 (1) Activation of the Self-Test A functional self-test of the DME Interrogator may be initiated from the normal mode screen by pressing the TEST pushbutton switch as designated on the front panel LCD. A self-test mode is initiated and a "TEST IN PROGRESS" message is displayed approximately one second after the TEST pushbutton is pressed. This message is displayed for four seconds with a moving thermometer along the bottom of the LCD indicating the progress of the test from one to five seconds. At the end of the self-test, either a TEST COMPLETE, NO FAILURES message screen or a TEST COMPLETE, FAILURES message screen is displayed. The TEST COMPLETE, NO FAILURES screen contains two pushbutton selections (MAINT and RETURN). The TEST COMPLETE, FAILURES screen also contains two pushbutton selections (MAINT and WHY?).
 1EFF : ALL 1 34-51-00Page 45 1 1 May 01/05 1 1 1CES 1 For both screens, pressing the left (MAINT) pushbutton initiates the extended maintenance pages of the system for troubleshooting. The right (RETURN) pushbutton associated with the TEST COMPLETE, NO FAILURES screen returns the system to its normal mode screen. The right (WHY?) pushbutton associated with the TEST COMPLETE, FAILURES screen places the system in the display-failures mode where individual system failures (fault memory codes) are displayed, one per page.

 ---------------------------------------------------------------------------| TEST | TESTED INTERNAL COMPONENTS | DURATION | ACTIVATION | | DESIGNATION | | | CONDITIONS | |----------------|----------------------------|----------|----------------| | Power-up | Power supply module | | Power interrupt| | test | | | > 200ms | |----------------|----------------------------|----------|----------------| | MCDU system | - processor board | | Relevant MCDU | | test | - receiver | | menu line key | | | - synthesizer | | selection | | | - power amplifier | | | | | - driver | | | | | - AGC circuitry | | | |----------------|----------------------------|----------|----------------| | FACE TEST | ditto | | Relevant P/BSW | | | | | activated on | | | | | the receiver | | | | | face | ---------------------------------------------------------------------------
(2) Activation of the test on the indicators The DME 1(2) test function can be activated only by pressing the pushbutton switch on the face of the interrogator. The following sequence is then generated on the output of the equipment:
 1EFF : ALL 1 34-51-00Page 46 1 1 Aug 01/05 1 1 1CES 1 ---------------------------------------------------------------------------| DURATION | MESSAGE | RMI DISPLAY | |---------------------|-------------------------|-------------------------| | 2 s approx. | FAILURE | Blanked window | | 2 s approx. | NCD | Dashed lines | | Duration of test | TEST | 0.0 | ---------------------------------------------------------------------------
