing the connector upside down one can see the blade slide into the stop.
2.3.4.D.2 When the ejector is slid into place, the retaining tab of the contact is raised,
allowing the contact to be removed by pulling moderately on the lead.
2.3.4.D.3 Neither the contact or position is damaged by removing a contact; however,
the contact should be visually checked before reinstalling to be certain that re-
taining tab “A” extends as shown in Figure 2-4 for retention in connector.
2.3.4.E. Coax Connector
Refer to Figure 2-7 for instructions for mounting the right angle coaxial BNC connector
to the coax cable. Install the connector into the mounting rack.
2.3.5 KY 96A, KY 97A Installation
2.3.5.A. Looking at the top of the unit, make sure the front lobe of the hold down device
is in a vertical position.
2.3.5.B. Slide the unit into the mounting rack until the front lobe touches the mounting
rack.
2.3.5.C. Insert a 3/32 inch Allen wrench through the hole in the front panel to engage
the locking screw. Turn clockwise until the rear lobe engages the mounting
rack. Continue turning until the unit is secure in the mounting rack. DO NOT
OVERTIGHTEN.
2.3.5.D. To remove the unit turn the locking screw counterclockwise, using a 3/32 inch
Allen wrench, until the unit disengages from the mounting rack. Pull the unit
out of the mounting rack by pulling on the metal tabs located behind the front
panel on each side of the unit.
2.4 POST INSTALLATION CHECKS
An operational performance flight test is recommended after the installation is com-
pleted to insure satisfactory performance of the equipment in its normal environment.
Check all aircraft control movements to be sure no electrical cables interfere with their
operation. To check the communications transceiver, maintain an appropriate altitude
and contact a ground station facility at a range of at least 50 nautical miles. Then con-
tact a ground station close in. Pull the volume control out to defeat the automatic
squelch feature and listen for any unusual electrical noise which would reduce the
comm receiver sensitivity by increasing the squelch threshold. If possible, verify the
communications capability on both the high and low end of the VHF comm band.
