FCC ill: CDG-ARTU
MAGNASTAR
EXHIBIT C
C-2000 DIGITAL AIRBORNE TELEPHONE SYSTEM
Type "C" to start the ARTU transmitting a QAM signal for loop-around testing.
Note: Execution of this command may take from ten to thirty seconds to complete during
which time the MMT may appear to be stopped or several command screens may appear
to flash by and momentarily stop before the test is configured in the MMT.
CAUTION: THE ARTU IS NOW TRANSMITTING ABOUT 10 WATTS. THIS
PRESENTS A RADIATION HAZARD FOR PERSONNEL WITHIN 5 FOOT OF THE
ANTENNA. ENSURE THAT THE LOOP-AROUND TEST SET IS SET UP AND
CONNECTED PRIOR TO INITIATING THE TEST SEQUENCE.
The MMT display screen should be as shown in Figure 6-14.
The installer will observe the RSS value for both the TSC receiver (TxRx) and the
Pilot receiver (Rx) in the MMT Status Updates window as explained in the next
step.
