(1) External description (Ref. Fig. 005) The face of the transponder is fitted with a handle, two attaching parts, a TEST pushbutton switch and ten LEDs. The name, color and function of the ten LEDs are as follows:
-
TPR (green) indicates that no faults are detected during the reply
-
TPR (red) indicates fault of ATC function
-
ANT TOP (red) indicates that the top antennas are incorrectly connected or are failed
-
ANT BOT (red) indicates that the bottom antennas are incorrectly connected or are failed
-ALT (red) indicates that the altitude is not in correct format

- DATA IN (red) indicates that the data input is not in correct
format
- TCAS (red) indicates that the data input from the TCAS is abnormal
- MAINTENANCE (red) indicates that the maintenance data are abnormal
- RESERVED (red) are reserved for future use.
The back of the transponder contains an ARINC 600, shell size
connector to provide electrical connections to the aircraft wiring
via mount.
Contact grouping is as follows:
- Top contact set - ATE interface
- Center contact set - System interconnections
- Bottom contact set - Power supply and bonding.

R (Ref. Fig. 005A)
R The face of the transponder is fitted with a handle, two attaching
R parts, a PUSH TO TEST pushbutton switch, six LEDs and a DATA LOADER
R plug.
R The PUSH TO TEST pushbutton switch is used to initiate the LED test
R and transponder self-test. All LEDs are on for approximately three
R seconds following self-test initiation. After three seconds, the
R front panel LEDs indicate the current condition of the unit.
R If the PUSH TO TEST pushbutton switch is not pushed again, the LEDs
R go off.
R If the PUSH TO TEST pushbutton switch is pushed while the LEDs are
R still on, the next previous flight leg is displayed.
R The transponder has the capability to store 10 flight legs. To
R display all stored flight legs, the PUSH TO TEST pushbutton switch
R must be pushed when the previous flight leg is being displayed. When
R all flight legs are displayed, all LEDs flash to indicate the end of
R the routine. All LEDs go off within 10 s after self-test is
R completed.
R The functions of the LEDs are indicated on the table below:
