1-10. Location and Description of ALT Major Components (fig. 1-2)
a. Receiver (1). This unit is a barrel-shaped housing with a glass dome. The unit contains the laser seeker. It
senses the reflected laser signal from the target. The housing circuits are used to track the incoming laser signal from
the target. A receiver fault during self-test is indicated by the RU lamp on the control panel.
b. Electronics Assembly (2). This unit contains the ALT plug-in modules and power supply. Three front panel
connectors provide power and signals to the unit. A top cover seals the unit. This cover is not removed, except when
the unit is being repaired. The cover protects the modules, power supply, and wiring, The unit is located in the aircraft
behind the receiver. An electronic assembly fault during self-test is indicated by the EU lamp on the control panel.
c. Control Panel (3). The control panel contains the ALT controls, lamps, and lights. The two controls are the
MODE and CODE thumbwheel switches. The four lamps are the TRACK, RU FAULT, EU FAULT, and GO lamps. The
mode switch is lit by a light embedded in the plastic (edge-light panel). The control panel is located in the pilot's cockpit.
