g. Observe the High Gain RSSI values. They should be between 20 to
25 counts with the transducer disconnected.
h. Leave the transducer cable disconnected if you want to run the next
test.
5-4.3 Transmit Test
This test runs a through test on the ADFM’s transmit path electronic cir-
cuits.
a. Start BBTALK . Press the
End
key to wake the ADFM.
b. Type
CP
to clear the fault log.
c. Type
PT4
. A message similar to the following should appear.
