PROCEDURE 4: TRACKER INSTALLATION
It may be necessary to replace the aircraft screws with
longer screws in order to mount the UTD mounting
a. Remove airframe screws, and install UTD mounting bracket (29328000) to chin of aircraft just above the landing
light, see figure 5.
b. Secure UTD mounting bracket with screws long enough to pass through the mating fastener and extend a
minimum of two threads.
If the UTD captive mounting bolts are lost or damaged,
use NAS1305-14 bolts as replacements.
c. Mount UTD (29310700) on bracket (make sure UTD is mounted on opposite side of nutserts), also ensure that
the night lens (red lens on UTD) is below the optical lens (clear lens).
d. Connect the UTD cable (29325701) to UTD connector and connect to the DAU receptacle marked TRACKER 1.
e. Ensure that the TRACKER MODE switch on the front of the DAU is in the DAY position.

PROCEDURE 5: NIGHT TIME TRACKING INSTRUCTIONS
The following steps are to be taken if nighttime tracking
is anticipated. If no flights will be performed after dusk,
proceed directly to task 3.
a. Ensure that the TRACKER MODE switch on the front of the DAU is in the NIGHT position.
b. Ensure that the underside, trailing edge of all blades are as clean as possible. This is necessary for optimum
adhesion of the reflective tape.
