801.  ILS or Multi-Mode Receiver BITE Procedure
A.  General
(1)  
You do the multi-mode receiver (MMR) BITE test at the front panel of the MMR.

(2)  
There are two multi-mode receivers (MMR). MMR 1 is on the E1-2 shelf and MMR 2 is on the E1-4 shelf in the electronic equipment compartment.

SIL 001-003; AIRPLANES WITH BENDIX (ALLIED SIGNAL) MULTI-MODE RECEIVERS
(3)  The MMR BITE test does a self check for existing internal and external faults. Results of the BITE test are displayed on the LCD screen on the front panel of the MMR.

(4)  The MMR BITE test does a self check for existing internal and external faults. Results of the BITE test are displayed on the front panel of the MMR.
SIL 001-003
(5)  The MMR flight fault memory stores fault data that occurs in flight. You can view faults that occurred on previous flight legs to help isolate an intermittent fault that is not found by the BITE self-test.
SIL 004-021, 101-999
(6)  The Collins multi-mode receivers have 3 indicating lights on the front panel. However, the ANTENNA FAIL light is not used and it will stay off at all time.
NOTE: On airplanes with Collins SB GLU-920-34-15, the ANTENNA FAIL light will come on but this does not indicate a failure.
SIL 007, 008, 013-016, 019-021, 101-999
NOTE: On airplanes with GLS capabilities, the ANTENNA FAIL light on the Collins MMR may indicate GPS antenna/connection failure.

B.  BITE Procedure
(1)  Do the BITE procedure for the MMR.
SIL 004-021, 101-999; AIRPLANES WITH COLLINS MULTI-MODE RECEIVERS
(2)  Push and release the TEST switch on the front panel of the receiver to start the BITE test.
(a)  
Make sure that these indications occur: 1) All the red lights come on. 2) The LRU STATUS light changes to green after 2 seconds. 3) All the lights go off after 2 seconds. 4) The green LRU STATUS light comes on after 30 seconds.

(b)
