OVERVIEW
This section gives general procedures for routine maintenance of the 5081-T transmitter. The transmitter needs almost no
routine maintenance.
TRANSMITTER MAINTENANCE
Periodically clean the transmitter window with household ammonia or glass cleaner. The detector for the infrared remote
controller is located behind the window at the top of the transmitter face. The window in front of the detector must be kept
clean.
Most components of the transmitter are replaceable. Refer to figure below and table on next page for parts and part numbers.

Three screws (part 13 in the drawing) hold the three circuit boards in place. Removing the screws allows the display
board (part 2) and the CPU board (part 3) to be easily removed. A ribbon cable connects the boards. The cable plugs
into the CPU board and is permanently attached to the display board. A 16 pin and socket connector holds the CPU and
analog (part 4) boards together. Five screws hold the terminal block (part 5) to the center housing (part 7), and the 16
pins on the terminal block mate with 16 sockets on the back side of the analog board. Use caution when separating the
terminal block from the analog board. The pin and socket connection is tight.
