Setting RX audio level to site operational level
After the receive tests, ensure that the audio level recorded in the Receive
Audio Level test is the same as the site specific operational level. If the two
levels are different, perform the Receive Audio Level test and change the
receive audio level to the site specific operational level by using the T
command.
Set the RX audio sensitivity with the T command.
>T
The DRU will prompt as follows:
Enter TX or RX and a decimal dBm value (TX:-28...
-10);(RX:-28...-16)
Enter:
>RX -xx.x
(change this value as required to obtain the operational
receive audio level)
Note: A change of 1 dBm is approximately a change of -0.27 kHz
deviation.
The Audio Sens RX status on the screen will show:
Audio Sens Rx: -xx.x
(site specific operational level)
Use the Y command to perform a reset on the DRU after the tests.
>Y
At the command prompt, perform a warm reset on the DRU by entering:
>W
The DRU will return to its normal working condition after the reset.
Disconnect the interface terminal from the DRU.
At the MTX, put the DRU back to service.
