If the FM radio fails the audio tests
❒ Check the specifications for the FM radio to make sure they match with those entered
in the software Pass/Fail Limits.
❒ Check the audio connections from the FM radio to the test set. Refer to "Making a
Connection" in chapter 2 on page 29 for a diagram showing the correct connections.
❒ Check the FM radio to make sure the microphone is not active and picking up ambient
noise.
❒ Check the FM radio to see if the audio lines carry other signals.
For example, if the audio lines carry other dc signals, a blocking capacitor in series
with the test set is required.
